Hello.I bought new exhaust thru hulls (corsa),nice stainless. Anyway, they seem like they restrict the water exiting. My engine arrangement has no risers, only elbows. So, I thought, any more protection from backing into a sea etc. would be good. I guess I'm just wondering if anyone uses them, and/or if they are a help or a hinderance. If they are going to be a problem, I could maybe drill out the baffles. Thanks for all the help on my project.
Engines are twin Crusader 454 FWC

Be careful! Water coming in from a sudden stop could wreck those engines, which are famous for sucking water in through the exhaust ports. I'd do all I could to prevent that, including adding check valve mufflers.

If they're the ones I'm thinking of-stainless with an internal weighted flapper valve-I wouldn't trust them near the waterline. I think they are more for cigarette style boats. I would go with a standard exhaust tip with a rubber flapper. As Jeff pointed out, due to valve overlap those engines are like vacuum cleaners and a fast stop will ruin your whole day. Stu |

These are the welded in type, not the moving ones. Thanks |
