- Cost: $80.64
The existing Vetus model TRC75 3-inch steel transom exhaust connection was removed and it's hull hole closed out. A 3-inch Centek Thru Hull Exhaust Fitting ($58.49) was ordered and received. This fitting has a weighted rubber flap that helps to prevent the backflow of water.
The new Vetus NLPG Gooseneck Muffler was connected to the 3-inch engine exhaust hose to test fit the installation and determine where the new exhaust fitting hole would need to be drilled. A 3 1/8-inch hole and four mount bolt holes was drilled in the aft port side hull.
The new Centek exhaust fitting was installed and sealed in place with a tube of 3M 4200 Marine Adhesive ($22.15).
After the sealant had cured, the excess sealant was trimmed off with a razor blade.
