Hey guys,
I have a 2000 Ski Sanger with the 330hp Mercruiser Black scorpion that is not wanting to run when it gets warm.

Heres some background info:
Worked awesome all last season! Used about twice a week all year! Then we winterized it, did an oil change, and changed the fuel/water separator. We filled it up with gas and put stabile in it, but did not run it after putting the stabile! (I know, my bad...)

So i get out to the lake last weekend and it was hard to start, but it finally did. I pulled away from the dock and was able to get it to plane out for a few minutes, but not to fast, just getting it warmed up. When it warmed up it wouldnt even go past idle.. It would sputter and backfire through the intake and then just die...

I dont get whats going on! It worked the last day last season and then start it up this season and it doesnt want to run!:confused: Please help me! I need my boat back, ha :(

Thanks guys!

-Jon

Did you get a hot horn or transmission hot light? It kinda sounds like its in Guardian mode...

Don't think any of that happened. Where would I see those lights?

I think it's either a fuel or spark probelm, but I'm really not sure

You might get more help on the Mercruiser forum. This is the black outboard forum.

It will run fine, but when it warms up it will barely go past idle

I got the problem all figured out! Bad fuel pump..

The ethanol in todays gas is destroying boat fuel systems. Having it sit in the fuel pump all winter corroded it and finished it off.

I have a new pump on its way and we'll be back up and running soon!

Thanks guys!! :)
