Probably a stupid question!

[hanksvilleman]

I just acquired a 1993 Yamaha 40 HP outboard, Model C40MSHR which has been sitting a while. I am used to bringing these older motors back to life and I have heard this one run. It needs carb cleaning and retested.
OK, now the stupid question. I know how to lock it into place for roading, but how do I lock it into the down position for when I'm in the water? Reverse won't be much good if the motor lifts out of the water because it's not locked into place.
I have searched and can't find what I need. Please help.
Thanks, Dave

Outboard Owners Manuals

I know it does not go back to 1993 but maybe the 98 manual will give you some clue.
the other motors I have had that were manual tilt used the same lever to lock the motor in the up or down position

My 1999 C40TLRX manual says not to use the tilt lock in the up position for trailering, get a transom saver/support device if not enough clearance while in the down position, but it is a power tilt and trim

I have a 94 30 HP There are 2 levers on it. The one on the right if you are sitting in the boat looking aft, I usually depress while in the water underway. It will allow the unit to kick up in case I run aground. I run on the eastern shore of Virginia and the sandy bottom always is changing and you never know when you may come across a sandbar. The unit will return to its original position (whatever set of holes you have your stationary bar set to) on its own. However if you put it in reverse you need to return the right lever to the up position to lock the unit in place. The left lever when depressed sets a bracket in place that will sit on the same stationary bar mentioned above. What this does is allows you to pull the motor up and run it at a raised position in case you need to raise up for shallow water. The raised position is determined by what set of holes you have the stationary bar in. hope this helps

Missing parts or made that way?

I must have some parts missing because I don't have a lever on the right side to lock or unlock the transom. But, one thing I noticed is that this motor also is regulated to a lower rpm in reverse.
Could it be possible that the motor wasn't made with the lock and is regulated to not throttle up far enough to lift out of the water? I think that would be a design flaw due to emergency situations, but I don't get paid enough to make those assumtions.
Thanks for the input,
Dave

What is in yamaha which not in other brand?

Because where planning to buy a motor vehicle. Other may say that Yamaha so far is good.

[hanksvilleman]

I'm not particular to any specific outboard motor. What really matters when you are looking for a motor to buy is what the compression is on each cylinder and the fact that the lower unit shifts without noises and easily. Everything else is realatively cheap to fix or replace
I have a Mariner 60 hp bigfoot on my pontoon boat and this Yamaha 40 hp is for my 16' fiberglass boat. A motor is only as good as you treat it, so cosmetic issues do play a factor when looking at a motor.

Never heard of anything like that before

[hanksvilleman]

I never have seen anything like it before either, but I stuck the motor into a tank and ran it. Just to test it, I shifted into reverse and reved it up. The motor did not lift but the motor has plenty of power The only thing holding the motor down is its own weight. It still has me puzzled. It is a short shaft and maybe that makes the difference with the lack of leverage.
I plan on taking the boat to the lake within a few weeks and I'll see what it does in a real life situation.

my 00 yammy 4hp doesn't lock in the fwd gear...

it's meant as a safety incase you hit a submerged object...
the motor will bounce up(backwards) rather then stay locked in place
it reduces damage to the motor/boat...

the force/propulsion keeps the motor down when in fwd gear, it only locks when it's in reverse...

not sure if it's the case with yours...
