Product Description

This drain plug is ideal for boat transoms, fish wells, bait tanks, water tanks, coolers, ice chests or almost any application where a positive sealing drain plug is required. This drain plug is not only quick and simple to install, but it also provides a definite cost advantage over outdated, leaking flared-type drain tubes. This retained plug will not get lost.

Perfect fit for 2017 SkeeterZX250
A stump broke the thumb/finger part that you grab to screw the plug in. Once I was finally able to get my broken one out the new one screwed right in. The coarse threads were a exact match. This product fit my original flange on my 2017 Skeeter ZX250.

This was almost and exact match to the original boat plug in my ‘02 procraft. It does seem to want to cross threat at times but I always make sure it seats correctly before tightening down, takes an extra 2 seconds. Really like the rubber O ring, makes a great seal. I also packed the edges with marine goop before tightening down, no leaks

Product showed up about 4 days late but amazon gave me a 5dollar gift card for the extra wait. I saw on other reviews that people received the fine thread plugs which I was hoping for since my boat had a fine thread already but I got the one in the picture which was fine just swapped it out and added some goop doesn’t come with any hardware but mine from my boat lined up no problems!
