    1978 Wetbike Rebuild

    Some of you might know what these are, most of you probably don't.

    I picked up a 1978 Suzuki / Aquanautix (surprisingly, mine has "Division of Arctic Enterprises" sticker on it!) wetbike last weekend.






    These are jet powered and ride up on plane on the two ski's you can see below it. They have either a 50 or 60HP suzuki watercooled twin engine. I got lucky with mine and it had 150PSI in both holes, which is dead on for stockers. Not bad for something 30 years old!

    It does need a little work. It turns over, but won't start for some reason, and it's blowing fuses. Doesn't seem to be getting fuel through the lines either, so time to dig in. It's also going to get a new seat cover and new paint.

    Re: 1978 Wetbike Rebuild

    here's the daily update (I actually did this stuff last night, but figured I'd do the post in sections so you can see how I progressed.)

    I figured out the tangled mess of wires under the dash and got the whole thing re-wired.



    It's still a little ugly, but I'll go back through and clean it up again tonight. (especially the red jumpers with the big glob of tape on them. going to re-make that piece) I forgot to take a before picture.

    Here's the panel from the top. Stock, these came with a key and no lanyard. I thought a lanyard would be a good idea. The other two buttons are a momentary SPST for the starter and SPST for the electric choke.



    remember the comment about blowing fuses? One of the weird things with the early versions is that they came with a blower to clear out the hull. Good idea, except the exhaust ports blow the fumes right into the drivers face. Also, I found out that someone didn't do too good of a job with wiring.



    no wonder I was smoking fuses. The insulation on the joints was pulled back far enough that the two wires had fused themselves togethor. Note to anyone out there - if you are going to solder wires togethor, cut one shorter than the other by about 3 inches. This prevents the solder joints from coming in contact with each other if the insulation falls apart.

    Electrical is done, except for the cleanup. I have spark, turns over, and doesn't blow fuses. Oh yeah, the choke and bilge pump work now too.

    Time to fix the fuel system.

    Since this thing is so old, the original fuel pickup was gone.

    Again, i forgot to take a before picture, but it was basically a twin barbed setup with a piece of nylon tube going into the tank, and a barb for the fuel line on the top. POS!

    Here's what it looks like now. $10 in parts from ACE hardware (thanks Tony for the help!)



    It is basically a 1/4" piece of brass tubing about 13 inches long, with a curve in it (pickup)

    On the top of the tank is a 1/4" compression fitting that the tube psases through, and then into another 1/4" compression fitting that the 90* barb is threaded onto. No more rotting plastic! I use an inline fuel filter instead of a strainer in the tank. Easier to clean / replace.

    now I have a sealed system, getting fuel, and guess what, she lives!

    Re: 1978 Wetbike Rebuild

    Todays project is going to be the seat. My wonderful wife has agreed to help re-upholster it for me, and for once, I have before pictures.

    Here's what I'm starting with.



    Seat un-duct-taped from the hull material



    Going to get some new mounting bolts, vinyle and padding, and start the re-work process tonight.

    Good Job!!

    Ive seen plenty of these, 60 and 50hp, as my bro in-law colect and restores them.
    I always thought he only starts the blower before starting the engine and not while in motion, but who knows. I can barely drive one of these. Real tricky machine but lots of fun.

    Don't forget the anti-drainback valve (spring-loaded ball valve) in the fuel line.

    Andy should have one if one didn't come with your setup.
