Would appreciate some debug help. Bought this boat in 08 w/50 hrs on it. Great boat, never an issue...now 205 hrs. Was out on it yesterday pulling kids wakeboarding and tubing. Headed back in for the evening pulling a tube at 25mph and the engine quit. Never sputtered never ran bad just died. Made me think electrical, kill switch etc.

Checked kill switch thoroughly, all battery connections, fuse panel under instrument panel, inspected wiring in engine compartment, hit the fuel release valve (schraeder valve sp??) which sprayed fuel out...do not have a gauge yet to measure psi though. Nothing obvious.

Not sure what to do. Keep boat on a lift on the lake and no trailer. Would like to troubleshoot before trying to take it somewhere. Any help out there? Thx!

Fuel pump

Yep, I'd check the fuel pump. Do you run it on less than 1/4 tank sometimes?

Yes. I do run it to or below 1/4 tank. Would I still have pressure in the fuel line if the pump failed? And would just go from great to dead with no sputtering?

Thx..

Just change it if you haven't it'll fix it I'd bet money on it there are a bunch of threads on here about how to do it yourself for a 6th of the price of the mc dealer

From what I've read, there have been others that have experienced similar failure as yours, so yes, I think it can go from great to dead in a flash.

Ok. Thanks for the replies. I will definitely give it a go myself. Appreciate the help.

I just experienced the same thing. In my case, the fuel pump relay was bad. Either way, if the fuel pump stops working, the boat can stop suddenly without any sputtering.

I'd check for spark first. Crank it over with the coil wire removed from the cap and hold it close to the engine for ground.

If ok, then pressure test your fuel pump. The plug connection at the top of the fuel pump module can sometimes be a problem (bad connection) so give it a good look.

Running less than 1/4 tank is asking for trouble. Also your fuel filter should be replaced every 2 years. (or sooner with heavy use like in florida, etc.)

Did it restart or did you have to get towed?

I had to get towed. Luckily I had a neighbor that was down this weekend too and he came out and towed me in...towed in by a Malibu to add insult to injury.

My buddy has an 04 x star with same engine and same symptoms. Just stopped for no reason. We replaced fuel pump 25 hrs ago but don't hear it turn on with key. Also get no spark with timing light when turning engine over. Led me to believe bad kill switch so we wired it together but no change. Checked the breaker near the ECM but didn't appear tripped unless it's just extremely corroded. Any ideas?

check fuses relays.. and connections. chase down all connections and make sure they are clean and battery has good output.

I to have had the same problem. 04 X2 with an mcx. I have gone through 3 ignition modules and still have not found the problem.

My 07 Star did the same thing. It was the fuel pump. I bought a fuel gage for about $10. Turned the key and no pressure at the shredder valve. I read the thread on fuel pumps... Bought two. Fixed it in less than an hour. I am no mechanic either. I would say to make sure you use a nut driver to tighten the fuel hose back on to the pump. A screw driver just won't get the job done.
As far a running you boat with less than 1/4 tank... Don't feel bad with this being such a common problem, I was kinda po'd that my dealer never mentioned that I really only have 3/4 a tank to use.
The good news is that it's easy to fix... I thought I could get my MC mechanic to do if for me and just pay him to do it (I'm no mechanic). He probably did the right thing and told me he couldn't do that for me.
If you can turn a screw driver you can change a fuel pump.

Any updates? I replaced all of my borg warner parts in the ignition with AC Delco and everything seems to be status quo. Heading out to the lake in the morning to make sure everything is good. Hope you got it figured out.
