    1988 force 50 HP cooling or water pump question.

    Re: 1988 force 50 HP cooling or water pump question. Torque sequence should be spiral sequence as shown below at 270 inch-lb (22.5 FT-LBS). The pic below is for 125HP but the sequence is the same. Make sure you do at least 2 or 3 step torquing, i.e. torque all bolts first with 90 in-lb and then...

    85 hp force tilt/trim removed is it ok to run the boat without it?

    Re: 85 hp force tilt/trim removed is it ok to run the boat without it? Usually, the transom clamp has holes in it to bolt down the motor in one permanent trim position. There are two ways to do this: With the trim cylinder out, the kingpin will lower itself all the way (trimmed in all the way)...

    Overhearing again

    Re: Overhearing again First thing to check is the exhaust cover to make sure there is no blockage and then the t-stat to make sure it is opening. Better yet, remove the t-stat and test again. Attached is the water flow diagram for a 4 cylinder engine although most cooling water flow is the same...

    1993 Force 150 tilt / trim repair

    Re: 1993 Force 150 tilt / trim repair Tommy, fully understood your explanation but to go one step further. Each relay has two separate ckts in it. The wire that connects directly from the hot side of the starter solenoid that connects to the T&T motor through a set of contacts (in the relay) is...

    '89 50hp Force Irratic idle and bad skip until runnig full throttle

    Re: '89 50hp Force Irratic idle and bad skip until runnig full throttle See attached pics how to set carb float. One important thing is to make sure the float lowest drop is even with the pick up tube as shown on Step 10 and should not rest or touch to it. A little higher would not hurt but a...

    Milky spark plugs

    Re: Milky spark plugs Based on your serial number you will use the "Torque and turn method" discussed above. However, your sequence should be the standard spiral sequence method (shown below except this is for a 4 cylinder engine but the sequencing should be the same. The one posted above is...

    89 Force 50HP turns on and stays on only on high idle start

    Re: 89 Force 50HP turns on and stays on only on high idle start I forgot to respond to your torquing question. This is how I see it. Remember, the torque requirements are in inch-pounds, thus you should use an appropriate torque wrench range (required torque should be within 20-80 percent of...

    89 Force 50HP turns on and stays on only on high idle start

    Re: 89 Force 50HP turns on and stays on only on high idle start From the sound of the engine it is misfiring and probably only running on one cylinder as indicated by the clean spark plug. Double check both plugs to make sure they both have sparks in them using a spark tester. This is the main...

    Force 125 tilt/trim pump bypass valve

    Re: Force 125 tilt/trim pump bypass valve Have you tried using compressED air with a blow gun nozzle to blow into the valve body to push the spool valves? Here's a pic of the valve body where you will direct the high pressure air. I marked three holes but only two actually works but I cannot...

    Force 125 tilt/trim pump bypass valve

    Re: Force 125 tilt/trim pump bypass valve Actually, you do not need to dismount the whole motor-pump assembly but you will need to drain the oil and disconnect tubings (you might have to loosen the motor/pump housing unit to do this and avoid cross threading the fittings). And then dismount...

    Force 125 tilt/trim pump bypass valve

    Re: Force 125 tilt/trim pump bypass valve I wish you had provided a picture of the part(s) you are referring to. But if what you are referring to is the removal of the spool valves themselves (held in place by C clips in your case as you mentioned) the best way is to use air pressure with a...

    Force 125 tilt/trim pump bypass valve

    Re: Force 125 tilt/trim pump bypass valve The following is a test procedure to determine which component is causing the leak down. You will need a 3/16” brass cap and also a 3/16” plug. Both are available at Ace Hardware or some auto stores. Step 1: Test the tilt cylinder for leak down 1. Raise...

    pump/tilt slowly lowers?..

    Re: pump/tilt slowly lowers?.. Check this thread and it should give you a very detailed info on how to fix your T&T lowering problem. The part I had a little difficulty is when opening the little valves where those little seat o-ring are located at. So I bought this clip pliers from HF making...

    1992 Force 50hp wiring diagram

    Re: 1992 Force 50hp wiring diagram Actually you are on the right track, matching the yellow/blk (knowing this is the choke wire from the old harness) to the green wire of the new motor. And you can verify this using a diagram as provided. Another match will be the white (from old harness) to...
