Ok I had a fuel pump replaced on my 200 merc at the shop. When I got this boat and motor there are four wires that go to the motor and the one pair where not hooked up and I drove it that way forever. Now at the shop they hooked up this wires and I took it out had no problems. The next day I kept loosing prime. I unplugged the two wires like they where before and runs fine. Now whats up with that? what do this four electrical wires do. I would look in the manual if I had one..... <br /><br />Thanks,
