    OMC stringer thump sound from the rear.

    Try tightening the set screw in the tilt shaft. Also check all the engine mounting lag screws in the stringers. Is the propeller tight? It should not be able to slide on the shaft.

    Converting 260MIE RH to LH.

    OMC stringer thump sound from the rear.

    You should not be able to raise or lower the drive by hand. First try a 1/4 turn first, if it still wants to thump give it another 1/4 turn.

    OMC stringer thump sound from the rear.

    Volvo Penta AQ125/270 overheating raw water not pumping

    Try what I mentioned, by submerging the suction hose in a bucket of water or just stick a garden hose in it. If the pump does not pull water then I bet either the 1/2 moon key somehow slipped out or the pump drive coupler is not turning the pump shaft.

    Outdrive Popping

    He still had to remove the 2 rear vertical mounting bolts that Achris posted. As Scott also said the drive has to come off to set the shaft alignment. If it is not aligned the drive coupler aluminum splines or the rubber part will fail and leave you paddling.

    Volvo Penta 3.0 GLP Stalling when reducing from high RPM.

    The only other thing that I have seen cause this problem is the rotor in the distributor. What happens is as the boat is coming off plane it puts a load on the ignition and the high tension spark goes through the rotor to the distributor shaft.
