Get real clear in your mind what you think is "peak RPM vs torque" because

Re: Old airboat, new driver, and problems

I have no doubt at all about Swamphunter being correct with his estimations. Unless I had a trusted confirmation from somebody who claims to know more about those specifics than I do, I would use the correct 454 OEM pieces. They may well be the same and then again likely they are not; I don't know e...

Re: New to airboat - need advice

Although I agree with most of the above, like for instance the 500 was exclusive and specific to the Cadillac El Dorado which they stopped making in 75 not 76. . . I know a little bit about this stuff because my boat is named El Dorado for a reason. No intention to offend, but years ago there was a...

Re: Old airboat, new driver, and problems

. . . The old 454 DD was set up with a flex plate and my engine guy is wondering if we should go back with that or upgrade to a flywheel. Any thoughts?

That isn't something I could confirm or deny with that engine. However, based on my
Caddy experience, that certainly does not sound to be outside the realm of possibility.

That is good news then . . . it ain't a 425. 8) .. It is worth confirming that 4th digit is a 6, could be a 5. 148 6 200 would be a later model, and consequently, lower compression (most likely) 500.

Re: A man's word

What I meant was that the stock weight for the engine you looked up, likely included the factory intake.
Since, this one already has aluminum the weight difference would not be as large as that number would seem to imply.

There is no question that is a valid concern, and one that is admittedly more than passively relevant. Aft beam and freeboard would both be a consideration, as would operator experience. ..

Re: New to airboat - need advice

While all that is both needed and relevant information, You really first need to take a little time and identify what the engine really is. There was no 500 made until '70. If the year is correct and it's a '69, then it is a high compression 472. If the 500 cid is correct, it could be anywhere from ...

Re: rudders

It's a shame that you didn't pose the question before you cut them off. There is no harm and little thrust penalty to be paid for having the prop dip below the top of the transom. Hopefully you haven't noticed a large difference in the amount of push you are seeing. As far as your rudders vs maneuve...
