    Coupler failure

    Normally, prop hub will fail first. Take to prop shop for testing. If you need to test coupler, lock up motor from spinning using best way. Make sure OD is in gear.

    TB 4 AND 5 COILS

    I ordered a coil for my carbureted TB5 MC Chevy V8. The ad read that it was for either ignition system for V8s and HEI. However, after examining the new coil, the positive side had 15 vt. listed. I am currently reading 12.25 volts coming from my ignition wire. I have always had 12 volts listed...

    Knocking noise at low idle

    don't know how old boat is or mounts' condition. You may want to check alignment, if you haven't already. Then buy cheap stethoscope and listen. You can feal U-joints for excessive wear and examine for rust. Obviously replace if bad. You can also feal roughness in the gimbal bearing.

    Boat ran great,stalled,now only runs a few seconds

    As ALLDODGE said... 12 volts at coil??? Ground plug to center coil wire and check for output spark. Then pull fuel filter and pickup tube. That old of a boat and sat for a while may have disintegrated rubber fuel line or varnish collected in tank.

    Alpha one gen one installing lower out drive

    I built a carriage to reduce weight on me as I moved OD spline into housing/coupler. I used 8"X 8" x2' wood. Old Railroad ties will work well to build up where you rest OD. You may have to shim for a better parallel fit. Then you slide od (not lift.) into housing. Obviously, you should remove...

    HELP! Outdrive stuck.

    U may have to wiggle OD spline into coupler, if it is not shifter keyway issue. However, if you changed gimbal bearing, insert alignment tool and keep forcing it into couple while beating tool side to side to center bearing inside housing.

    88' Mercruiser 165 harmonic sound

    Here is an old trick to determine if you have a bad plug. Get you some rubber gloves and pull each distributor plug wire at distributor while examining tack. You sure timing is correct? It may be advanced too much and causing pinging. Just an idea...

    Engine will spin up in RPMs boat hardly moves

    You may have to take prop to a good shop and pray it is defective. If not, lock motor from spinning, best way. Remove prop and replace lock nut with a couple of jam nuts. Using a breaker bar and proper socket, try turning prop shaft. Good luck.
