I have a 97 seadoo gtx and noticed a leak on the tuned pipe, in the common area for holes to form. I have repaired that and am getting ready to put it back on. I got a new gasket for where the tuned pipe and the exhaust manifold come together. Should i apply some red rtv around by the screws to make sure i have a really good seal or should i just use the gasket. I also am wondering about where the tuned pipe hooks up to the pipe cone with the clamp. I didnt want to pay $90+ for the recommended loctite 17614 so i got some red rtv to hold them together. Where and how much should i put in by the brass washer?
