    I was wondering if someone happens to know approximatly what the engine and jet drive from the old kawasaki 300cc or 440cc jet ski weights? ( or other smaller jet ski/waverunner/seadoo)

    Sorry Hoyt, but I have to call BS on this one.

    I would think the combo to be in the neighbourhood of 200 pounds.

    My whole Yamaha RZ350 motorcycle only weighs 350 pounds.

    That 300x has a 1500 cc engine and probably the1080 is the fully loaded weight of the whole boat. The engine I would guess is probably 1/3 of that. For a 300 cc motor I would guess less than 80 lbs.

    Sorry. I misread. You're right. The whole thing weighs 1080 not just the engine. I will blame tired eye and try to find the correct answer. Post corrected.

    I could not find the weight of the engine/jet. I tried. Good luck.

    80lbs would be close on I have seen them and I reckon I could pick it up and walk about with it. So 50 kilo would be my guess.

    Maybe ask on a forum that pertains to these?

    Planning on using one in a boat?

    Some of the guys are getting their alloy boat, motor, pump to weigh in at about 500#'s all up. Light enough so that 2 bigger guys can lift it back into the water after an 'overland excersion'!

    G'day Kiwi,
    I hope you enjoyed the match at Twickenham last weekend. I certainly did.
    My mate has a winch and a chainsaw in his jet boat in Central Otago.

    75kg or less is my guess for the motor plus drive.
    Cheers

    Sorry, I don't generally watch ball sports. Though I did notice we have the Webb Ellis cup at the moment!

    Yeah, a chainsaw and winch can be pretty standard practice here. Saw just recently one of the guys had adapted a capstan and gearbox to bolt onto his saw in place of the chain.

    Remember that a pwc has the tunnel cast into the hull rather than a stand alone bolt in item, so depending on what you are doing the weight of this may need to be considered along with the weight if entrained water also

    Hi all,

    The kawi 300 single cyl is a neet little engine and make's 1 more hp than the 440. With a pipe, carb and head mil you will have some where round 40 hp.
    Being a single cyl it's not as smooth as a twin.

    300 cc - pump, ebox and engine = 50 pounds

    440 to 800 cc's - pump, ebox and engine = 85 to 110 pounds

    I have a newer 1000cc 4 stroke on the table and would guess its around 200 plus lb's.

    www.pwctoday.com is your best resource for the older kawasaki skis, go to the "vintage" section rather than the kawasaki section

    the 300cc is a tiny little motor, scary reliable too - but may be a bit underpowered for your project

    the 440 has one less horsepower than a 300cc in its stock configuration, it responds very well to cheap bolt on improvements

    the 550 is very nearly the same weight as the 440, it is a 440 motor with larger pistons and is probably your best bet if you're planning a budget build - you can get a complete motor in the $300 range

    from 650-800 the kawasaki motors are all roughly the same weight size and shape

    from what i've heard the yamaha pumps are better designed, but are going to run a little more $$
