I'd check the oil pressure switch, generally the boat will run while you have the starter engaged, and stops when you release the key, the switch cuts power to the fuel pump...

I'd bypass pass it to eliminate it, probably explains why the issue was intermittent. You should get the manual and verify the wiring...Last edited by parrothd; 03-18-2013 at 03:22 PM.

This sounds promising. It didn't know what to look for while I was at the lake this weekend. Makes sense.....I forgot to mention that I don't get the 12 volts to the fuel pump when the key is in the ON position.
I'm a couple of hours away but wish i could go right now and try this.
Fogot to say a BIG...........
THANK YOU!Last edited by Bend; 03-18-2013 at 03:57 PM.

Wiring diagram for LSV/Kamerbra probably the same for all early models.

parrothd,
Finally got back to the lake.
replaced the oil sensing unit. Still no luck. Everything remains the same. I get fire from the engine in start mode but engine dies when in "on" mode on ignition.
Checked wiring as best as I could.
Could I have replaced with the wrong ignition switch? (The fuel pump does not cycle in the "on" position but has power in the "start" position.

If this helps you, my fuel pump cycles on when I move the keyed ignition from OFF to ON.
Perhaps it would be helpful if you posted a picture of the wiring on the back of the motor that you stated was spliced. The wires that you stated were spliced, where do they go? Can you tell why they were spliced?
You may want to get the dealer to print off a wiring diagram of your boat.1997 MasterCraft 205

boat cranks but wont startr
If the pump doesn't prime when you turn the key from off to on (not all the way over to hit the starter) then your problem is in the wiring. It should prime for a couple seconds then stop until you start it, then it stays on. This would explain why it shuts off when start is released, 12v to the fuel pump is being cut too. Somewhere down the line power to the fuel pump and likely the ignition are wired incorrectly.

Should be somewhat straightforward to trace down with a multimeter and wiring diagram.
