Transom Cover Plates

Transom cover plates are for use when the exhaust ports (tips) are removed to install over the transom style exhaust. The plates cover the holes left in the transom. These plates are machined from 6061-T6 billet aluminum - they are not inexpensive castings. The outside plates are 5-1/2" in diameter to cover the largest exhaust ports. The inner plates are 4-1/2" in diameter. The outside plate is threaded on the back side. To install, you merely sandwich the transom of the boat between the plates. No fiberglass work, no hassle. If you ever decide to change your exhaust back, just remove the plates and your ready!

Sold as a kit to cover 2 exhaust holes. Due to varying transom thicknesses the covers do NOT come with mounting bolt. Requires 5/16" bolt long enough to go through transom and internal mounting plate.
