My top end speed was off about 3 MPH and I am not sure yet if this was a factor or not.
Funny story here. 8 o'clock Sunday morning we are putting the boat on the trailer for the trip home. Truck is spinning his wheels at the ramp so I put the drives in gear to help push the truck up the ramp. As we came up the ramp I,m still on the throttles and the tips came out of the water. Sounded like a bomb went off till I got her shut down.
After I had been so good all weekend trying not to piss anyone off. Gilford,NH got up early that morning! LOL

I know some people are using an elbo on their tail pipes that put the exhaust underwater at idle and above water on plane. We contacted Gibson but they only make them for 4" and 4.5" tailpipes. Who makes them for 5"? Anyone using them? Do they work well?
Screw em buy them a for sale sign and tell em thier movin.

There is no reversion. The tips need to be 4-6" underwater to work. There should be no reason to drill relief holes. Nobody makes 5" except CMI. Ateco a CMI distributor took care of me. In Wisconsin the DB limit is 86. We were just at a Poker Run in Oshkosh and the Sheriff did not even look at us we were so quiet. No way you can lose speed as there is zero restriction.
