340 CAT ETX intermittent surging with 3000 RPM limit or it'll die and not start

It was still probably cheaper than paying diagnosis time and MSRP for parts at the dealer.

I agree

Most definitely! Glad it’s up and running again... like I said, ignition coils can cause some weird and highly irritating symptoms that sometimes make you look in a totally different direction. Glad to see you just did it all and found some potential future problems to fix at the same time! That could be a major save in the long run.

Now you have a good running boat to sell and you can come grab my SA! Lol
Or hell, I’ll even deliver...

I have an idea! Trayson should buy my Max and I’ll buy the SA.

So I was out yesterday for the first run of the season. Boat died on the wife shortly after launching. I didn't think too much of it. We went to our play spot (20 minutes), chilled out, filled ballast, surfed a session. Then we were draining ballast and needed to move from where we were drifting. The boat died and wouldn't start again. it would crank, sputter up and die.

So I figured out that I wasn't hearing the fuel pump prime upon key turn. (this happened a week ago at home, but the next day it worked fine).

I started messing with wires and after trying a few places of moving around wires and sensors, I wiggled around the wires that were attaching to the bottom of the low pressure fuel pump. After that, I had the wife try the key and sure enough the pump buzzed to life priming up and we were able to start and drive no problem. It cut out once on the drive back, but we were able to get back just fine.

So tonight I'm going to take a look at those connections and see if making them bomber will remedy that aspect I've been having trouble with for so long... So in the end it's likely that my issues were a combination of factors. Here's to hoping that I've found the final piece.

That's what I keep telling myself! (it's sure cheaper than a boat payment on anything newer!)

That said, I surfed my boat yesterday and last month I was on my buddy's 2015 Centurion FS23 with piggyback bags... I'll take my wave all day.
