    Default Years of reading the forums pays off

    Finally got my new boat out on the water for more than 5 minutes. Took a ride for about 20 minutes and came back to the dock. An hour later I get in the boat to trailer it. Turn the key, starts, sputters and dies. It just wouldn't start after that no matter what I did. The father in law, ex mechanic, listens to it and say "sounds like it's not getting gas". The light bulb on top of my head turns on. Take a look at the engine and I pour a bit of lake water on the fuel rails. Try to start it again and it fires, but starts running rough and dies after 10 or 20 seconds. Now I'm sure I know whats wrong. I follow the supply line to the fuel pump, get some lake water and pour it on the pump. I turn the key and, like magic, the motor starts and runs as smooth as it ever did. Problem solved.

    Thanks to years of going through the various problems and solutions people have posted, I remembered that some of you have had "vapor lock" issues and a little bit of cool water resolved your issues.

    It could also be magic water. You are from the land of sky blue waters. I'm glad our troubles was your fix.

    Sorry to hear about it! I too have been dealing with the issue and used this forum (while on the water) to get back underway. My boat is currently on the way back from the dealership after having Indmar's additional boost pump installed. I'm taking it out tonight to test everything out. I'll let you know how it does.

    I've never had the issue, but should it arise where exactly do you pour cold water? Admittedly I've never looked for the fuel pump.

    Taft, your fuel pump should be located in the actual fuel tank so the fuel on board should keep it cool and prevent you from having this problem. I think this was mainly an issue on the 07 and older boats, my 08 has a fuel tank mounted pump and it doesnt get much hotter than the Texas summer and I never have an issue with this.

    Does the manufacturer have a modification that can be done on these older boats? If not, I just might rig up a "sprinkler/sprayer" of some sort to a switch under the dash.
    It's only the 3'rd time I've had the boat on the water and don't want to have to be opening up hatches every time this happens. Base on what I've seen this probably happens more often than not.
    Not a big deal and an easy fix at any rate. Just a bit of time to do the work only once.

    Inexpensive fix I got from my dealer....change your fuel filter every year. Use mid grade fuel and add an additive such as Sta Bil Marine at every fill up to fight the ethanol issue that is the primary cause of the problem. I vapor locked for 2 summers in hot weather until I followed this procedure. Never had another issue.

    OK. I've got 2 out of 3. I'm using mid grade, it's called for in the manual. I've got sta bil in the gas, double the dosage actually. Drawback is it's the gas from last fall, and the tank still reads full. When I fill up next time I'll add sta bil, as I usually don't use this in the middle of the summer. We'll see what happens.
