    1995 Force 120 will no longer idle

    Fuel pump can be new and still be bad?? The primer/choke: it has a rubber diaphragm inside that can puncture and feed fuel unrestricted making the idle problem. I believe if you pinch off the hose from the primer to the base of the carb that will show if the primer's gone bad??? You try the...

    Force 120hp Major Overheat

    It's gonna be a pain but pre mounting to see if the gasket/rubber seal fits right might show the problem??

    1995 Force 120 will no longer idle

    No idle: fuel pump diaphragm, sucking air somewhere. Sucking air: Try this: start the motor and spray starting fluid around the intake side of the motor. This includes the area under the coils/packs, at the carb bases. If the spray makes the motor run differently then it's sucking air. The 4...

    Picked up a 1990 Force 50HP yesterday.

    The float bowl will show what condition the rest of the carb is in. If?? it's real dirty and corroded?? Then the jets and other parts will be that way too. Most times the spray cleaners work just fine.

    Picked up a 1990 Force 50HP yesterday.

    If you buy the regular ones?? Then use duct tape to seal the edges. The tape needs to be put on before the motor gets wet as it won't stick very good.

    Picked up a 1990 Force 50HP yesterday.

    (Three hours later I went in and told him it was done. Paint was shiny, Vinyl top was white. Looked like a grandma's car. With some timing adjustments, it was the strongest stock 318, I've ever run. A couple years later, I ended up giving it to one of my brothers after I picked up a 78 nova...

    Picked up a 1990 Force 50HP yesterday.

    Back before I started working on anything(cars, boats etc.) I had a 15ft. trihull with a late 70's 85hp Mercury. I decided to go up to a bigger boat. Bought a 31ft.cabin cruiser. The 85Mercury ran good and then started to get hard to start. Sold it to a guy who insisted to start it. I turned the...

    tg3690, shame on you. Don't rain on his parade, he's just getting started. :) Metalchewy: you bought a good motor, they will last a long time, just use a good oil and keep up the maintenance. That motor needs a special set of muffs for running off the hose. That motor can run on 1 cyl. and run...

    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...
