I recently purchased a used boat with a 135 Optimax (2005) Saltwater. It ran fine the first few times out. This past weekend I put it in saltwater and ran about 40 miles with it. I put it on the trailer and didn't notice anything. When I got home I could hear something running. I took off the cowling and the fuel pump and oil pump were running. I disconnected the electrical harness going to each and when I did this, they cut off. When I reconnected them, they cut back on (the ignition was off). I put on the rabbit ears and cranked up the motor, letting it run for 5 minutes. When I cut the motor off, the fuel pump and oil pump also cut off. They haven't cut back on yet to my knowledge. Does anybody know why this might have happened?

Master power relay. There are a bunch of fuses in the motor. Most have a red/white lead that comes out of the relay. Check for juice there when the problem happens. |
