I have a 204 FS with a 4.3 MPI Alpha engine. I would love some advice on adding engine space insulation and quieting the boat which is noisy at cruise speed so that conversation is challenged and very noisy at high speed, particularly for back seat passengers. A bit less so without the bimini up.
Is a through the hull muffler modification a possibility and or just adding sound proofing?
Love this boat otherwise
I'd appreciate any advice.
Thanks
