As I posted earlier I am looking at a 222 Shabah that has a 7.4 mpi. I think it's a waste having that big motor and not being able to let it talk. Has anyone installed a captains call exhaust system on their Mariah? I have looked at the kits from Corsa that come out the side and I was wondering how that would work since the sides are kind of layered and not smooth.

Thanks!

This topic has been somewhat beat to death on here. To do it properly with OEM style parts will cost around $1500+. Most people have seen extremely minimal gains from adding thru-hull exhaust, at max 1-2mph.

I personally, think saving the money and using it for fuel and/or frosty beverages (to enjoy at anchor/dock) would be a much better investment. If you want thru-hulls, look for a boat with them already installed instead of adding them. But, if you're insistent upon adding them, feel free to search the board for "exhaust" and you'll find a lot of posts about it.
