Slip,

I don’t think I ever put it on my websites, but have
almost certainly emailed it to someone in this group in
the past. Also, it’s slated to appear in SAIL’s March
2014 issue as a Cruising Tip.

What I made with PVC has served me well and I’d do it
again with no changes, but it’s probably not
ABYC-kosher and boat insurance companies might take
issue with it. If you feel compelled to please them,
you can make the same thing out of bronze for a few
hundred dollars’ worth of pieces. Whatever you do, DO
NOT USE BRASS. It will fail within a year or two. Note
that I have a separate, dedicated thru-hull for the
engine raw water intake. It does not pull from the
manifold.

PS: Please do NOT post the attached illustrations
online. SAIL magazine has first rights to publish them.
Thanks.

Have fun,

Tor
