^^^ And tons of low end torque.
That can also be a symptom of no water or not enough coolingSo far.... I've never damaged a gas motor in my boats, but have read up on some threads that do show some carnage pictures...
Where does most of the damage happen on the Zenoah and Quickdraw engines?
Big end of rod, small end ?
I saw a few that had scoring on the piston/ sleeve near the exhaust port. Is this type of damage due to lubrication issues?
High exhaust temperature vaporizing the oil ?
Or just too low of oil content?
Stu Barr mentioned that he runs 110 octane (or 100LL) w/Quicksilver oil (@10%), thru his CMB 27.0cc Alpha-EVO for best results
this is from his response (quote):100 LL is only 95 to 96 octane RM/2
