I am looking for a wiring diagram for a 20 ft sutphen with a 350 chevy engine.

I bought a boat with out engine and acceseries.
anybidy know where I can find one on the web??

I am especially wondering about the three wires coming off the prestolite distributor and coil. There is a purple and two black wires. Purple is a spade and one black is a spade, the other black is a small round. any I dea what is supposed to be hooked up here???

The boat has a lucas engine speed limiter wired in, I am wondering if I am missing a part for this unit??

anybody got anything on this??????

you should be able to find a standard wiring diagram for you motor in the Mercruiser service manual.
