Re: HP Question

Fish, I appreciate your enthusiasm for the 496. But one thing you are not considering is that anecdotal evidence indicates there is a problem with my motor, whether it is fuel starvation, a tired motor or an ECM issue. This was confirmed by WaterWalker (if you recall, my engine should not be losing ...

Re: need prop help

Ask blackwaterairboats what prop he is running. He has a 19x8 tour boat (seating for 9 plus driver) with a 607 HP 496 that leaps out of the water. He claims top speed over 70 and after riding on it, I don't doubt that for a second. I also will say that his prop is waaaaayyyy quieter than my Maximus ...

You are moving in the right direction, there is some people you just have to pay no mind too. I'm not a newcomer to forums in general; just a newcomer to owning an airboat. There will always be someone that has to weigh in on the discussion that has absolutely nothing to add to it. The cream always...

Re: HP Question

Hey digginfool don't forget that no matter how much horsepower your engine has or how much thrust your motor can make if you find that mud unexpectedly you might not be in the driver's seat anymore so be careful. When the water gets low in 2A it's some crazy riding from what I've experienced. Slide...

Re: HP Question

Thanks again David. However, I'm not an 'operating engineer' but I certainly could have thought it through enough to solve the answer to my question on my own. Being the manufacturer, I felt it easier to ask for information you would have readily available. FYI, I am a civil engineer (BSCE). My scre...

Re: HP Question

When you took me for a ride in your boat yesterday, that is the type of performance I expect from an airboat; jumps right on plane, responds with throttle and makes an otherwise heavy boat feel light. My step-dad's boat was 11 or 12 feet with an O-360. Your boat felt like what I remember how his boa...

Re: HP Question

This is more along the lines of the type of information I'm looking for. Your description of how the prop behaves validates what blackwaterairboats and pipedog related to me while we were hauling rock yesterday. While it is counter-intuitive to me, real world experience says otherwise. Some of the p...

You actually have quite the opposite impression of my quest. If you go back to my OP, you will see that I was asking if it is worthwhile to add power or are you just getting 'bragging rights.'

Thank you for weighing in, David. Being an engineer, I'm quite familiar with Occam's Razor. A phone call to someone at Water Walker was definitely coming.

Re: Hunting lease

Back in the day, Deseret was strictly Mormon land; you definitely didn't want to get caught out there hunting. My step-dad used to take me hunting out on Hog Island. That was the closest we ever got to hunt those lands. Glad to see they're spreading the love around. :)

Re: HP Question

Is prop governing your engine or is the computer programmed to govern the engine at 5150 RPM? :) Ok. I see where you are coming from. I would have to say the prop is governing the propeller. I don't believe a rev limiter is the issue. How do you know??? :) I'm not playing that game. I've already ex...

Re: HP Question

Is prop governing your engine or is the computer programmed to govern the engine at 5150 RPM? The difference in adding a 2.52 ratio and 2" of blade length is way huge. But if you don't have enough pitch in your prop to govern the engine the computer is doing the governing. I am not guessing about t...

Re: HP Question

Let me clarify a few items about your post, fish. I appreciate your input but you seem to be missing the point. First, the prop's maximum recommended speed is 2,200 RPM. With my gear box and WOT RPM of 5,150 RPM, the prop is turning 2,164 RPM. I doubt 36 more RPM is going to change much regarding th...

Your motor should truly be a 425hp and 500 torque. I have had two of the same motors the only difference is mine were a pleasure craft marine motor. My new motor is 607hp and 664 torque my boat is 18x8 and holds 9 people plus me and holds 50 gals of gas. My boat will run 80mph and will go just abou...

Re: HP Question

BTW, even though Marine Power says the motor is 465 HP, the people at Raylar said that the motor came from GM rated at 420 HP and somebody at Marine Power most likely figured the headers added 45 HP and marketed the engine as having 465. They doubt it has much more than the OEM rating of 420.

Re: HP Question

There are several posts on here regarding good design parameters for airboats and almost universally, the rule of thumb is 3 - 4 lbs of boat & gear per HP (I did see one suggestion of 4 - 6 lbs per HP). If you consider my boat, it seats seven and has the 496 BBC (8.1 Vortec) with gearbox and prop. T...

Re: HP Question

I do not know if you can get a hub to equal 80" in 4 blades using your current Maximus blade. You have an amazing propeller for low end push. Again, the 2.5 ratio will help you with ground running. A long hub will yield you an 82" 3 blade. 1" closer to the cage. 2" total length longer going to a lo...

After a long weekend in the Keys, more questions. My target is the 600 - 650 HP range. It seems the easiest way to get there is with a supercharger.

Where is my thinking wrong. Wouldn't a 2.68 gear box be the first place to start, then go with different blades then address the motor. Not questioning your knowledge but why would I want to slow my blades down? I can do that with throttle. And as far as blades, I'm already turning pretty large bla...

Re: HP Question

great box , but for a 496 , horsepower of 465 is rather mild for todays standards. A bolder profile cam and good roller lifters could really bring that BB alive. Brother in law just finished a 496 for another member that rides with us. Its a conservative 600 + hp . Its on a 16 x 8 high side DB with...
