    I have 3 1/2 angle cut... just make sure you always run water through them. They burn out quick. I made it a habit to spray some water based dressing in on them when on trailer. Seems to make them last a bit longer.

    The outside looks bigger than 3... does it reduce in size on the inside? If it was to except flappers, there will be two small holes(top and bottom of each other). I have seen them on both ends of exhaust. Mine are on the inside end. If you dont have the holes for them, you need to drill them. The flapper comes with two small press fit bushings and you need to have a vise(if doing out of the boat) or a big C clamp to do inside the boat. I drilled out the bushing a tad to make em slide on easier.

    Ok I don't think mine is set up for them I don't see any holes. Ill order a pair, and drill in some holes I'm pretty sure there 3 inch ill double check. And yes they are same size all the way back even hose is same all theway to the riser and it fits snug over my riser.

    With your type of exhaust, you might not need them. Water has to travel a bit high to get over your riser. I have regular snails and both my flappers only have one side left and ran it that way all last season without water issue. I park my boat with current or nose out when I can.

    He hydro locked his motor. Couple of members suggested he might need flappers. Either that or he over pressured the block and pushed out a gasket.

    You could cut the angle off and put the clampon external Salisbury rubber flaps on that will last for years. Rex carries them.

    I doubt water traveled up and over his risers. I have snails and they are much lower to water level with only half my butterfly left. No water issues yet...I think his issue was poor gasket coverage at the riser or manifold intake gasket.

    I bet you are right. Either that or he pushed a gasket out by over pressuring the block.
