    V4 - Minimize Chances of Broken Rings

    Prop / prop shaft damage

    I suspect that the Gearcase is low on Oil and the Upper Gears/Bearings were starved. Most VPs have a Hexagonal Bolt/Screw a the top of the Outdrive housing. It will also be a Dipstick. Remove it and see if there is any Oil on it

    V4 - Minimize Chances of Broken Rings

    Force 2 cylinder throttle cable adustments

    Hanging over the transom above a Flywheel spinning over 4500rpm, is not my idea of a good time, especially if the Water, isn't like Glass

    Force 2 cylinder throttle cable adustments

    Every Lake in my Province has Leeches, in almost 70 yrs, I have never had one stick to me. Of course I stay away from Weeds and Reeds when in the Water, as those Blood Suckers tend to hang around there waiting for a Fish. In 87, I went swimming in one Lake. got back in the Boat, and had a bunch...

    I would suggest you contact Comp Cams, they would be the Best Source. Due to changes in Valve Train Geometry, you may need to use Roller Rocker Arms, and possibly slightly different length Pushrods
