Have you tried disconnecting the charging system completely to see if it will get on plane? I would do that, and disconnect the black/yellow kill wires from the switch boxes and see what happens.

explain how to safely disconnect charging system

[Smalltownbassin]

Disconnect the regs red wires and cap them off.

Voltage drop on a CARB motor should not kill it, especially not instantly. Its easy to tell the difference between an electrical engine kill and one sputtering out of gas cause the fuel pump doesn't have power. He should post a video of it or do some of the troubleshooting things we have said thus far.

Bad battery connections, cables, batteries etc. normally burn up the charging system, not necessarily kill the motor or the whole vessel power. Or if the vessel did loose power the engine should not, theoretically, die. Now I know theres weird things that happen, especially when regs get shorted and the stator is affected...sometimes the running side of the stator gets compromised even though it makes no sense.

it runs out of gas because pump loses power.

it runs out of gas because pump loses power.

So its a gradual sputtering die-off. Not instant like a kill switch? And it will lurch a few times and try to go before it dies?

[bullet123]

yes. falls off plane and bogs as you pump hotfoot. its not an engine problem. something is killing power source to the boat. if I was using a pulse pump im sure it would keep running.

[bullet123]

im pretty sure its the hot wire going to ignition switch

Running to many things on one circuit.

that's what I thought at first, so I put electric fuel pump on a relay with its own ground. I would have thought if I had to much load on the hot wire it would blow the fuse. the bad part is..... im doing so many changes at once, now I wont know what I did to fix it.

[racervboat]

I was just going to say that,get it fixed and you wont know which one fixed it.

[bullet123]

fixed is fixed I guess.

[racervboat]

Have you spread the terminals on the eng harness from the boat and plugged it in the motor harness and then clamped it with a worm clamp?

[bullet123]

Never thought of that. you mean spread the male pins? Ive done that on efis

[racervboat]

Yes seen it many times before,wont do it in the driveway but when you go bouncing on the water they short out.

[bullet123]

good idea. thanks

[racervboat]

Even did that on my old mans bayliner I/o was only a few yrs old mercruiser kept dying out on the water put a clamp on it never did it again.
