    1998 force 120 tilt/trim not working right

    That year the T@T could be one of two styles, the symptoms are the same for both styles, post a pic ? The T@T fluid might be low??(maybe) or the seals in the pump might be bad??(maybe) The being able to lift it up the rest of the way shows low oil or bad seals. Lower the front of the boat...

    Beware the foam inside engine cover

    It happened to both my 1988 85hp ,otors and a bunch of others I've worked on. My solution? just remove it and run without it. I couldn't hardly tell the difference.

    Force 120hp Major Overheat

    Yup 1992 The stamp under the carb?? it isn't the best indicator, the best is the tag you posted and second would be the block. The tag says 1208F92C The c indicates a later run model. They A model used the Prestolite ignition. The C model was when they went to Mercury Ignition. The flywheel...

    Force 120hp Major Overheat

    Could be as early as 93 but looks newer 94+ Under the packs and coils on the block is a foundry stamp, the center of the stamp is the year it was cast, also under the bottom carb might be another foundry stamp. I'd bet if you get a snake camera and run it up along the water tube you'd find the...

    Force 120hp Major Overheat

    More info? year?? Pic of the pump, housing? IF??? the boat had set for a long time? the insects get up in the holes and make nests for their new young. Usually this gets blown out when the waters put to the motor, but in severe cases it won't. Snake camera: drop the lower unit and see if the...

    Hydraulic cylinder rebuild

    "If there are pumps on Ebay and they are Chines made, do not buy them! Starters for Chrysler/Force and made in China are crap, but cheap." Trouble is just about anything new is built in China. If it's rebuildable??? Then use OEM or Factory parts from a Mercury dealer. Those parts are probably...

    Hydraulic cylinder rebuild

    Hey Lou, Great job and the pics are great too. He's working on a Force T@T . The parts kits might still be around somewhere(E-Bay last I saw). And YES!!!! loosen the caps while still on the transom bracket. I found an O-ring kit from Harbor Freight, it just happened to have the right O-rings I...

    Can't open cover on a US Marine Force 50

    Spraying can make it harder to start. IF?? the plugs didn't have rust on them when you took them out, the cylinders should be ok. You can spray through the front of the carb to lube the bearings. Just don't overdo the spray. Initial startup: make sure the cavitation plate is at least 4"-6"...

    1986 85hp force 856X6L no spark

    You said: As far as the twins issue it was my fault I should have changed all the wiring in the electrical system because vibration will break anything that's old. I've found that the wiring connectors on the trigger/stator should be replaced as soon as you can. Some connectors have a shrink...

    Can't open cover on a US Marine Force 50

    The 80's 50hp. One of the better runners from Force/Chrysler. This motor runs on one cylinder almost as good as 2. Use good oil and replace the impeller. You do a compression test?

    Can't open cover on a US Marine Force 50

    Under the front of the cowling on the bottom should be a lever that moves that opens the cowl. #16

    71/72 105hp Propeller Clearance Issue

    When they went to the one piece lower unit they also changed the props. You'll need to find the older style for it to fit.

    Any advice on a starting battery and rectifier/regulator for a 1990 Force 120HP

    What I used: twin batteries both the same size. Minimum 450cca. I used 650 or 800cca even 1000cca. The bigger the longer they last when the boat has lots of 12v accessories #4 or #2 wire with good copper connectors. Using a deep cycle battery on an outboard can potentially cause issues with...
