    OMC exhaust flapper alternative.

    Just google Barr manifolds. They do have riser extensions but only for Mercruiser style rear riser. The exhaust hoses are easy to adapt.

    OMC exhaust flapper alternative.

    Were they OMC parts? The only other thing I can think of center rise manifolds with extensions. Not cheap but should solve the problem.

    What else will bolt up to Volvo 270 outdrives?

    A 3.0 liter engine will work but you will need an adapter plate made to bolt the Chevy to the Volvo pattern. The Volvo flex plate will bolt on to the Chevy flywheel with the same thickness spacer that the adapter plate has. Also the front of the pdf shaft has a small extension that centers in...

    MC-1 bellows clamp preferred locations

    My bad on the socket size, 5/16” quarter drive is the correct tool. Also the shift cable boot clamp looks up next to the inner wall of the transom plate.

    MC-1 bellows clamp preferred locations

    You need a 1/4” universal socket and some 1/4” drive extensions with a driver handle. The drive shaft bellows clamp should be a 1;30-2 o’clock on the starboard side of the transom plate. On the bell housing side the bellows clamp usually is at 3 o’clock on the port side above the water hose and...

    aq115 oil and water mixing

    Make sure that someone did not block off the weep hole on the water pump, if the seals in the pump leak I have seen that happen when someone thinks that is the cure. It lets water get into the timing cover.

    Alpha One Gen 2 impeller delete question

    Mercruiser also recommends using the drive pump along with the crankshaft driven pump when pulling water from the bottom and connecting them with a “Y” pipe setup. Since there is a sea valve you can shut it if you want to run the boat on a flush out.

    1989 OMC Ford 2.3L finding cylinder #1 on Mallory (YS621CV) Distributor Cap

    It does not matter as long as the rotor lines up with whatever spark plug wire going to the #1 cylinder when the #1 piston is at tdc firing position and the timing mark on the harmonic balancer line up with the “0” mark of the tab of the timing gear cover.

    Seriously stuck gimbal bearing

    2Xs with Chris’ slide hammer. I have the exact one like his. And I have pounded myself to exhaustion also. If the bearing is that corroded then water has to be the cause. The bellows must be changed. You need to remove the bell housing to give yourself more working room. Carefully drilling...

    Omc 5.7 cobra. 1992 sunbird.

    You need to replace the points and condenser. Once points act as your‘s are doing it will never run. Filing the points might help but in most cases only temporary. You probably have a Prestolite distributor. NAPA will have them.

    My OMC, 305 V8 stinger has a Prop Lyft problem

    The glass fuse holder that provides current to the tilt/trim solenoids can cause a problem. The fuse holders tend to loosen up and may be the reason. Remove the fuse and pinch the holder on both ends to give the fuse a better contact and also replace the fuse with a new 50 amp one. Or go to a...

    Need Penta AQ125a Carb -1983 Bayliner

    Most times those carburetors can be disassembled, cleaned without needing any parts. Remove all the fittings and blow everything out with compressed air. Set the idle mixture 1.5 turns from lightly seated.
