OK, this is really starting to p*ss me off.
Took the boat out last night. It coughed a little when first started but as it warmed up it smoothed out pretty well. Later it died again on acceleration from neutral idle. Runs pretty good at idle and very good at speed. It only died once but that was almost enough. Both batteries were almost dead after cranking only a couple of times. I knew that one had a bad cell but I thought the other one was ok.
My question- when running my ammeter shows just above 12A on one battery and just under on the 2nd. Does this mean that the batteries aren't charging or that the motor isn't charging the batteries? Since the boat is new to me I wasn't sure of age but found label on Battery. They are 3 years old.
I figure that the best solution is to replace them both. One with a starting battery and the other with a combo deep discharge/starting.
If I get good cranking batteries, I can live with the occassional stall until i either figure it out or give up and take it to a mechanic.
PS. As far as speed is concerned, the 175 Merc pushes this boat, a Wellcraft V20, faster than anyone really needs to go.
