06 8 HP Manual Tilt Reverse Lock Mechanism ?

[1st_Yamaha]

Hi everyone...I'm working on my neighbors 2006 Yamaha 8 HP T8ELH .... Manufacturers date code is February 2006.

I believe the serial number might be 1011863 as that's what's on the white sticker next to the model number T8ELH....There's also on the sticker 60S and an L.

The engine has always kicked up when put into reverse gear from new under acceleration....Neighbor never gave it much thought and he just pushed the engine back down by hand and just let the engine idle slowly while in reverse each time thereafter once the shock of went away....The engine is on a 22ish-ft sail boat and the boat is on an easy lake/marina to navigate.

Right now the engine is off the boat due to the impeller losing 5 of it's 6 blades and was getting very warm and barely shooting out water.

So with the engine home, we're now trying to figure out why the engine didn't want to go fully down into the locked position.

At our first look it appeared the main engine vertical portion wasn't aligned properly to the center of the 2 side mounting clamp brackets....Item numbers 1 and 2 in the parts link below.

The engine was hitting on the starboard side clamp bracket as you lowered the engine probably a bit over an 1/8 of an inch it seemed like.

All the horizontal engine bolt clamp brackets were tight. But between loosing the horizontal bolts to the mounting bracket and a bit of grinding to the aluminum brackets, we're now able to get the engine to go down in-between the mounting brackets but there's now another issue once the engines almost all the way down.

The side mounting brackets have 3 open groove "catches" to help position the engine in an upwards position for out of water type storage.....As you lower the engine after releasing the black tilt release lever, the engine wants to stop in the lowest storage position and won't go all the way down to lock on the tilt pin rod.....That is until I manually reach up by hand and pull further outwards on the receiver assembly (which will be item 26 in the parts link below) Then I can bypass the lowest storage position and lock the engine down on the tilt rod/pin.

Because he says it's been happening since he bought the engine new in 2006, My guess was there may have been some type of service literature/bulletin regarding an issue similar to this that might be found within a Yamaha dealers only communication network/website under their service literature section something like Mercruiser has in their dealers only website....Or I guess it could be on paper too? If one exists.

I'm hoping either someone recalls seeing this issue in the past or would be kind enough to have a look through the Yamaha outboard service literature and see if there might be a written recommendation someplace out there.

Here is the parts guide for the area I'm working on with this engine model.

Sorry if this seems long winded to get to the main issue at hand.

Thanks Everyone.....Much Appreciated.

Just bumping this thread back up to the first page due to it appears some first threads needs to get moderators approval before allowed to show on open forum.

Moderator approval seemed to take close to 1 1/2 days possibly due to the time I first posted of around 1:00 AM PST..... In-turn sending new questions to page 2 or higher which could mean some threads might not be getting full attention from those that enjoy helping out where they can. With that I completely understand the need for Mod approval due to the high volumes of spammers out there wanting in.

Thanks all for your valuable time of considering to help me out with this one.

Are you saying that the tilt lock mechanism is not working or that you don't know about the tilt locking mechanism? How it works that is.

It appears that the tilt lock mechanism is not automatic as it might be in some models. On some models the act of shifting the motor into gear will also lock the motor from being able to tilt us. Not so in the T8. There is a dedicated handle that has to be positioned before shifting into reverse, to prevent the propeller from pushing the lower unit upwards.

See page 21 of the owner's manual linked below.

I am not much help on finding info from Yamaha on this problem, but seems like something had to be bent to cause you to grind away metal.

is the bracket you have to move by hand too stiff or binding

[panasonic]

There are two hat bushings, item 8 on diagram you refer to. Are these bushings in place? The hats on these bushings are what keep the engine centered in between the two outside clamp brackets. I believe they are plastic bushings....so possibly one of the bushings has the hat broken off somehow allowing the engine to shift to one side....

Unless something is seriously bent you should not have to grind away material for it to fit down between the side brackets.

The three notches you refer to are: top notch is engine all the way up....the other two positions are for shallow drive. The engine won't lock down when in shallow drive position...it has to be ALL the way down to lock on the trim rod.

My buddy down the road from has a 2007 F15 and it appears to have the exact same transom bracket setup as yours...I will look at it tomorrow and see if I can see the bushing hats I was talking about..

Could you possibly post a few pictures of the transom bracket?

Testing to see if the photos will turn out....I don't believe they will though.

Are you saying that the tilt lock mechanism is not working or that you don't know about the tilt locking mechanism? How it works that is.

Starting to think a little bit of both on this unit but it's mostly as in not working correctly.

It appears that the tilt lock mechanism is not automatic as it might be in some models. On some models the act of shifting the motor into gear will also lock the motor from being able to tilt us. Not so in the T8. There is a dedicated handle that has to be positioned before shifting into reverse, to prevent the propeller from pushing the lower unit upwards.

See page 21 of the owner's manual linked below.

Yes and thank you for that...The owners manual seems to offer advice on both manual and power trim almost right at the same time. I've been reading/using that link plus the paperback owners book manual too.

On page 21 the Tilt Support "Knob" appears to be for Power trim as there's a Ram in the image holding up the engine. This model has the Tilt Lock Lever and doesn't have the "Knob" which at one point after check the manual I went looking for the knob or another mechanism that might help move the receiver assembly out further so it won't catch the storage holders.

The first top left image on page 22 shows a really good image of the receiver assembly resting in the highest storage position holder. The image shows the/a spring too.

The main problem right now is figuring out how to get the receiver assembly to be pushed out a bit further as the engine is coming down and not get caught up in the last storage groove so the engine will go down and lock onto the Trim Rod Tilt Pin.

The Tilt Lock lever will release/unlatch the tilt lock mechanism from the tilt pin and appears to move okay as nothing is hung up or sticky up in there. There was some soft webbing debris up in there from spiders but I've cleaned all that out which didn't help repair the issue....Again right now the only way to lock the engine down is to reach up there and help move the receiver assembly.

Looking over all the parts images seems to indicate all the hardware components are in place still.

Thanks for helping me out with all of this.

I am not much help on finding info from Yamaha on this problem, but seems like something had to be bent to cause you to grind away metal.

is the bracket you have to move by hand too stiff or binding

Unfortunately no the moving mechanisms all seem to move relatively easy. There's no obvious binding or stiffness thus far... I did have to clean up in there plus I lubed it with WD40 just in case but it didn't seem to help any.

I also don't see anything bent at this time though each time I work on it I'm looking for something I may have missed.

Thank you for your reply too.

There are two hat bushings, item 8 on diagram you refer to. Are these bushings in place?

Yes though I saw the bushings while slightly loosening up the two bigger nuts that holds / seems to help adjust the engine to help fit a bit better within the two brackets....I went back out tonight to make sure they seem in place and nothing out of the ordinary as far as defectiveness just short of not removing them though. They seem okay right now though it may not mean much, this issue I am experiencing, appears to have been this way from new from what he is saying.
The owner seems to think there might be 100 hours on the engine now but not much over if there is.....It's a good running engine out side of this issue.

The hats on these bushings are what keep the engine centered in between the two outside clamp brackets. I believe they are plastic bushings....so possibly one of the bushings has the hat broken off somehow allowing the engine to shift to one side....

Unless something is seriously bent you should not have to grind away material for it to fit down between the side brackets.

Thank you for this info as it helps with knowing what's happening in that area better....
At first thoughts of trying to figure out why the engine won't fit between the brackets it seemed at the time the engine was way to far over to the starboard side and it didn't seem like there'd be enough wiggle room to slide the engine over to the port if I loosened up the two bigger nuts....Honestly I wish I tried that before taking the grinder to it because just after I got the engine to go down further to the last storage position and trying to figure out why it won't go into the locked position, I finally took the time to loosen the two nuts and with a small pry bar, I was able to move the engine over just a bit for a better center....It's still not perfectly center but it's closer then it ever was....If that makes sense at all. I still have to tighten the nuts so I'll play with the adjustment some more when I get a better chance..... There's really no time limit with this one thus far.

The three notches you refer to are: top notch is engine all the way up....the other two positions are for shallow drive. The engine won't lock down when in shallow drive position...it has to be ALL the way down to lock on the trim rod.

Thanks for the better clarification on wording...Shallow drive vs my storage position heights....That makes sense...Much like raising the power trim up just a bit in shallow waters.

My buddy down the road from has a 2007 F15 and it appears to have the exact same transom bracket setup as yours...I will look at it tomorrow and see if I can see the bushing hats I was talking about..

Could you possibly post a few pictures of the transom bracket?

Thank you for this offer, that would be highly appreciated.

I took some photos tonight.... This forum seems to want a URL from a website address to post photos.
I don't believe the photos I tried posting will show up correctly plus I'm not exactly sure what happen to the photos at this point but I did try posting the photos to what I believe was this thread but when I went to post them, a message popped-up and said it needed Moderator approval so they may show up sometime out of the blue if the links I posted even work as I had to post the links of/through my email and I used the insert email address yellow icon in the forum tools. If it does show up, they may even appear as a whole new thread as that was sort of what it looked like when the quick message popped-up.

^ If not I may have to email them to you/someone if anyone has the desire to want to see them.

Unfortunately photobucket went from allowing free photos to wanting a crazy amount of $$$ to host your new and old photos and if you don't become a paying customer, all your old photos you posted over the years have now disappeared making it hard on website forums such as these to help get a visual of what one is/was talking about.
Many how to write-ups by past members will no longer be as helpful if the thread was done using photo images.

Thanks again everyone one for your efforts...They are much appreciated.

This gentleman has still not figured out what is going on with the tilt on his engine. He contacted me via PM. His posts are all going to the moderator and he can't seem to get any pictures posted.

I will post a couple of pictures for him when he sends them to me.

Can you recommend a picture saving site for him....he used to use photobucket

Thanks

Here are a few picture's of OP's engine transom bracket.

I cannot tell from the pictures what is wrong. If I had to guess though....I would think that the Main pivot shaft may be bent. He says that this engine has been used for year's without being locked down when in reverse (manual lock) and kept popping up like it would. The engine comes back down with quite a bang when allowed to pop up high for sure.

I cannot see how the center engine bracket could be off to one side so much unless something is bent.

The lock down bracket with the two little claws, that grab the trim pin, has a link rod which is easily bent, this may be why the engine wont lock down by itself...

Sorry pictures upside down for some stupid reason...which I cannot figure out.

[1st_Yamaha]

Final update for all that was following along of why the engine wouldn't lock down onto the tilt rod pin....Thanks to Panasonic for instilling into me that something must be bent had me re-look at the moving mechanisms more carefully and that's when I saw the portside arm of the receiver assembly (item number 26 closes-side to item number 22) was bent outwards vs how the starboard side was at rest.

The bent arm wasn't pushing out the receiver assembly far enough to clear the last shallow drive position on it's way down.

With the arm readjusted inwards, the engine now goes all the way down to the tilt pin and locks like it should....Then while raising the engine back up, the receiver assembly will catch/stop in each of the shallow drive positions like it should until the full upwards storage position is reached. Today was a good feeling at finally figuring this out.
