2025 Best Modification Award (if not the best all time mod) goes to TeenGee

[FSH 210 Sport]

I meant to post this before the new year.

I’ve been on this site for five years, just a Padawan but still learning, I’ve seen some really great modifications with instructions for the average do it yourself make my boat better person. And what I’m proposing does not take away anything from how great I think those idea’s are, @drewkaree ‘s anchor locker drain modification comes to mind right away. The quest for the dry bilge is something most strive for.

@TeeNGee ‘s contribution of figuring out how to add an O ring of the proper size to the late model clean out plugs to tighten up the fit and eliminate any water coming in from there has to be one of the simplest and greatest idea’s on our jet boats. He even went so far as to post up a PDF of all the various O rings of the correct diameter and different cross sections to adjust the fit if the one he posted was too tight.

The added O rings effectively eliminates any water getting into the bilge from the clean out plugs because there is either no water getting into the tubes or so little that it is inconsequential. So many people have posted in the past how their hulls take minutes to drain bilge water after pulling the drain after a day on the water. Secondly it seals off any air that could get pulled past poorly sealing clean out seals that could contribute to cavitation. Combine the @drewkaree anchor locker drain fix with the @TeeNGee clean out plug O ring mod and most boats will have a dry bilge. An elegant solution to say the least, no more slathering on toilet bowl gasket wax that works temporarily but leaves a long lasting mess.

Just brilliant!

Well done!

Thread 'Another Clean-Out Plug Thread'

Nov 20, 2023

There has been lots of discussion about water on top of the clean-out plugs and that its fairly normal. Many people believe that water gets into the inspection port area from the swim platform when stopping, etc. and it fills the clean-out access tube.

I used to subscribe to that theory as well.... until I purchased the 275SD. The inspection access covers and clean-out ports sit pretty high up off the swim-platform. You would need to stop dead from 50mph or have a 3 foot wave come over the back of the boat to get water on top of the clean-out plugs. When I first started using the boat I...

Boat Stuff Thread 'O-Rings for Clean-Out Plug'

Jul 7, 2025

O-rings to help seal the clean-out plug(s) and prevent water from sliding past the plug. On my boat, I found that my plug was always full of water and may have been overflowing into the inspection tray. Thanks to @TeeNGee, who found that this O-ring could help better seal the plug and prevent water intrusion (Thread). Since installing this O-ring, my plugs are bone dry.

These aren’t super easy to find/buy so I bought them in bulk. I now have a BUNCH to move

$5 each, shipped to CONUS via USPS. You’ll need 1 per plug
