I have a 2000 Moomba MobV. I put it in the water today for it's first run of the season. The boat started up fine at the dock and ran good for 10 minutes or so. That was taking it through it's paces up to 35 or so and back down. My roommate was driving at the time. I then got in the boat and idled out. The boat then choked out and died. It started the boat a few times and it just immediately shut off. Now th eboat starts up fine but immediately dies.

This happened to me last year and the mechanic said it was a bad oil pressure switch(not sender). The fuel pump is cconnected through this switch so when the boat is turned off or the engine loses oil pressure it cuts power to the fuel pump. I know the sender is right above the oil filter, but does anybody know where the switch is?

The oil pressure was fine up when I was running so that leads me to belive it is a faulty switch.

Well I went out and think I found the Switch. It is a 3 terminal pressure switch that comes out of the top of the transmission end of the block. I played with some of the terminals and it started and ran fine as well as the pressure stayed at 40# or so at idle. I sell the switches so I may just replace it to be safe.
