    1995 Omc 302 replacement to 351 help

    There are some different weighted flywheels depending on wether the rear main is a full circle 1 piece seal or the earlier 2 piece. It appears that from 81 on Ford made the block with a full circle 1 piece seal. Try to find a 351 from a truck that has a manual transmission and from 96 on they...

    1995 Omc 302 replacement to 351 help

    The mounting points to the stringers are the same as well as the rear bolt pattern. Be sure to use a dual plane intake manifold and a real marine carburetor. Summit has both Holley and Edelbrock. The 351 has a larger oil pump drive rod than the 302 is why you need another distributor. If your...

    1995 Omc 302 replacement to 351 help

    If your current engine is fuel injected you will be a lot better off going back to a marine Holley carburetor and a standard marine distributor. You should be able to re connect the exhaust. I am not sure about the flywheel balance, the drive coupler should be no problem as well as the mounts...

    Starter help!!!!!! Omc cobra 4.3

    Are you using the original bolts. Are they metric or fractional. I am just curious as these engines could have either one. Which ever way you go you need about 3/4” of thread showing from the mounting surface on the starter.

    94 Volvo Penta duo pro C drive yoke

    There is a good chance the engine has to come out to replace the bearings in the adapter housing. Just hope that the drive shaft is not rusted into the flex plate on the flywheel.

    94 Volvo Penta duo pro C drive yoke

    There are some shims inside the seal sleeve. If you leave them out you will burn up the input bearings. They set the preload between the 2 bearings.

    I wonder if he is confusing the shift interrupter with the neutral switch in the control box.

    Need to tweak shift cable for reverse

    Does the slider travel all the way to the front wall of the bell housing? I have had problems with the grease building up inside the slider restricting full travel. With the cable disconnected from the control box does the drive go all the way into reverse by pulling the on the lower cable...

    Need to tweak shift cable for reverse

    Sometimes when reverse is the problem there is a build up of marine growth in the front cavity in the bell housing restricting the slider from moving enough. Also the same symptom going into forward where the same material builds up in the rear cavity in the drive shaft housing Restricting the...

    The flat large flange that contacts the suspension fork is retained with a bent over stainless washer that has to be folded down so that the flange will unscrew.

    Needing Wiring Assistance After Engine Swap

    If you look at the wire harness and plug where the engine connects to the boat harness to the Ford engine the colors will match. Like I previously mentioned it may be easier to just swap the Ford harness to the Chevy. I have done swaps like this before with all the stern drive engines and re...

    VP 280 Spline Splice Orientation

    The upper gear housing to the center section is sealed with “O” rings. There is also should be a shim in the bearing cavity. I cannot remember which way the sleeve goes but maybe the short side faces up.

    Needing Wiring Assistance After Engine Swap

    The pump in the Mercruiser drive will NOT have enough flow to cool a fresh water cooling system like this engine has. So be sure to set your engine up like I described.

    Needing Wiring Assistance After Engine Swap

    Sounds like you did good. Volvo use Prestolite distributors. If it still has points get a Petronics electronic conversion. If you want to eliminate any heating problems put a through hull sea suction directly to the suction side of the raw water pump and connect the incoming water line from...

    Needing Wiring Assistance After Engine Swap

    On the back of the instrument panel the oil pressure should be blue and the temperature wire should be brown. The tachometer should be gray. However I have seen this style of harness on the boat and it is a generic harness, non Mercruiser. The pink wire on the engine side is probably the...

    1993 Volvo Penta 570A New Distributor Issues

    With a Petronics conversion the 2 wires from the distributor if one is red and the other black then the red goes to the +side of the coil and the black goes to the -side. Disconnect the rev limiter and try that. Some Petronics are designed to operate without a resistor. Did your kit come with...
