    Re: 4-cycle snowmobile engine?

    Thanks a bunch for that J-bird link. That's just a 5-hour drive from me, so I could run over there with my engine for a fitting.
    I'll check out Arrow Prop, too. I have a link saved for an outfit...

    Re: 4-cycle snowmobile engine?

    Well, the setup is similar to what I had visualized. That wood pulley is unique.
    Hmmmm......maybe a cog belt is in the future. With the advent of relatively cheap blower drive pulleys available, a...

    Re: 4-cycle snowmobile engine?

    Well, Bart; I don't have it in my possession yet. Been a bit busy with remodeling a few rooms in the house. I should get out and get it home before a scrapper gets it from a local tow yard.

    I'm...

    Re: 4-cycle snowmobile engine?

    Well, I figured it might be a long shot. I suspect a huge majority of you live in the southern states, and have never seen a snowmobile, much less up close.

    I had to try, anyway.

    4-cycle snowmobile engine?

    Looking for a little advice.
    I have the opportunity to pick up an Artic Cat, 4 cycle snowmobile engine, (actually the whole sled), for a mere $50.
    I'm thinking it might make a suitable mini airboat...

    Ain't it great having a metal lathe just waiting for you to turn something out as needed? :-D;thumb;

    Re: OIL PLUG modification

    Will this modified plug be the only drain point available for oil changes? If so, I recommend steel or brass, instead of aluminum. Aluminum, being soft, has a greater chance of galling and locking...

    You might want to investigate how much RPM that plastic fan blade can handle.

    Hmmm. 4:10's behind a six banger? I thought that was a 3:73 ratio, or thereabouts.
    Not exactly the best way to make a score, but it sounds like you came up roses on that one.
    Looks like an air box...

    You're saying that the welder completed it's needed circuit through the Jeep wiring? That seems rather unusual, but possible. Bad luck for you.

    Re: steering and cage size

    Eric; keep in mind that the bigger the prop, the higher up you'll have to mount it. That will move weight higher on the hull, thus resulting in a top-heavy condition. I'll guess that you don't want...

    Re: How do flooded boats float, foam , air spaces ?

    You're right, the foam does add weight to the boat. It also keeps water out of those spaces, in a general sense. The foam captures air in thousands of small cells, thus eliminating the ability for...

    Re: Identification help?

    Yeah.....the seat height was the first thing I noticed. If that thing turns turtle, you'd need an airlift to get it out of the mud.

    They might be thinking it got dropped in transit, and they'd rather be safe than sorry, if there's a small crack starting in the block.

    I've had this idea in my shoulder-mounted vacuum chamber for awhile, but I'm just an "eyeball engineer", and it might be wise to seek the advice of others more experienced than I.
