Stepside,
Right.
I spent my teenage winters on my friends fathers' boat. New ribs, flying bridge, deck, new engine, closed cooling system, were just a few of the many mods over the years...in addition to sanding the hull and bottom painting every spring.
After installing a new deck one winter, the next winter we removed it all to put in a new engine; the following year out came the deck again and we plumbed in a closed cooling system...ethylene glycol...through hull running 20 feet of 3/4 copper tubing along each side of the keel. The engine never got above 180 degrees..
Payoff?
After college whenever I stopped by my friend's house his father gave me free lobster!
