Re: 1987 force 125 h.p.

Leander: The tilt was never designed to be used at any speed. If you try to tilt the engine at more than about 1000 RPM, it just will not do it. There are relief valves in the pump and tilt cylinder to prevent excessive pressure and allow the engine to tilt up quickly then drop slowly if an underwater object is hit.

If you tilt the engine at idle and then hit the throttle, it will be pushed down onto the trim cylinder.

So, if you need to travel through shallow water with the engine tilted, it must be at no wake speed.

Re: 1987 force 125 h.p.

frank, i just went and checked the tilt&trim pump and found that there is another allen wrench nut on the back side of the pump.so i will remove the pump and motor and take that one out and see if it's the same as the front one. if it is, then i will replace the small o-ring on that one.

i took the pump off the boat and found the other allen nut on the back side of the pump. i removed this one and found that the small o-ring also was just about gone also. i will replace it and the other two o-rings and put the pump back on and see what we have then.thanks guys for all the help.

Re: 1987 force 125 h.p.

i replaced the small o-ring in the back of the pump.put the whole thing back on the motor and hooked up all the oil lines.they all went on with out cross threading. i then tride the pump and the motor went up fine. but it started down again. the oil line that comes straight up into the bottom of the pump started leaking oil. i tightened it up but that did'nt help.i went to a auto parts store and got a 3/8 to 3/8 brake line flare fitting bushing. put that on the pump and then the oil line. everthing went on fine but it is now still leaking oil.i'm at a dead end stand still. i need help, i don't want to have to buy a new pump after all the work i put into this one.

hi, i put z-weld around the outside of the two fittings and then coated it with j-b weld and a thick coat of seal all left it sit over night.then today i filled the pump back up and tried the tilt switch. the motor came up as nice as you please and as of now we no longer have any leaks.how long this will last,who knows. now i thank each and ever one of you for your help.now i'm out of here.

Re: 1987 force 125 h.p.

i put z-weld around the fitting and coated with seal-all and now we don't have any leaks.took the boat out and every thing works fine.the only problem that remains is the motor does'nt seem to have enough power to plain the boat out.seams like it should move the boat alot faster then it does at full throtal.

Try a 15 pitch prop. and I think you will notice a big difference that is if you don't already have one.
