Drill and tap the drain plug?

[Marvin willis]

Has anyone drill and tapped their drain plug so they can use a drain plug light on the newer Yamahas? I think this is gonna b one of my winter projects.

Is the Yamaha not a 1/2" NPT? Most of the lights I've seen are. No tapping/drilling required, if so.

That looks like one of my interior plugs? but I don't have any experience with a 2018...

I sit corrected.

 

[Marvin willis]

Yep. The exact one

Not sure I'd drill and tap the existing fitting on the boat. I'd be more inclined to install a new one:

Ugh. Forgot about the new Yami hull design. (I'm livin' in the past!)

No, I doubt the one I linked to would work.

I have a plumber friend brainstorming for me. It will b tested to work before applying to the boat.

Anyone able to come up with anything?

I have had both, and the plastic one is easier to insert and remove and can't be lost. I'd trade you if I could. I have the bronze one now. Don't change it if you can help it.

I decided to buy a underwater light and leave the drain plug as is.

How'd you mount it? Really not wanting to drill a hole in my boat in fear of it leaking

Use shallow screws with 5200 in the mount holes and run wire up above the water line and in thru the hull.

Just drill a hole in the boat and use a proper light. Those drain plug lights scare the crap out of me, just something to get snagged on a log and rip a giant hole out the back of your boat.

Sealing underwater holes is so much simpler than you think once you get the courage to bust out the drill.

I haven’t installed it yet but it’s 8000 watts

If it's 8000 watts be sure and use at least a 667 amp fuse on that circuit. Just kidding, I think you meant 8000 lumens.
