    Project js550 and js440

    Hey all,

    Newbie here, thought I'd share my new winter projects.
    A 1979 js440 and a 1987 js550, including a galvanized shoreland'r trailer picked up for $700.

    The kicker, neither start.

    This will be my first restoration and I have no hands-on experience with engines, but I'm reading up all the great material available on this forum.

    Compression tested out evenly at 165psi (js440, recently rebuilt) and 135psi (js550) and I found a broken wet exhaust hose, but otherwise I know nothing. Physically the skis seem to be in just okay condition, the js440 being cleaner. Both are poorly painted so I will give them a hobbyist best paint job, hoping not to find fiberglass damage.

    Carb rebuild kits are in the mail (bn-38 and bn-44) and I added some flush hoses; keep you posted.

    Anyway, I certainly appreciate any and all advise or suggestions along the way.

    Cheers

    Don't like how someone RTV'd instead of installing gaskets.....

    Re: Project js550 and js440

    Sounds like RTV is a no-go and will need to be rebuilt.

    If anyone has suggestions on any tests I should run before dissembling the engines or tips on how to tackle the projects entirely, I'm all ears. Currently reading through the manual ("Kawasaki PWC Repair Manual 73-91"). Ultimately I want to do an entire over-haul of all gaskets/bearings/seals. My plan of attack is to get the skis running after rebuilding the carbs (hopefully) and identify any other major issues like electrical, before dissembling.

    As far as parts go, are SBT kits acceptable replacements for OEM?

    After my hands get dirty I'll be posting my progress here.

    Re: Project js550 and js440

    Real question here is how much are you willing to spend, and what are your expectations?
    When I was able to afford the sport and already knew I loved the js hull, I wish I went all out instead of replacing, adding and rebuilding on a motor that now sits in a landfill.

    Maaaany of us enough have parts laying around and are willing to sell for the price of postage and a beer for you to get on the water and see how much you like riding.

    You may end up just saving yourself from spending money on something you're not into. You can than use that money for raincoats, umbrellas and coffee, or whatever you Washington people buy.
    You can't drink all day, if you don't start in the morning.

    Re: Project js550 and js440

    Here in Washington I've spent enough on coats and coffee, I'll be okay spending some money on a fun summer project.

    Expectation is a fun nimble ski, easily/cheaply repairable, that I can learn to wrench on, and won't leave me stranded in the lake. Learning to wrench on my own engines is a big part, so I thought these could be great starter projects.

    I haven't ridden a js hull, but I have been riding my other new-to-me stand-up, which is a blast (750sxi pro). My preference will be for restoration quality over performance.

    The "Parts for Sale" thread is going to be super helpful
