150HP Yamaha V6 Precision 2 Stroke Water in the carbs

[fcorey]

I have brought my boat in for servicing to a local mechanic.

Last week I was out fishing with my buddy and we ran a 12 gallon gas tank empty and the boat stalled on the way back. I had a spare fuel can and filled up the tank. The boat started right away but then puttered out and I could not get it to start again. I assumed I had sucked water into the carbs and had the the mechanic pick it up and asked him to clean the carbs and purge any water out of the motor.

I don't have all the details yet but this mechanic is telling me that because I sucked this small amount of water into the carbs my entire motor is a write off. The strange thing is this boat sunk 2 years earlier and the motor spent 48 hours completely submerged in saltwater. The mechanic who I used back then was able to clean everything out and have the motor in perfect running condition the next day. I find this very strange that my motor is all of a sudden a write off from sucking a small amount of water from the bottom of a 12 gallon tank into the carbs.

Any direction from some Yamaha outboard motor savvy people would be greatly appreciated.

I don't doubt that the carbs need cleaning after ingesting the water, but unless the motor seized, locked up or blew a piston, there should be no reason to think that it's totally shot. Maybe the guy wants to sell you a motor. Good Luck!

key here is the speed at which the water was removed after air exposure.
in the case of the submersion it was immediate, in the case of pulling in watery fuel and letting it sit a week or longer may be the difference.

if we are checking the carbs two or three day after they got water, I would just open the drain plug at the bottom of every carb and pump the bulb until you see fresh gas out of them, take the spark plugs out ,clean them or replace them ...I'm sure the motor will fire up right away ...but if we are talking about two or three weeks them you will need to pull the carb and clean them ...trach motor...hummm..I would find another mechanic
