RPM and Pro pitch have a inverse effect on each other. Increase pitch lower RPM and vice versa
Your getting WOT RPM so you are where you should be with current amount of power your motor is outputting. If the motor is 100% healthy and is producing all the power it can then your done. Adding...
Agree with Gsent, your Bats are the initial issue. A AGM at 12.4V is 75% and going down to 11V is about dead
While the boat gauge may have an issue, the Alt should output 14 to 14.5V at the Bat, same as the Bat charger
Howdy
The max WOT RPM is 5200 so it was pretty close to it. Do agree boat should do better then that so wonder if there is something sly going on. Going from 4900 to 5200 is only a couple more MPH. Boat test should be at least 50
If boat was doing 39MPH and turning 3900RPM then motor is the...
Need to test a find out what the voltage level is at the drives. This is measured using a digital voltmeter and a Merc test probe. There are other manufactures of the probes but would need to look. The probe is basically a platinum coated wire wrapped around a short plastic stick with a led...
Don't know for sure which question is being asked, so I'll try all sides
Does the forward bilge have a bilge pump?
If it does then maybe that pump is there to pump the condensate out
If there is no bilge then the line was cut, unless there is a drain leading to amidships bilge
If the forward...
