Yamaha Mechanical Access Port Riser

Add vertical height to the location of your clean out port compartment's mechanical access port.  Adding this custom "STARBOARD" CNC fabricated riser will raise your boat's mechanical access port 3/4" above the deck.  Raising the access port up off the deck has the effect of keeping the bilge free from water intrusion that could be leaking from around the gasket or edge of the access port's frame. Fits: All Yamaha Jet Boats From 2010-Current (verify that your boat's access port dimensions are 8.5" X  15 3/8" before ordering)   Installs using minimum tools and hardware. Allow 30 minutes for complete installation plus silicone cure time. See install guide for installation instructions.
