My previous 2330 had a similar problem with a Suzuki 250hp on a bracket. The scupper balls on the backside of the boat were not sealing and allowing water to flow back into the boat. I replaced those and that worked well. You can also check to see if there is any water inside your bracket (if your motor is mounted on one and not the transom). Lastly, moving the batteries forward into the cabin would also help immensely.
I have a 1993 2510 and had water always coming in. I have 2 Suzuki 150 on a bracket. I replaced the flappers with duckbills , link below, now a 99% improvement. I also added a windless and 100 feet of 5/16 chain up front, this raised the stern and helped balance the boat under way.
Thank you for the responses, I have checked for water in the bracket and there is none. I have the ball type scuppers but have ordered the th scuppers as recommended. I think I will move the batteries into the forward cabin which should take about 175lbs from the stern and add 175lbs into the bow area. Will the long cable run cause any problems with voltage or amperage reduction?
