Has anybody ever asked Yamaha and gotten an answer from them? I need to replace my starting/cranking battery and I've heard people on the board say that "most outboard companies recommend no less than 1000 MCA's for your starting battery". But when I looked it up in the owners manual it says a minimum of 675 MCA's. A starting battery with 1000 MCA's is hard to find. Some of the more expensive batteries (Optima's, DieHard Platinum series, etc.) have 1000 MCA's, but I can't see paying $230+ for a battery. The biggest cranking battery at Wal-Mart in the EverStart line is only 875 MCA's....
