Yes, I would lock out the vacuum pot...It can be removed and locked with a simple piece of aluminum, marine engines are under too large of load for the vacuum advance to work...

If you have an enclosed engine compartment, I would discourage it totally....

Not likely safe and /or "Marine approved" and as Glenn said the Vac advance is of no real use ,However in a Jet boat application , if you do decide to use it/one you'll have to modify it to give a greater total centrifical advance or run quite lot of initial to get mid 30 "ish" total Tom
