I have a 1991 270 Sundancer with twim 4.5L engines. I have 3 batteries, 2 are on the port side and 1 on the starboard side. The starboard engine turned over very slow when trying to start. If I use the emergency start switch it turns over with no problem. Thinking it was a battery, i replaced the battery on teh starboard side, but this did not cure the problem. Is it possible that 1 of the 2 batteries on the Port side start the starboard engine?
Does this mean that the starboard battery is only to power accessories?
