shaft vs. saildrive

Have been hearing several concerns about boats with a saildrive sytem for power, that the saildrive is a a maintainance concern especially in the waters of New England. Electrolysis is a major concern

Why would the waters of New England be an issue? How are they any different than anywhere else?

No. Saltwater is saltwater. We are not talking about some force of nature on a regional scale. Corrosion issues are generally due to a problem aboard the specific boat in question and have nothing to do with where in the world the boat lives.

Saildrive legs can corrode, but properly maintained and protected by zincs, they are no more prone to this than shaft/prop arrangements.

Agree. THe proper use and maintained are the key. I believe SD is a viable alternative. As we gain more experience on SD, it will replace the shaft. I hope the engineers are working on one that can rotate from side to side (left and right). Bow truster will be replaced.

If the hull is properly designed and the SD is properly installed. A big hole at the bottom of the hull is my least concern.

Nahh - SD can't swim nearly fast enough!

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.
