Yamaha Mechanical Access Port Riser

Sale
Regular price $109.99

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.

Fit great but...

The screws provided are allen head and the nuts are Teflon lock nuts. Both are soft stainless steel.
About half of my allen head screws stripped the allen out before getting the nuts tight.
A good Phillips head screw would have worked better. I almost went to hardware store and got Phillips but being lazy I went with what you sent. Half way thru all the tools got thrown and some bad words said. I would have saved time and headache getting Phillips before start.
Other then that it's great.

Well made but mine needed customization

Great fit but due to my boat the 3 rear center bolts either need to be longer or I trimmed the fiberglass back a 1/2” to be able to access and tighten the nuts. Looks like it will seal well now. Silicone around access hatch and the edge of the clean out port hatch. I also added 2 more screws to the rear center clean out port hatch as I noticed the hatch separating from the transom creating another leak point ast the silicone weakens.Great product and highly recommend.

Very easy install and keeps water out!

Very easy install. I wanted to install before going in salt water because of Yamaha Jetboats tendency to splash over the back and enter the bilge. This appears to have done the trick. I didn't see any water on top of the pumps and other things in the bilge area

What a difference! After a weekend on the lake, the boat was dry. Normally we would have had significant water intrusion after a day on the water. We decided to rent a slip and every day I would check the engine bay, dry. Then we pulled the drain plug on the ramp as we left and again, nothing. Nothing happening when pulling the drain plug is the best feeling after a weekend of boating!

Works as it should

Works as it should. Solved the problem of water supply intrusion.
