    No spark 90 hp 1999 Force after switchbox replacement

    The trigger and coils rarely go bad on these motors. The Amphenol connectors do go bad. They get hot and loose contact. The coil in some cases can go bad but not all 4 at once. I've not seen a trigger go bad for a LONG time. In 95 they went from Force/Prestolite to Mercury ignition. In some...

    Force 75 threw a magnet at us

    If the tach is the wrong or bad it can cause a no spark situation.

    No spark 90 hp 1999 Force after switchbox replacement

    outboardignitiondotcom has test procedures for your motor, you can do the basic tests with a regular analog meter but the more technical you'll need a peak reading/DVA volt meter. pnwboat said the reg wouldn't stop the spark. But it can." from O.I. Disconnect the yellow wires from the...

    Force 75 threw a magnet at us

    My opinion: Seafoam's a waste of $$ I use Chevron with Techron. Black bottle, looks like an upside down funnel. Mix it with 1/2 gal gas. and run through the system. The primer has a diaphragm inside and it can leak fuel into the carb and cause poor running at all speeds. Once it's running...

    Fuel Filter

    Before the pump makes the pump work harder. Most older boats by now have a water separating filter(or should have) and that catches the big stuff. The same with the settlement bowl and the filter on the other pump.

    90 compression on 135 hp

    The HF gives results just not the right results. The good is all cyl. are the same and that shows they're probably ok.

    Starter engages the flywheel but won't spin the engine

    The one you have is easy to rebuild. The Sierra ones are the latest Chinese JUNK!!(and not the boat) If you want a rebuilt one?? ARCO starters are the only way to go. They're a US company and have good quality. A little expensive but you get what you pay for. But from the looks of your starter...

    Force 75 threw a magnet at us

    They're gold because they only used them for a limited time. The older Prestolite ones were used for 10-12 years and millions were used on the different Chryslers and Forces. They fit 50hp 85/90 120/125 and 150hp. Yours fits a bunch of motors from Force to Mercury, to Sport jet, Mariner etc. I...

    Carbs leaking fuel 1988 force 125hp

    The sneeze is ok as long as it isn't backfiring. Backfiring can blow the port cover gaskets. That will allow the motor to suck air and cause major problems. Once it starts, do the starting fluid test, spray SF around the intake side, under the coils/packs and bases of the carbs. If that makes...

    Fuel Filter

    I install small particle filters between the pump and the carbs. Fram G2 G3 G12 These are see through and easily changed. One of those will work depending on the hose size. The newer Forces from 94 up should have one from the factory.

    Force 75 threw a magnet at us

    If the magnets(even one) come loose?? then the rest are probably gonna follow :( The flywheels are rare and pretty expensive. Fact: you'll probably find a complete motor for the price of a used flywheel. Saw one on FB Marketplace for $550 new they're 600+ The flywheel fits a LOT of different...

    Starter engages the flywheel but won't spin the engine

    Just rebuild/clean the starter you have. Double check the battery cable for weak/soft spots. Bad grounds. Those part#s are hard to look up. Post a pic?

    90 compression on 135 hp

    The temp shouldn't make any difference. The 90# is low but that could be the way the test was performed or the gauge used?? But 90 on all 4 is good. With a different gauge you'll probably see better results. Harbor Freight or any tools made in China will probably give bad results. I was selling...

    1983 Chrysler Sea King 15 hp startup after rebuilding

    Since you've had the head off, you know where the cooling passages are. Run it in the lake and check the temp where the cooling passages are. Right around the spark plug of course will be the hottest, but at the cooling passages it should be closer to the temp of the water. I've heard if your...

    Starter engages the flywheel but won't spin the engine

    If the starter engages but doesn't turn the motor, that doesn't sound like a solenoid problem :( My first guess is the starter is bad?? take it apart and check the brushes??? My second guess is the connections are bad?? check the grounds and the battery cable for loose or swelled cable??? #3 is...
