Yamaha Mechanical Access Port Riser

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
