I was planning to use pipe cast into the keel to cool the engine.!
{A Sabb 22hp}. The Keel cooler that came with the engine is 10' long
5/8 tubing My keel will be a long rectangle. Aprox. 10' x 15"x 15"
.. Glenn do you plan to use some type of flux on the tubing , Before
casting the lead ? And what type of wire do plan to use , To hold the
tubing in place Thanks CW
