The boat I'm restoring has a mark near the bottom of the tank that says "5".
I'm assuming it's a 5 gallon mark. Well today is the 1st time I've been able to stretch the motor out and really run it.
Here's what went down, be patient with my storytelling :blah blah blah
Launched the boat with about 3" of fuel about that "5" mark. Motor ran perfect for several passes and I"d say at least 15-20 minutes of steady running with a few stops and starts in between. Motor starts "stuttering" or "cutting out" at high rpms, then later at lower rpms too. So, I look around and notice that I"m about 1" below that "5" mark. I don't think anything about it considering there is a few gallons of fuel left.
I go buy new plugs and a new fuel line (needed them anyway), dump 6 gallons of fuel in it and head back to the river. The motor runs perfect, turned a 28 hrydromotive quad iv to 6k and 81+ mph. Had my son with me so didn't trim it out.
Well, I run it for about 15 minutes or so and right before leaving, it starts the same "stuttering" and "cutting out". It's not constant, but very noticeable. So, in looking around I notice that the fuel level was very close to 1" below that "5" mark.
I get home and pull the pick up tube out of the tank and measuring it against the fuel level, the pick up is about an 1" below the fuel level where it was cutting out. No visible cracks or splits in tube.
Is it possible that the fuel is sloshing around even though it's still 1" above the bottom of the pick up tube and starving the motor?
Or is this a weird coincidence and something else is going on?
