Here is a pic that Bryan wanted me to post...

Flame arrestors are custom fab :drink:

Also note that the boat was an absolute handful at 80 with props turning in.:helmet:
Turning them out was a night and day difference. He has permanently switched his controls to spin them in the much safer out direction.

Like he said, turn them out. Hammer down.
Pretty sure I can get in the 90’s with some 30’s props. Got a set of 33 for low elevation will have to give them a try from fun.
And yes the Arrestors and awesome. maybe he'll build you some :stooges:
