[Jomatra]

We purchased 2000 3500 open with 370 Cummins last fall. our first outing was to bring the vessel home. (410 Statute miles). I have 2 questions. We installed 5 new batteries before our trip. Both banks of batteries would only charge to 12.5V while under power. When at the dock with the charger on they would charge to 13.5V. My past experience has been that the 13.5V is more the normal. Any thoughts?

My second question is - the tachometers get erratic after about 20 minutes at cruise speed. The starboard engine doesn't record the actual Hours of run. This has apparently has been a problem for some time as this engine has nearly 80 hours less than the port. At the survey when the question was asked why, the owner (second) said that it had been that way since he purchased it (2 years). Has anyone experienced anything like this ?

Thanks John
