Sorry to hear its costing so much and you haven't resolved the issue yet. As far as the 12v outlet not working, I would check for a blown fuse.
Thanks Mate, as I said originally there is 12v power at the socket when tested on the meter. But there must be some sort of feedback /ground issue as no electronics will work when plugged in. ie both the inflatable air pump and the mobile phone charger will work in the car, other boats, but not in off the lighter socket / outlet. Sound system works when connected to a jump start battery but not when connected to the boat battery, but there is 12v power to the radio & amp.
I see the mechanic has moved the earth cable from the back of the motor to the battery. His reason is that the original position was difficult to get to and was corroded so it made sense to move it. Not sure if moving it from the engine block to the battery would cause these issues?
Can you post up a pic, the ground cable should go from the battery to the engine bell housing.
