I have run 87 in my ScarabIII with no prob but normaly run 89. My Mags are all original with about 400 hours on them. To be honest i cant tell any difference between the two dif. octanes in my boat.

The engine is designed to run on 87 octane. If you use higher octane it doesn't burn as fast and as completely and you are actually loosing power. Bump the timing up to 34-35* and then run 89.
