The newer engines with knock sensors automatically put the computer into a limp home mode.... retarding the timing and drastically reducing the power output so as not to damage the engine.

I would not run anything lower than 89 in a boat. A boat motor is CONSTANTLY under load, even when idling.

If you do the math seriously how much money are you going to save per fillup? $5? $10? Is it really worth risking your engine for?
