looks like an offshore version of the briggs family of engines and there lots of them on boats as Country says . Better to stay with the briggs . JMO . I,m considering this route for my next boat . Country ; what say yee about engine mods to the 35 briggs ? heads , rods and pistons , cam , carbs an...

John ..I was out of town this weekend .. so didnt get back to you .. they are tellin you right .. 4 is not enough

with a belt reduction of around 1.69 which you can get from arrow props .. and a 3 blade warpdrive that they recommend it is viable you can find plenty of info in the mini boat section with a quick search

if it works .. but is touchy .. you need to change the pivot point so the throw is longer .. you can scale a model size design out of popsicle sticks to get it to your liking ..

"supposedly the ECOtech's have more power than a Briggs" REALLY Country? Can I educate you? I'm turning the SAME propeller as you would on a Lycoming 540. :banghead: nope you can't educate me .. I only said supposedly because I don't have first hand experience and figured somebody would get their p...

mini's are great if you plan on using them as a boat and not as a 4x4 ... supposedly the ecotechs get better mileage than a briggs ?? and have more power ?? Glad you are enjoying it

yep they sell hunting club leases/memberships .. and there is always the back gate low light method .. LOL but there are some who can tell you first hand that getting caught is usually a very bad azzwhoopin and possibly a trip to jail ,,,

more and more boats .. with more and more power .. drivers with less and less stick time before they get the hotrod boats .. easily spells disaster. Whats the solution ?? obviously common sense .. but it isnt so common as some would think. Throw in a little alcohol and a sense of being free to drive...

very sad to hear ... I sent a lot of folks to him for parts .. he was always very nice and patient .. hell of a great guy .. certainly will be missed by all

RIP and slide on easy man

yeah it was guys .. well there is always next time ... LOL

Look ... we all know you can't trust no lasers ... cell phone stopwatches are way more gooder .. especially when you are only at one end of the track or the other .. kinda hard to be at both ends unless you on the boat don't ya know ..

ALRIGHT .. that looks sharp ... and has a good ring to it as well ..

LOL and besides the longer we can keep this thread going the more cheerleading for WHIRLWIND ... as they say .. SIMPLY THE BEST .. don't believe it ?? just look in their ad in any airboat magazine .. it is written so it has to be true .. and I believe it too ... In my next life maybe I be a poet .. ...

Old .. smold .. aint nothin but mold .. can't live in the past gotta live the present .. next time STEPPN UPP may be second or third .. but right now he is the fastest in the land ... he is the one to beat ... yeah Bubba it is good to be back .. I got enough internet gas money for at least two month...

hey guys there was no BS in my original post ... go back and read it ... ......... Razors and sabers are hollow .. warps are solid .. so warps might survive a light strike better .. maybe Razors and saber take more power per blade so you probably won't run 5 of them as for which is better .. my vote...

this is more like it .. like the old days .. on SA .. and it only took one stir of the pot with a little help from tony480 .. hope y'all enjoyed it .. I DID ..

LOL maybe I should just say I think the fastest airboats in the world run whirlwinds ??? groundrattler and steppn upp .. ??? I don't know y'all tell me .. I know thunder used to run sensenitch props .. but he is all washed up in unlimited I believe .. or is he makin a comeback also ??? or heck maybe...

yep I try ... figured I get everyone off the gearbox bandwagon .. LOL

ROFLMAO .. nice to see things aint changed ... you DA's didn't think I thought this post wouldn't cause a stir ??? it is a no win question .. just like always .. personal preference .. but he wanted some kind of an answer .. and both sabers and razors take less blades for the same HP compared to a w...

Razors and sabers are hollow .. warps are solid .. so warps might survive a light strike better .. maybe Razors and saber take more power per blade so you probably won't run 5 of them as for which is better .. my vote goes to the razors .. but just as many will go for each of the other blades .. no ...

Stinger and precision both have airworthy boxes that are FAA certified .. although it is a different company that gets them certified they build them ... many of the older planes have been permanently grounded because the engines they were certified with are done ... several companies have gotten FA...

if it is a rotator .. they sell it at panther / classic airboats I believe it is green

Whirlwind is "simply the best" like their ads say ...

70 percent efficiency would be great on an airboat .. probably more like 40 to 50 .. tops .. efficiency is expressed as how far the prop moves forward with each revolution .. in the real world .. lots of things to affect it on an airboat configuration .. cage .. seats .. uncowled engine .. transom ....

maybe try this ... Pitch is the tangent of the blade angle times the diameter where you measure it times pi. Theoretically it doesn't matter where you measure it but normally you measure it at 80 percent of the overall dia of the prop yes I found this in a reference .. no I don't use it ... and mayb...
