Suzuki Tilt Limiter Cam.....

Just a FYI:
After boating on Tuesday evening, I came into my boathouse and tied up the boat. When I tried to raise the engine, nothing. I used both of the trim buttons, the one on the engine and the one on the control handle. It would go down, but it would not come up. A bit of panic on my part because the tide was going out and my boat goes dry on low tides. It was now dark, the wind was up, and no where to go. Long story short. If the tilt limiter cam (the black plastic ring around the swivel bracket in the picture) moves to the full up position, the motor will not raise. The feature is designed to limit the tilt of the engine in case the engine hits the motor well in the full up position. Who would guess that it could limit ANY upward movement of the engine? I talked to three outboard mechanics, and they all thought the problem was in a relay. The forth mentioned the limiter cam right off. I rotated it downward, and the motor lifted up, much to my relief. I am not sure what moved the cam. I suspect the control cables may come into contact with the cam at some point, or it may have vibrated enough to move. Don't know for sure, but now I know how fix the problem. Robbi
 
Another situation with the Suzuki cams- if they are adjusted differently, the motors in a two engine boat will rise to different heights in the fully "up" position. Drove me nuts until I figured it out.
 
And another thing...if you adjust it so the engine lifts up just barely far enough for the tilt support lever to engage, DO NOT drop the engine onto the tilt support lever, because the tilt limiter cam will prevent you from lifting the engine OFF the tilt support lever. It won't move at all. So then ya gotta reach under there and readjust the cam, so you might as well not have adjusted it in the first place.

In my case, it's pretty difficult to find a spot that allows the full range of movement I need to engage the tilt support lever AND prevents the hydraulics from straining when the full range of motion has been reached.

I have a Suzuki-manufactured, Johnson-branded 90 hp engine from 2005.
 
Hi gentlemen,
Sorry to ping an old thread but today I splashed Napoleon and my port engine will not trim all the way up. It goes up and down fine to this point then stops. My starboard engine goes all the way up as usual.

Where do I find the mechanism that regulates the trim level? I've never touched it on purpose but want to start there.

Thanks!
 
the main cause of the problem is salt crust build up around the cam limit switch. you have to spray with fresh water around the switch which is under the motor body inside of the motor mount. you cant see it unless the motor is up on most boats. and you cant get the motor up unless its clean.
 
The trim limited cam on my 90 is located right
Below the bracket where the steering arm is
Attached, in the center of swivel bracket. It is a black
Plastic ring that is in the center of the bracket.

I will try and post a picture.

Here is a picture of the trim limiter cam on my 2004 Suzuki 90. It is located on the front of the engine and this picture was taken with the engine in the full down position. The steering arm is directly above, surrounded by all of the necessary grease. :oops:

You can change the tilt by rotating the black plastic ring on the cam.

Thanks for the replies. Perhaps I accidentally bumped it when installing the new steering system this winter. I will check it out again today. My shop manual has a picture but it's very small.
 
I had the same type of problem on my 2005 Yamaha 90. The ring with the cam is plastic and actually broke. It was somewhat difficult to replace, so I just wired it together with stainless steel wire. Hasn't failed yet! (This is the only problem I've had with the Yamaha in 6 years!)

Joe. :teeth :thup
 
Thanks for the replies. It can very easily be bumped and I must have done it when installing the new steering system.

It is a small plastic piece that rotates very easily - like turning the knob on a car stereo. Took 2 seconds once I knew what to look for and voila - lifts to the usual spot.
 
One other thing: Make sure you get it adjusted so the trim/tilt hydraulics STOP PUSHING before it reaches the mechanical limit of the engine's travel, whatever that happens to be. It can put a lot of torque on things if it's still pushing when there ain't no place left to go!
