1998 Mercury XRI 150 HP Motor Alternator Questions

[jrnyldo]

I have a Series 27 and a Series 29 battery. I currently have the Series 27 hooked to my pumps, lights, Starter for the Motor, and 2 HB units, 1198 and 898. I have a second battery, Series 29, Hooked to a Blue Seas fuse panel that powers a HB 999, HB 360 ASTM, and Humminbird 5 port Hub. I would like to install one of the Battery Switches that allows me to switch between battery 1, Battery 2 or both or none. Does the Alternator have enough power to charge both batteries if I have the switch in the Both Position?

Regards,

Bob Payne

As long as the batteries are not completely drained, there shouldn't be a problem. The more discharged the batteries are, the heavier the load on the alternator. That motor probably has a 35A alternator, so if loaded heavy it would be working harder. That equates to heat.

Any other input?

Any other opinions or am I going to have to reach out to an Outboard Mechanic to get info?

I figure that is totally dependent on the driver and how long the motor is ran.
A short run won't do much charging..
