"Alarm Goes OffWhen I Press The Hotfoot"

Can anyone explain why an alarm goes off when I first press the hotfoot on my Yam HPDI - 250HP (2006 model)?? It stops after an initial beep.

Is the alarm constant or intermittent?

If intermittent it's probably water in the fuel filter. Empty the fuel filter.

PS> Make sure your boat has a fuel/water seperator on it. Yamaha installs them now but I don't know that your 06 boat has one. With the new ethanol gas you need the seperator. They're about $50 to have installed.

I am no mechanic-but just wondering. Would a weak oil pump cause this to happen when first giving it gas and then after a second or two pump enough oil to make alarm go off? Or would the design of the system not allow this to be able to happen?

Thanks a Million!!

also, check the oil reserve on the engine.

Thanks - I will try it ...

Hey K.D., can I add some type of water remover in the fuel tank and take care of the problem?

Also, make sure the oil is mixing with the fuel. Had the buzzer, sensor, oil pump, and about 5 other things go wrong on mine and POW!!!!! Have a new powerhead now.

hahahaha ... Sorry, I know that's no laughing matter, but the way you described it caught me off guard! That's certainly my worse fear - having to replace a POWER HEAD. I wish there was some magic potient for preventing that from occurring.
Thanks for the tip - I will certainly watch it!

Sorry if this reads like a book...

I work at a dealership. My answer to a customer would be to siphon and dispose of the old gas. This of course assumes the fuel is contaminated and also is a fail proof way of solving the problem with no exposure to risk. I'd suggest taking that same approach with your boat. It's one tank of gas vs. risking the life of the motor.

However if you have not had the fuel/water separator installed and intall one prior to running the motor further, it should catch the water in the fuel. You'd also have to empty the fuel filter to rid the fuel system of water. When DFW switched over to ethanol this became an issue for us suddenly because water sticks to ethanol and not to gasoline. Any water that used to be in the bottom of a tank was suddenly mixed with the ethanol and introduced to the motor. Yamaha has come out with the recommendation of the 10 micron fuel/water separator.

All of that is assuming that any water in the fuel is a small amount and incidental to your suddenly using ethanol gas. I read that you just bought the boat, so if you moved it from an area that doesn't use ethanol to an area that does this would create the problem you have. If you've pulled the old "i forgot to close the fuel door and took some water over the transom" trick and allowed water in the tank, empty the tank! http://www.bassboatcentral.com/smileys/Laugh.gif

If you haven't seen the fuel/water separator, it's blue and looks like an oil filter on a truck motor. Typically you'll see them by standing at the side of the boat and looking into the rigging compartment. Look towards the transom back under the fuel tank selector valve. If you see the blue filter back there it's already installed. If one is installed change it out.

If you need a picture of what Kelly is talking about, here it is... Highly recommend that you get one of these or the Racor brand version:

Check to see if you have one already installed. the replacement filters are about $20 and need to be replaced about once a year.
