I've posted regarding our problem in another string, but would like to know if anyone has any suggestions or has experienced a similar problem.

We traded an Islandia for a Challenger X last September and have taken it back to the dealer FOUR times now due to the same problem - after a couple of hours out on the water, the boat dies. They have checked out the wiring harness, changed fuel pumps, etc... On the last trip to the dealer this last weekend, they had a Mercury representative present who stated that it was a wiring problem, then a fuel pump problem. They had a fuel pump replaced and we took it out. Again, it ran fine for a couple of hours then died again.

When the boat dies, it sputters for about thirty seconds then completely dies. The starter will work, but the engine is not getting fuel. Obviously, something is causing the fuel pump(s) to malfunction, but what??

We are at the point of telling the dealer to come get the ?*&% boat!

Thanks,

Jami

i am not a mechanic by any stretch of the imagination - but what about the feul filter - or fuel seperator - is the fuel contaminated?

While at the dealer last weekend, they researched that issue and bypassed our gas tank. Didn't seem to be the problem.

Don't know if you're still having the same problem. I had a problem of not getting any fuel to the engine on my old U185 with the Optimax, and it turned out that the fuel pump wasn't able to pump the fuel from the tank to the engine, if the fuel line is dried. Check your fuel line from the tank to the engine to see if there's any fuel in it. If not, you may want to take a look at the anti-siphon valve at the fuel tank. There's a little stainless steel ball with spring on top of the tank, it may be bad - resulting in fuel draining back into the tank, preventing fuel from being pumped to the engine. The fuel pump is not powerful enough to pump fuel from the tank to the egine w/o being primed.
