I'm running zoomies on a BBC in my Tahiti.. I feel I have plenty of room but the headers get super hot and heat the sides of the boat up .. any words of wisdom that can steer me in the right direction to reduce temps and make the boat a lil safer

I’d ditch the zoomies before you’re asked to leave or be fined for loud exhaust at a lake or on the river, besides you will produce more power (low end torque) with a nice pair of quality equal length long tube headers. Plumb in a regulated amount of water into the primary tubes to keep the heat down, it will be slightly quieter, (no hassles from rangers) and definitely safer and more comfortable for passengers in the back. As a side note, your engine’s air/fuel mixture’s for the front & rear cylinders will be much better off getting away from a single carb on a tunnel ram, I’d choose a nice single plenum manifold or if your set on a tunnel ram go with dual four barrels, if your concerned about fuel mileage go with two vacuum secondary Holley’s, just my 2 cents worth.

Thank you for the info... I pretty much assumed all those things lol... we don't really get hassled for noise were I'm from(not sayin it won't happen) I have wet bassetts and have ran em for years.. I just see a lot of ppl run dry exhaust and now can't really figure out how due to my temp issues.. I'll go back to the over transom if I have to but always wanted to run zoomies so I took a chance

Can't tell the coating but you could try ceramic coating and/or wraps like DEI titanium wrap. Might help some
