correct also sounds like you need to up your idle been rebuilding my 125 with the same setup at that idle speed your motor will die every time in the water the idle is going to be high when your out of the water.
where the large alloy plate hits the roller is the problem. get a small piece of clear hose and put it on the roller, to me this looks like your old piece has gone rotted away etc.. this will put everything right and give you full throttle and better timing per throttle..
No, that roller is factory. When I run into that problem the usual fix is to advance initial timing. Most mechanics ignore the spec's on an older motor - only max advance is critical on a 2-stroke anyway. Two-stroke motors aren't designed to idle so often initial "advance" is AFTER TDC so it'll run slow.
You have to adjust the linkages for the same reason you need to adjust your bicycle’s shift cables..... because they stretch over time. My ‘95 Force 90hp was impossible to drive slowly because it wasn’t synchronized and the gears would grind unless you were at 1/4 throttle. I don’t remember the procedure but it’s on iboats and it was a simple job to get everything back to spec. Took me 30 minutes.
We have a ,9hp force engine we were told the stator was bad so we replaced it. Cleaned and drained fuel lines now the boat starts runs good til you put in the water . Then it runs like cr_p. & dies .have any suggestions. We checked one of the carborators floats thaught maybe they were sticking, it floated. Help plz Kathy
Kathy Froehmer I agree mine ran great in a barrel out in the water the motor would buck like crazy carb was nasty had to completely rebuild it Including taking the Welch plugs out
hey man did you get it I have the very Damm exact issue right now been on it for 5 hour's!! if I make the adjustments for the crab to open all the way up at wot then I idle to high ..I don't get what i did wrong ..I just service the carbs so it must be some thing I did ..help me out please
I have a 1989 85 hp force outboard motor. the last time I had it out the gas tank somehow got sand in it. I cleaned the fuel pump out cleaned carburetors and blew out the fuel lines. and now it will not stay running. it runs great out of water but as soon as it's in water it stalls and runs like shit. I'm about to scrap this piece of shit motor.
if your boat bottomed out you may have sand or dirt in your in your bottom unit and telltale flush bouth with hose do not start motor use water hose nozzles to flush telltale and bottom unit if thats not the problem you may need to replace your seals in the lower unit
Have a 98 120 Force. High idles like crazy and misses. Won’t idle right. Cleaned carbs, rebuilt fuel pump twice with gasket kit. Anyone have ideas? In water it won’t go past 32 mph and then shuts off. Pump bulb and it will start but misses and then does same thing.
@@its_Kris I actually bought a trigger assembly, was about $80 and that fixed the problem (have to re adjust afterwards). Take a pic of where your trigger arm is adjusted to, its the silver flat nosed adjuster right under the flywheel.
turn the screw where you have your screw driver wedged that is a cam and will press tighter or looser on the throttle

might also have a look at your power reeds
How did this thing do with the boysen reeds? It make a noticeable difference?
Who made those engine cover says Force inside us marine but it looks like a chrysler

Did u get this resolved?
Jitom7 yes. Took off the high compression cylinder head, and swapped out the powerhead from ported, to stock ports. Purrs like a kitten now.
For the future don't fuck with the linkages . Never

bad seals in lower unit
youtub how to replace
What rpm are you looking for at idle ? I know WOT is 5500 rpm on the 90hp but I can’t find the idle range in the manual.

Daniel Saucedo yes, put it all. Ack to stock haha. No more high compression cylinder head and stock rather than raised exhaust ports
bad seals in lower unit
youtub how to replase
having a simular problem cant wot no matter what i do 1994 sport jet 90
Sounds like your exhaust is obstructed with something. Too much back pressure when it's in the water but runs fine on the muffs

You probably smoked the cylinder bores with that grit.
if your boat bottomed out you may have sand or dirt in your in your bottom unit and telltale flush bouth with hose do not start motor use water hose nozzles to flush telltale and bottom unit if thats not the problem you may need to replace your seals in the lower unit

check ignition coils? took me maybe two weeks to figure I was only running on 3 cylinders

High idle from vacuum leaks possible
Our 90hp force runs great till you put the propeller in the water then it bolks down and acts like its not going to run
Your idle mixture is probably too lean. Give all the carbs a half turn out. She needs a bit more fuel to run under load at low speed.
Mine does same thanks for info
the sales in your out drive may be bad
@@haroldmurray24 the sales? i have this problem too.
I had this problem and it turned out one cylinder was not firing correctly so it only had problems in water. Had to replace coil pack on mine.
