    85 hp compression

    From factory the compression was 140-150 PSI. 120 and pretty equal on all, not more then 10-15% in difference are acceptable. The value depends on how good compression tester you are using. But 120 PSI is good enough to run with.

    1988 50 hp force no spark?

    The stator for your engine should be 300-888793. Crowley Marine maybe have for 587 dollar, uuuuhhhh! Outboardignition.com has it for 320 dollar, aftermarket CDI Electronics. Not cheap either.

    Bizarre starter behavior (won't "bench test" on motor)

    If you pull the starter from the engine again and "bench test", does it run then? Something must have happened when you mounted the starter at the engine block. Worn brushers or bad brush springs, dirty commutator etc. But you says it is a brand new starter. If you connect positive wire from...

    Bizarre starter behavior (won't "bench test" on motor)

    When you jump start on the engine, where do you connect the negativ wire? Positive wire at the terminal at the starter and where do you connect the negative? At the starter housing or at the engine block or where? If you ground (negative wire) at the housing and the positive wire at the starter...

    1980 chryler 85hp charger tach replacement

    Is the factory ignition system the battery driven Magna Power system with a distributor or the Prestolite CDI ignition without a distributor? If the first one type of ignition system with a distributor you need to count how many poles the stator has. I think it has 20 or 12 poles then you have...

    Won’t stay running 125 force pestoline

    Yes you have to explain. "The tdc mark stays relatively close to the main timing marker" TDC is the zero (0) mark, to the left of the zero mark at the flywheel there are three marks. First left is 28dgr then 30dgr and the last one 32dgr BTDC. You adjust the timing at WOT and set it to 28dgr...

    Won’t stay running 125 force pestoline

    Yes it is. The range of the multimeter tells you how high values it will manage at the range you have choose. If you got 164 and 154VDC with the DVA adapter the stator suppose to be bad. You should have 210VDC or higher at cranking speed.

    Won’t stay running 125 force pestoline

    You have to use a DVA adapter to measure voltage right when troubleshoot CDI ignition systems. A DVA adapter is a single wave rectifier with an electrolytic capacitor and you use it because your are not able to read the peak voltage with a VOM. The DVA adapter rectify the AC voltage in to DC...

    1972 Evinrude 40 outboard no spark?

    Ignition coils, condensers and points are under the flywheel. If no spark with the remote unhooked pull the flywheel and check. The ignition coils at these OMC engines have tendens to dry out in the insulation. You would see it if they are rotten when you have pull the flywheel. Clean the points...

    85hp 3 cylinder Force carburetor throttle plates.

    DunbarLtd: I think jerry mean that the throttle butterflies need to equal at idle. A little difference at WOT do not have any affect for the performance. As I mention before the last degrees at WOT to horizontal have very little affect. Gica: Yes the three carb engines has a tie bar same as the...

    85hp 3 cylinder Force carburetor throttle plates.

    If the throttle butterflies are not equal horisontal at WOT, sync them at WOT. Set remote control at WOT and loose the screw at throttle rod that connect the butterflies at not horisontal carb and sync it. Check how the butterflies are at idle, they should be equal to each other. You adjust the...

    Chrysler 75hp, need direction.

    Look at the throttle cam curve and you see how it is shaped. As topgun says, that is pretty much how it is.

    Not sure if something broke

    Yes, some of the impeller housing has that white plastic tube some does not have it. They have a rubber grommet. If I remember right larger Chrysler has the white plastic tube and Force has a grommet. What engine are you dealing with? I see it has the two piece drive shaft so it must be a Force...

    Force 120hp won't start

    Starter disengaging when engine takes over is normal and it should do that. Your issue is that the engine do not start and run, just want to but do not. Something is wrong with the timing/throttle tune, but I can not right know figure it out. If you have done the link and sync by Frank A it...

    1990 Force 120HP carbs mix adjustment help

    As you says you can not change HT wires. I am in Sweden Europe but here you can buy spark plug boots that you screw in to the wire. Cut the end of the wire and change boot or clean the OEM boot spring and pierce it in to the wire.

    1987 Force 125 tower shaft linkage frozen/seized

    Check out your throttle pick up point adjustment and throttle rod adjustment. You should have a little play to advance the throttle when starting. In the pic it is to tight.

    Johnson 4HP questions

    Do as Jimmbo says check compression and check for spark. The spark should jump at least 1/4 in in atmosphere. The ignition coils for these old OMC engines had a tendency to crack over time and dry out. They can create spark but when under load it will fail. Pull the flywheel and check those coils.

    Short vs Long Shaft for 4hp

    OMC smal OB 60-70.es has an extension part for the long shaft. Easy to see, different between short and long shaft is 5 in. Short shaft 15 in long shaft 20 in. You measure from transom clamp to anti cavitation plate.

    Milky fuel in carb intake force 85hp

    Main jet for sea level-2500 FT should be 0,074. 2500-5000 FT should be 0,072. It will not run well with a too small main jet. I do not know if this have anything to do with your issue, but it will run lean with a 0,072 at lower sea level. Think your main issue is water intrusion in 3 and 4 cylinder.
