Yamaha Mechanical Access Port Riser

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!
