Well last week the motor was bogging, pulled the high speed jets and wow great back to normal. Yesterday I was on the water and the motor started acting up, it was very hard to start to the point of almost draining both my batteries. once it started I can open it up and then about 2 minutes the RMP's dropped and the motor stalled. And it did this about 10 times until I got it back to the dock. One thing i noticed was a semi loud ticking noise, I stopped the engine and pulled the cover. It was the VRO pump ticking, it was making a noise like a bad lifter. As so as I squeezed the ball she would stop ticking and then start a couple of minutes later.

I have disconnected the VRO and running premix instead. Anyone have a clue what this can be? I plan on pulling the carbs for a fourth time. Last time I pulled them there was like a green/bluish foam in the carbs, you can see it as soon as you pull off the silencer cover. I thought it was probably crap leftover after using the seafoam. Also this boat sat for about 3-4 years before I bought it. So the 35 gallon tank under the deck had alot of gas left in it so when I redid the floor I was able to pull the tank and drain it. Perhaps after this first full tank of gas it may have loosened up stuff in the tank?

Thanks
Jeremy

That greenish foam in the silencer and carbs sounds like water in the fuel to me..

hope you are using a fuel water separator canister filter, with a built in tank. it catches all that crap. you very well have picked up stuff from the tank, check filter, filter on fuel pump, and blow air in the the tank pickup tube. it has a screen on it, that could be clogging. did the primer bulp go flat?

Thanks for the info. Yes I do have a water seperator. I will change that out today. I replaced the filter just before this first tank of gas. The primer never went flat on me it was always hard, just when I squeezed it the VRO stopped ticking.

I will check all the other filters as well. So from what I understand it sounds like a water/fuel mixture.

Also what is the best way to tell when to change the seperator filter?

Thanks again.
