Motor well scupper.

Post by Ixneigh » Tue Aug 06, 2019 4:28 pm

Tired of that motor well drain plugging up, need to do something about the plumbing, the sink line and the scupper line all going to one outlet. And poorly.
Option 1 install new through hull just for outboard well. Replace drain with a standard through hull and use good hose to connect with double clamps.

Option 2 use larger throughhull, and continue to tee both sink and scupper drain to it. Locating a proper seaworthy T junction might be an issue. None at west marine. Only plastic type. Upgrade plumbing as needed.

I looked at option 3, cutting a drain right through the transom, but didn’t like that as it was too close to the motor mounts.

What is exactely your problem/concern with the factory stile?

As long as you don't come 3 inch higher obove water line it does not look as an improvement.

What do you want to be better after the mod?

Stock drain is too small. A dead June bug will clog it. Anxious to see what he does on this. :)

i had the same problem, even very small debris would block the factory setup.
and if you tried to back flush it with a hose, it would take the path of least resistance- and blow back into the sink

i put a thru hull in the well, and put a new thru hull next to the sink one on the transom, dedicated solely to the motor well. decent 3/4" hose and double ss clamps both ends.
i also then upgraded the sink drain with the same, smooth 3/4" hose, got rid of the corrugated one that trapped residue like a gold sluice box.
never had to touch it since
