How big a boat is that v6 pushing?

What RPM you spinning up ?

You can start by measuring the prop length then look for an embossed stamping on the prop for an ID or reference.

Like Junk said it could be one of those boats built to stay in the water.

The best way is give us enough information so that we have more than a remote clue about what you are working with.
You have an idea what you have, but we don't. An airboat with a V6, is a pretty vague description. :dontknow:

How long is the hull? How wide? 'Glass or aluminum?
What material is the rigging and cage made from? Seating?
Is it direct drive or have a gearbox? And not least importantly, what V6 ?
How many RPMs will it turn that prop? How long is the prop? How wide?

Posting some pictures as Junker suggested would be a big help, as would supplying the above info.

There are a small handful of those V6s hereabouts that run well enough to surprise most folks;
but they are most likely not stock, nor are they excessively large and/or heavy.

If it is direct drive and not been on a diet, Junker's assessment may very well be on the mark.

bigstuff; try putting into water first. have some fun--get used to the boat, and then work your way up to running up on the bank a little at a time. I run a 4.3 chevvy w/blue lightning drive, and water-walker prop on a 13 ft boat. I can run dry but, be very carefull on my leaves. if not for the drive, I wouldn't be able to run dry at all. sounds like that's where you are.

The only car engine I have ever seen that can run dry without a gearbox is a caddy.

yea and not as good as an aircraft. I can say its still nice to have a boat. I ran a dd350 for years. Now a gear box will change things.
