2013 V226 Surging

Recommended Posts

lakerat    70

I took the boat out today (V226/Indmar) and it started up and idled but when I tried to move at more than idle speed it would surge back and forth.  It finally just died on the way back to the dock.  I changed the fuel filter but that didn't help.  It seems like a fuel problem.  Anyone have any ideas?  It's 2 hrs to an Indmar service center and they can't get me in until late next week.  I'm 70, so I don't want to miss any chance to surf while I still can.  Thanks!

Sounds like it could be a fuel pump or maybe even bad/water in gas......did this problem happen out of the blue?

I haven't refueled since the last time I was out when it ran perfectly, so I don't think it's bad fuel.  The only thing I've done in between is change oil and filter.  I'll check fuel pump pressure tomorrow, if I can figure out how and check the electrics for corrosion.  I wish I could get it in the shop quicker; I'd rather be surfing than working on the boat. :-)

Is there a port where you could thread in around the fuel filter or pump area to get a gauge on it to check pressure?

Did you change the fuel filter at the same time as the oil change or was the fuel filter change a reaction to the surging problem......just asking.......

I'm sure there is but I'll have to find it and then there's having a gauge that will hook up to it.

I changed it at the lake to try and solve the problem.

That happens to ours if we don't duct tape the fuel cap. I think it's water getting in the fuel.  I added a product called Heet https://www.goldeagle.com/product/heet-gas-line-antifreeze-water-remover that took care of it the last couple times it happened. 

I guess that's possible but it ran fine a few days before and has never happened before.

Gauge can be had at napa as well as the fittings. I would dump the Heet in there and see if it was water first, then move to fuel pressure. 

Plugs all look good? Hooked up? Not fouled etc? 

These are all the things your dealer is going to check...

X2 on the plug wires......not likely, but possible if you just changed oil.

I had a family emergency, so no time to check out the boat.  I'm dropping it at the Indmar service center tomorrow.  I'll let you know what the problem is when I find out.  Thanks, to all for the help.

It turns out that the leads on the Carter low pressure pump vibrated loose or were knocked loose.  My high pressure pump is also whining, so I'm thinking of changing it out before it dies.  I surfed today and it did fine except for one hiccup; we were surfing and all of a sudden the engine bogged down and it started surging again.  We shut it down and restarted and everything worked fine.  I had this problem a couple of years ago and the Indmar factory tech said to "run the hell out of it before and after surfing".  I've been doing that and everything has been fine until this fuel pump problem.  Anyone else have this happen?

Once it died, is it now a crank no start? Just cranks but won't start?

It always started ok and then would run out of fuel.  I wish you guys were closer; I've heard lots of good things.

I know you found your issue but just an fyi for anyone with surging issues on an old boat i had years ago i went through everything you could think of including pumping out the entire fuel tank. It ended up as a hairline crack in the porcline coating on one of the spark plugs that caused my issue and was hard to find.

Thanks for the update lakerat....I have the same boat/engine as you so I will try to remember your resolution!

I had the same thing happen on my Malibu.  It would run but start popping and missing at around 2000 rpm.  Chased everything and finally found the insulator cracks on 2 different Autolite plugs.  Found out later it was a known issue for them to split or crack after a few seasons.
