06 XSTAR w/MCX 350 died while driving
 
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?

BrushyCreekXS 07-21-2013 06:47 PM

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.)
