HD,
I'm not a outboard tech,but just a thought high octane fuel is harder to fire than pump gas.
Have you heard about the rumble on the river?
It's in Carrolton Ky.,right on the ohio river.
Aug 2,3,4 this yr it will be dedicated to outboards,but anyone can participate. I think we'll be there with the hydros.
There gonna keep it no wake for us to race.
Sat evening the city of carrolton is going to parade us thru town behind the fire truck and police cars.
There will be boats from as far away as Canada and Florida.
Should be a good turn out.
