    Question Yamaha vx cruiser 2008 issues

    Hi guys, I was wondering if someone would be kind enough to offer me some tips. MY 2008 vx cruiser loses power when trying to get out of water with two people, often 'skips' when full throttle, cuts out idling. Two professional yamaha shops have serviced it on three ooccasionsin 12 months. Every time saying there is nothing wrong with it. It's not my imagination. In frustration I drained all fuel, put in new fuel from a newly opened service station, replaced battery and put in jet cleaner (into fuel) high octane 96 fuel insteadof 94 . It went like an absolute dream. I took it out yesterday a week later when I got down to half a tank it started playing up again... Same issues. It feels like a fuel issue but I know nothing at all about jetski and really need some guidance. The service agents for yamaha clearly have no idea and I'd really like to be comfortable taking it out more. At the moment everyone tells meto sell it and get a boat iinstead. Any help you could offer would be appreciated. I love my jetski and maybe it's something really simple to fix??

    i had a long response to this thread and out of nowhere my browser crashed and lost it all.....shiiit...



    You need to remove the fuel pump from the ski, get an impact drive and a 10mm socket and take the tank bracket all off. Youll need to finagle the assembly out of the tank, itll take some twisting and turning. Once you get it all apart, spray the filter down with carb and choke spray and make sure everything else is spotless. Now is a good time to get you iphone with video and your flash on, and do a quick film of the inside of the tank. more importantly the bottom of the tank, to see if there is a layer of dirt, debris slime or sludge. Ive used hand pumps with a tickle sticks attached to the hose to clean tanks before and a few other methods, but you really need to get into it...

    If you havnt already done this, replace you air filter. They sell k &n filter for 50 bucks and they are reusable.

    take your injectors off and clean them as well. Be sure to install all 4 injectors in the rail carefully first , and then lower them over on the manifold, or you'll break your o rings.

    If you want to really get into it. Remove the harness off the top of the intake manifold and set it off to the side. There are two 12 mm bolts that are just under the black intake manifold that hold it to the block, and 4 rubber intake runners that need a tiny socket to remove (dont know off the top of my head) and if you lift up you can take the whole thing off. Then plug the 4 holes up with paper towels and remove your Throttle body and clean the crap out of it.


    Behind that is a honey comb looking filter that either needs to get a serious dose of carb and chose spray or removed all together. You want to clean the entire intake thoroughly so plan at least 3/4 of a can for it. Get it nice and clean. And reassemble.

    Since it seems your ski needs a good cleaning, once you do all this, itll probably run like it did when new.


    oh spark plugs, if they arent new, get a fresh set.

    Oh gosh

    GOSH, I am no mechanic. Do you know what that might cost to have the shop do? It sounds like major repairs. I'm already feeling a littleripped off from the Yamaha service agents. Is it something that if you couldn't do yourself would cost more than ski is worth?

    Personally i can do this all in under an hour, but ive done is 16,999 time before. but at a shop theyll likely charge 3. Hard to say, sometimes they just dont give a shit and will make up reasons why they cant.

    Ok thanks so much for that. I was thinking couple of days work and lots $ but now I know 1-3 hours as a guide I'm less likely to be ripped off. Again thank you. Most kind to reply
