Looking for new tips but looks like all the ones I see are screw in and my trumpets have bolts that go thru the transom and nots on the back side.  Looked on cp performance and looks like all they have is screw on. Like some slant tips any othe r places to look?

Thanks guys/gals

You use long bolts. But the bolts aren't part of the exhaust tips themselves. Use stainless bolts only with nylock nuts and nice thick washers on the inside. 3m marine silicone to seal them. The bolts will probably be in different spots so be prepared to fill some holes up with epoxy filler.
