Someone I know and respect who has a great deal of experience with sail drives recommends not using the water intake that is part of the sail drive. Rather, seal the intake with epoxy and fill the leg with antifreeze mix. Then get your cooling water through a conventional through hull. Not having sea water on the inside of the leg will dramatically reduce the possibility of corrosion - and yes, you still need to keep a close eye on your zincs.
Back home on Lake Ontario after something over 36,000 nm circumnavigator. Not surprisingly there is a lot of stuff I want to get done on Ainia both cosmetically and functionally. Getting an early start so it will be ready to go for next summer (Lake Superior?).
