First of all, my new 2+2 is awesome! 250R, 1/2" above pad, manual Allison jack plate, 30" Promax. Hole shot is great, but the damn venting at break-over is really annoying. I ordered the exhaust sealing ring for the Promax prop, but have read mixed reviews about the performance and how it kills the hole shot for some people. Does anyone have any experiences or advice to share?
