need help fast!!!

[treyfry]

my boat is at the dealership, where i bought it at getting some work done. i took it out friday and could not get it to stay planned off. it would get up then just drown out to nothing. at full speed i only got 4500 rpm where i usually get 5800. the guy said it was a fuel injector and it was covered under warrenty. now he says its bad fuel and that my lines and injectors are gunked up, and that it needs to be taken apart and cleaned. he also says that this is not covered under warrenty and it gonna cost me 300 dollars. the motor is a 2009 yamaha 4 stroke with 75 hours, i have had it for 2 and a half months and the longest it has set up is maybe ten days. is this possible or is he trying to rip me off? any help will be greatly appriciated!!

Man that sure sounds fishy!
Any way to get a second opinion?
Symptoms sound like a fuel delivery problem, how are your filters set up on your fuel lines?
Any chance that some kind of dirt has bypassed your filters?
Usually the filters clog up first, causing starving symptoms, changing them usually will clear up the problem.
It seems like it is too soon to experience injector problems, unless you don't have any kind of fuel filters in line?
Two months is like brand new...

with the U.S. making corn ethanol this has happened to a bunch of people. The fuel in your tank has gone through a phase separation which in fuel terms now days it has become crap! the motor company's do not warranty no fuel related problems....! it is costing people time, money , lost vacations, crappy running boats, engine problems, etc... sorry to be the one that's writing this also. YOU should now be checking your filters and changing them on a reguar basis when you use your boat. keep extra filters onboard all the time also. take a clear glass jar (pickle jar, jelly jar kinda thing and unscrew your filter and dump back into the jar).. see what you have before you let anyone work on it. also make sure they clean out your vst tank and run some fuel through all the lines before it goes back together and make damn sure your hoses are not coming apart from the inside out.. you can also polish your fuel in your tank or suck it out... we have been though this before. start useing some startron or starbrite stuff and run some sea foam through her time to time napa carries it. it's ethanol and it was never intended for marine or lawn mowers... drink rum and take it as a grain of salt.. in an open wound!!! learn to do this service yourself it is not that hard. get your engine book...learn it and understand that your fuel lines can also be the problem.

treyfry.....if you have fiberglass fuel tanks...the ethanol issue may very well be your problem....as well as another major problem in your near future. If your tank is fiberglass and has started to breakdown, you will need to change your fuel tank or this will continue to happen until it fails and starts to leak.

If your tank is not fiberglass, this is not your problem. Check your fuel filters before letting the dealer do the cleanout. I'd hate to see you pay $300 for just changing the filters. The ethanol fuels attract water, so if the tanks have been sitting a while, they probably have some water in them and have begun to clog the filters.

thanks for all replies, i have an aluminum tank so its not the tank. i met with the yamaha service rep for the dealership i went through yesterday. he shot me straight, the guys in the shop said it was clogged and gummed up. the yamaha guy said that it was only one fuel infector that was clogged somehow. after a long talk the rep agreed to cover the cleaning and fixing of that one injector. i lust had a big problem with spending three hundred dollars to fix a brand new boat. he also said the same things you guys did, to put fuel stabilizer in my gas, dont use ethanol, and he is going to show me how the clean it my self today. the guys in the shop tried to rip me, luckly the yamaha guy was a good one and told me the truth, im meeting with them again after lunch, ill keep you guys posted on what happens. again thanks for the help.

It sounds like the dealer was trying to pocket a little extra gas money for the weekend. The ethanol issue sounds fishy 2 months old and its only sat for 10 days at most. sounds like crap to me. The Yammie rep did good by you.

I am a marine technician and have run into this very problem. Where the Yamaha rep could be right, if your other injectors are fine now, why have them cleaned? Remember this, if you had fuel that somehow contaminated one injector @ one point, it doesn't mean that others aren't close to follow. Same fuel supply right?

put in two cans of sea foam. had same thing with my optimax, both did the same so now in put a can in it when i gas up.

Ethanol sucks no doubt about it........this is where the guys trailering their boats have an advantage over guys that slip their boats, after having to pump out 40 gallons of bad fuel and having the carb rebuilt for the second time in 2 months we have had our fill of bad gas.....all it takes is one fill up of bad fuel and it gets expensive in a hurry, if your filling up on the water wait till the end of the day or at least mid day....let the early birds get all the crap that separated over night and deal with the issues that come with it.
