    Installing new bellows

    Anything else I should know before I change the bellows in the omc cobra? I've read the manual and seems fairly straightforward: Coat the outer surface of the gimble bearing flange, watch for the grooves. Watch the positioning of the clamps mentioned in the manual. Anyone else have any tips...

    Impeller spun?!?!?!?

    You will need to split the upper and lower gear cases when it's off the transom mount. To figure out if something is cracked or a seal is gone. It's not terribly difficult to rebuild the lower part but I never touched the upper gearcase. You will need a couple specialized tools. I would first...

    Impeller spun?!?!?!?

    Not sure about a 4 banger like yours but if you look at your exhaust bellows theres a chance it comes slitted with holes (factory design) for what I assume is drainage. Have to trim all the way up. You might be able to see pieces of the exhaust flapper or they might have already be gone. Fairly...

    Impeller spun?!?!?!?

    I had the same experience with my omc, squeezing the muffs by hand. After discovering that I have always trailed it to a river or lake to test it. Pretty fortunate that it's only 5 minutes away. I don't trust muffs anymore. If you trim down at the boat launch before starting the engine in the...

    Impeller spun?!?!?!?

    Water is pulled up from the lower gear case, were the screens are just under the cavitation plate is. My screens were kind of falling a part, there's a chance yours might be gone completely if you are trying to look for a reference. The 1/4 tube is for either drainage or possibly a vent hose.

    Impeller spun?!?!?!?

    Not having the outboard/outdrive low enough in the water when starting the engine will do it. Also age of it. What are you running a stinger or cobra? My guess would be a cobra as it's the same impeller/housing as mine. They sit a lot higher in the water versus a mercruiser i/o or a outboard...

    A question on exhaust flaps 1989 Stern Drive 4.3 [ 432APRMED ]

    Just dropping the engine back into the boat after a rebuild, can't seem to find anywhere in the manual the position that the exhaust flaps should be in when OUT of the water sitting in the driveway. Mine are currently sitting in the full open position. Just wondering if this is correct or not or...

I have been slowly in the process of restoring the boat and have issue with the boat performing bad at high speeds, you are going to have to bare with me I don't know all the technical terms...
