120 Force - Tilt / Trim issue?
I have a 1995 Force (by Merc) 120 hp outboard with power tilt and trim. A few years ago we had new carpet and upholstery put in the boat and the guys that did the work had to disconnect all of the wiring to do the work, but then could not figure out how to reconnect it correctly. I swear, before this I could trim/tilt the motor to any position and power the boat onto the trailer. Now when I throttle up, the motor will drop all the way (bottom out on the bracket) or run the prop into the ramp.
The power trim works fine and holds the motor in place if it's at a normal run position and under a load and the tilt works fine to raise and lower the motor when installing the transom saver. Is this normal, an electrical issue, or a tilt issue? |

Re: 30 Year Boat Yard Owner / Technician
There were a few variations of the tilt and trim on this particular engine.
Some were equipped with tilt only, which would not hold the engine up under power, but would lower when any more than an idle power was used. This system is easiest identified by only having one hydraulic cylinder under the engine. Give me your serial number and I will attempt to get a straight up answer for you. A picture would be quit helpful also. I don't believe you are describing a electrical issue. And I would further think not if the up and down trim switch is confirmed as working as designed, and the electric motor of the trim system is not running when the throttle lever is pushed forward. I did have a trim wire being pinched against a power wire one time when the throttle was being moved forward. We can test for this by turning the key to the ON position, not running the motor, manually shift the engine into gear and advancing the throttle. Does the electric trim motor start running? Then wiggle the wires under the shifter and see if this gives us the event we are looking for. Likely, if your engine has only one cylinder under the engine transom bracket, and not the short "Stubby" trim ram, the unit is reacting as designed. Hope this helps,...Get me the serial number and a picture and I can better guide you. Dominick

Re: 30 Year Boat Yard Owner / Technician
As for the Throttle moving on it's own, there is a adjustment for "friction" on the control. Shoot me a picture of the control assembly and I will tell you how to add a little friction to the handle.
I am looking into the tilt system.....Back in a few....

Re: 30 Year Boat Yard Owner / Technician
I just looked up this unit and indeed it is Tilt and "Trim", The hydraulic system should hold the motor in the position selected and left at.
As I indicated before the wiring could be at fault in the sense that it could be powering the unit down when your moving the handle forward or inadvertently touching the down trim switch. Otherwise the hydraulic unit has an internal leak allowing it move under pressure. A sure fire way to find if the issue is in the wiring or the Hydraulic assembly, would be to set the engine at a trim level, say 10 degrees, disconnect the power wires to the pump motor and see if the unit pushes down. Hope this helps and it should find where the issue is. In the wiring or the hydraulic unit.

Re: 30 Year Boat Yard Owner / Technician
Follow the wires from the pump motor under the engine into the cowl, then a wire connection will be found. Simply unplug it.
The friction control for this control box (according to the repair manual) is just under the bottom of the shift handle. It may be necessary to remove the upper and lower "clam" covers to gain access to the slotted screw. Tighten a little at a time to increase the friction of the handle.

Re: 30 Year Boat Yard Owner / Technician
Chef Al,
Sorry it took so long to get back with you.... If you still need assistance. Take the cowling off the powerhead, on the starboard side of the engine you will find the throttle advance linkages. Have a friend move the throttle lever and what you are looking for is the idle stop screw adjustment. It should move off the block whenever the throttle handle is moved off the neutral position. Move it several times to locate this adjustment screw. Loosen the jam nut and turn the screw clockwise to advance the idle setting. The thing to look for is to not jam the control cable when returning to an idle and to make sure the idle stop screw contacts the block every time the throttle is advanced and returned to idle. This cable adjustment is done with the knob made onto the control cable itself which is located in the bottom of the cowl starboard side of the engine. Hope this helps. I must say that generally the idle will not move out of adjustment without some other issue developing. Like carburetors are fouled, water in fuel, Ect. Idle adjustment should not be used to mask another issue. Your engine mixes the oil with the fuel before the carburetors, if the carburetor is not allowing enough fuel to the engine, it's not allowing enough oil either. Let me know what you think,.... If want to call me, pm me your phone number

Re: 30 Year Boat Yard Owner / Technician
Thanks! I'll clean the carbs but this has been an issue since I bought the boat (very used) several years ago. Yes there has been water in fuel--cleaned and taken care of. Yes the carbs need a clean--so--that being known, I'll do those FIRST and then adjust idle if need be. More hands have been on this motor than an exotic dancer looking for dollar bills,,,so who knows whats been done to it.
I'll report back when done.

Re: 30 Year Boat Yard Owner / Technician
Appreciate to offer here to help/answer.
I have a 2005 Yamaha 90, 300 hours, garage kept and pretty much babied. Last Service was 2 years ago(260 hours) and it was the routine seasonal service, no problems. Two outings ago the trim began fast but then slowed to a crawl last few seconds of raising the motor only. Thought it was battery, checked, OK. (I am no mechanic), next outing the trim did the same, but now up and down. I tried the trim at the motor and the trim at the throttle, both doing the same. Last outing the trim completely stopped after the first few seconds of use, both up and down, but resumed after a few minutes rest. I know I need a mechanic, but what can I check? Thanks |
