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?

Really? Why do that? Why not just retard the timing a few degrees automatically until the knock stops? Interesting, looks like I will have to do some research.
I run 91 regardless because I need all the HP I can get in my old sled!
