Now the problem (I think I know one solution but seeing if there is something else I can do) the gps is hooked up to the house battery. I have a starting battery on its own. GPS is on and when I start the boat everything is fine no blink out. However when running I went to use the mercruiser power trim and NYC black out on the GPS(trim is on house battery). Had to hard start GPS.

Problem solved

The long answer to an easy fix.

After running a temp. wire from battery to power trim on starting battery everything worked fine. Then at the Seacraft outing while at idle speed I turned on the blower for the motor and the gps blinked out...hard start

On Sunday on the way home the gps crapped out and would not come up to load. It would show the logo and then die. I really need this.

Monday call Garmin and they tell me go check my house battery...sure enough it was on its last legs, enough to run stuff but not taking a real charge. so just under 8v and the Garmin would not fire up. Tried gps on starting battery turned on trim and blower and it just smiled pretty and stayed running.
