1989 Guardian w/1989 200 OMC VRO (Just aquired from the Feds). Sprays a rooster-tail and looks like the motor is too low. Before we send it to the "experts", any idea what mounting hole the engine should be mounted on? Would like to fix it without the paper work hassel.

Go all the way up and see how it does. Tad easier to lower than raise. One thing though is that must be one well built engine to last 14 years on a gov boat. I thought the had to repower every few years but I guess not.

The Vee shaped spray coming off an engine is a definite indicator of engine mounted too low. BW recommend for that hull that engine be raised one bolt hole (3/4"). But with that much power, you might want to consider 1-1/2". Consider an OMC "Raker" prop, or similar Mercury Laser II. For the best holding in rough water, at this transom height, try the 4-bladed Offshore that Louie Kokinis uses on his Guardian.
