Not sure if still available this year but, last year and years past, King Isle Marine in the SF Delta had High Test petrol with no ethanol... pricy though! Some of my "Fountain" and "Donzi" go-fast buddies always fueled up there.

I had a friend that drove a river boat in Nam. The stories he told were awesome. They would be running WOT and if they took on fire, reverse gear on one engine and it would spin the boat 180 and then back they went. He said they had skids of new engines and trannies on the dock. I think they used Crusader 454's in them and a jet drive. You couldn't full throttle a reverse in a regular drive.

I was lucky and stayed state side my time in the army.

The Uni's were tough boats to take that abuse.

I had a bit of experience in the PBR world but not in the Uniflite boat. The Uniflite, by the way, was powered with two Detroit 6V53s, not gas engines.

But in that kind of service one did not spend any time worrying about engine longevity or efficiency. It only had to run long enough to get back and nobody cared how much fuel it used in the process.

Better tell Twin Disc , all their landing craft trannys can not only run full throttle in reverse but one can SHIFT into reverse at full throttle.

Since WWII.

Okay, I won't run full throttle in my boat and jam it into reverse while maintaining full throttle. Nope, not a chance.
