    T&T leakdown tests

    The old would have been good. The torques used in outboards is usually minimal and the screws haven't been streched or twisted. The only time I buy new is when the heads are rusted off.

    Force 85 really difficult to start

    I don't know the kind of tester you have?? Buy/ borrow a good one. But as long as all 3 are within 5# of each other you should be OK! Your results should be between 145-160# Harbor Freight tools are seriously lacking in results :( Was selling a 2002 Mercury 225 EFI The customer wanted a...

    Static timing is done with the plugs out and the wires grounded. I made a 3 wire octopus for grounding the plug wires. Timing marks L-R 28 30 32

    T&T leakdown tests

    Your one of the lucky ones!! That trim cyl. is almost NEVER taken apart without something breaking!!!! One rust spot: if there was moisture trapped in there?? it can rust and corrode the one spot.

    A few pics can tell what year your motor is? You have the sticker on the transom clamp?

    91 Force 40 runs rough

    They didn't make a 40hp in 91?? They were made in 92 Then 95-99 If it made a difference when sprayed under the pack/coils?? Then the port cover gaskets are probably bad. One little cough, backfire or stutter can blow the gasket :( I'd pull the covers and check the gaskets. I doubt you need to...

    1984 Force 85HP starter will not operate - all wiring appears to be correct

    Yes both points are the starter ground. Under the starter against the block is a ground lug that the battery cable is attached to. Check the ground and check the battery cable itself? Open up the starter and check for broken pieces?? The battery attachment point can break and cause the problem.

    Force 85 really difficult to start

    Look for the first 4-5 post in this forum. One will have the procedure called a "link and sync" That shows how to set the carbs up. The air screw is set at 1 turn out on the 87/85 Check the flywheel key. Do a compression test and spark check all 3 cyl.

    91 Force 40 runs rough

    Missing at idle usually means the low speed air screw needs adjusting or it's sucking air somewhere??? Do the starter fluid test: spray sf around the intake side of the motor, base of the carbs and under the coils and packs and around the fuel pump. If this makes any difference?? then it's got...

    1984 Force 85HP starter will not operate - all wiring appears to be correct

    The rectifier has nothing to do with starting, only charging.

    Chrysler 35 hp 1969,Suddenly no sparks at all

    You shouldn't be able to see sparks when you activate the choke. Possible your burning up the condensors when you short the solenoid?

    T&T leakdown tests

    Did you do the leakdown tests? The tests isolate and can pinpoint the problem.

    Force 85 really difficult to start

    From the color scheme it's an 87. You need to figure out the starting procedures??? #1 squeeze the ball until it gets hard, if it doesn't get hard, then the fuel pump might need a rebuild?? #2 throttle advance, depending on the shifter, you either pull the handle out and push it forward, or push...

    1984 Force 85HP starter will not operate - all wiring appears to be correct

    Some solenoid need to be grounded. The Force's I've seen have the ground wire on one of the lugs,

    New NGK BR8HS plugs improve overall performance

    Some motors can use any brand. Some just don't run right when you use NGK and others Champion?? I've had 2 88/85's that it didn't matter the plug??

    Force 125 lacking power

    If the air screws need to be almost all the way in?? You probably have an air leak somewhere? Do the starting fluid test and see if you can find it?
