I've got a 2001 optimax 200 hp. it has already had the catastrophic failure that they are known for and has been fixed. Now i'm seeing that the Tach likes to jump around. also, my new last year optima blue top battery that was fully charged before I put it in the boat was just plain dead the last time we went out. the alternator on the boat appears to be charging and I didn't leave any of the peripherals in the boat on to drain the battery out..... I've never had a problem with the battery running down before. I keep reading online that there are voltage regulators that can go bad and cause the tach to jump and cause all kinds of other problems, except I can't find one on my motor... my motor has an alternator and the alternator has a voltage regulator in it but my voltage gauge doesn't jump around when it's running (only the tach jumps). Any Ideas as to whats going on?
