Dave, that is awesome. Don't you just love the Pro Bros! Thanks Akahoverit for helping out Dave with his setup. Now all you need is practice practice practice and about 10 gallons of ProBro fuel.

Might have to try that 15-4 prop setup..Been using the 16-4 but maybe that's too much? So who's got the specs on doing the mousse can muffler for the 90 engines?
