Remove power to ..

[Guttsetlk115]

Hello Everyone
I need to install the inner anodes in the motor
(Long story)
My question is :
Do I need to pull the power head to remove the lower head bolts ?
Thank you for any input !!

[pstephens46]

Forum will need more info. Year and entire model number. Curious though, what makes you think you need to replace internal anodes?

Hello
Yes of course
It is a 1985
Yamaha
115
Etlk
I had what I thought was a good mechanic "rebuild " this motor .
When I got it back it was missing all kinds of little parts .
Missing the new prop that was on it
Missing the anode for the bracket
Missing the fuel connect clip
Missing the trim gauge rheostat on the brack
Missing a few other assorted nuts and bolts
I almost had to get a lawyer to get it back after 4 months
The man over promised and did not care
When confronted he was flippant and said "just drop it back off"
I put a new trim tab on this spring . It now looks about ten years old .
The new paint on the motor is really starting the flake now .
The power head is much hotter on one side than the other .
I will need to clear the water jackets . I want to see if the anodes are there and if they are viable .

Shame on that guy! Not sure about having to remove the powerhead to get access on that model. Perhaps some of the pros will chime in. Sounds like the major issue is one bank running hotter than other. So if you have to disassemble to fix this issue, you would be correct to replace any anodes you come across.

Being a V4, it's very un-likely you have to remove the block to get the heads off.

Looking for enough access with a wrench/rachet should tell.

Here's your main parts fisch, anodes, parts 11:

He is concerned about one bank running hotter than other. I am not familiar with these V-4 2 strokes. Is that normal? Should he be concerned?

Wonder if the mechanic replaced thermostats?

Looking at the parts fisch, it appears 4 anodes ARE under the heads.

Sounds like the lack of progress and shoddy work, it's not a bad idea to clean the cooling passages, check replace thermostat, a general going over...

R&R the heads isn't difficult, lots of salt build up is time consuming to clean. Should be around $100 in gaskets...

The engine is 31 years old. Salt build up would be expected and would definitely cause temp / overheat issues... Properly maintained, (cooling passages cleaned, new WP, etc, should get temps regular and even). We also don't know how / if one side is running hotter/how it was measured, etc...

For the OP, do you know if in-deed anything (or what) was done to the block/crank, etc?

Hi
Thank you for the reponce(s) .
Originally the oil pump failed . I did not get
any details from the company that did the work .
I said go through it and rebuild it . I was so disgusted
with what I found I was scared to really use it . The reason
I wanted a so called professional do the work , I wanted
confidence when I am out . I asked the guy "did you replace the anodes?"
Answer : "didn't know you ran it in salt water" (insert swear word here)

The boat had sat for 3 years until this spring . I have to use it or
Get rid of it , thought . I started using it this again . It does run really nice .
This spring I got a overheat alarm . I pulled the thermostats .
Boiled them , they seemed ok . I have been Leary of it
Overheating. When I was rinsing it out after a trip . I felt the heads .
One was much hot than the other . Anothe time When I was running it on muffs
a few weeks ago , I measured temp with a infrared thermometer. One side was 78 the other was 175 . . I've noticed a lot of flaking around the gaskets (head and water jackets) this is why I want to take it down .
Those head bolts are not that long I suppose..? They will come out before hitting the cowl ?
How would one get the proper torque when reinstalling?
I bought the gaskets , t stats , and anodes . Will I need much else ?
It needs doing !
Thank you guys for the help .

Ok, makes sense... The much higher temp on one side, if it was salted up, I'd say that was likely the cause. That is IF he cleaned them...

Your engine has a pressure control valve (PCV), (part #35 in the above parts fisch) for low speed operation to keep water up in the block at slow speeds. That failing would lead to low speed overheating. If it's old, it's also likely toast and helping with that problem..

Obviously, sitting that long(even if not used), I'd replace the impeller as it probably has a "set".

The last V6 200 yamaha we (neighbor and I) pulled the heads on(salt build up-same procedure), the bolts aren't that long, especially once the head is loose and shouldn't be a problem.. The heads had the torque sequence imprinted on them and of course you should torque down in steps(we did 4 or 5 vs 3). I got to every bolt head with the torque wrench one way or another (so there was no guessing)

You should invest in a shop manual. The head bolt torque would be in there. It may, be imprinted on the head as well.

Zoom in on the parts fisch. You can see the head bolts and get an idea their lenth and everything else you'll encounter... If a bolt doesn't want to loosen 'easily", forcing it will bust it off. Use penetrating oil, maybe some taps on the bolt, heat, etc. Get too anxious and you'll be at the machine shop or doing more work than need be. If he was actually in the engine, those bolts shouldn't be an issue at all...

Thank you for the quick response!!
So I am on the right track then .
The part no 13 shows just a bolt . ..?
I googled the part no. And I Just get a bolt ?

I have done absolutely everything to keep this in
Tip top shape . I.E. Water pump whole thing ,grease, plugs ,
Change lower unit , water separator change . I believe
In high maintenance!!
When I go out I want to relax not worry .

You are in Connecticut? I realize there is a coastline there but very different than what many of us are used to.

[Guttsetlk115]

Ha ha !
Yes we have Long Island Sound , ive heard it referred
To as the "toilet"
😳

Part # 11, (4 of em, are the anodes), NOT part #13...


(Look down the right side of the parts/prices. It's almost easier to find the part there, zoom in on the pic and see where it goes.)

Apparently you have rocks as well. Tend to make me clinch up tight.
