Best Boat Marine Generator installed by skilled technicians at SB Marine Mechanic. servicing, Channel Islands, Ventura & Santa Barbara. Having a quiet, reliable, efficient generator should be at the top of the list of important components for Yachts and Sailboats with well-equipped galleys, air conditioning, heating and lighting for staterooms – or large sportfishing boats with multiple LiveWell’s, an array of electronics, downriggers and electric reels. SB Marine Mechanic has put together a list of what we think are some of the best boat marine generators on the market.
