I think he meant your crusing rpm stated in a previous post. You said you cruise at 2300 rpm faster thant most people you run with.

Thanks your right I miss understood him. My deck over runs a 2.68 Rotator and I cruise around 2,200RPM or 850RPM at the prop. On more reason why my boat is so quite.

Belt or gear drive is the only way to go. All you have to do is drive one and you will find out there is no comparison.

Belt Dirves

Postby Airboatcapt2 » Mon Oct 17, 2005 9:46 pm

I have customers running belt drives for over 15 years with no problems. (Some not even changing one belt).

"I'm a big fan of the belt drive"

Used hundreds upon hundreds of belt drives.

I have used a dozen gear drives and have had several problems.

Belt drives have their place their good reliable but they don't perform as well as a gearbox. But that’s my opinion I look at it this way if I want to tow or haul something I use my diesel truck if I want to joy ride and zip around corners I drive a Vete or Camaro. The Vete don’t haul very much and my truck don’t turn well so they’re both good at something but their not the same. The belt drive is a truck and the gearbox is the Vete.

You guy's are killing me. I do try to supply a motor for each budget, that’s why I came up with three different motors the rebuilt motor the high performance blue printed motor and now to cover the crate motor peddlers that were bashing me I sell an all new motor with much higher quality parts than the crate motors. Like I always preach, each application requires something different. Anyway if the next run is in Melbourne are you both attending? I look forward to ridding with you guy's

I have ran both set ups. Both have pros and cons. Direct drive takes my vote over all. I currently have a 500 caddy, 2:1 belt drive turning a three blade Powershift prop. Better performance, but tough on the engine. Stay with a direct drive and a two blade paddle prop and you won't have to worry about the anything. You won't have much snap, but top end will run with the aircraft engine boys. They won't like to hear that, but been there done that. One problem with the direct drive is running the ground or getting stuck. Been there done that too!! Have fun :D

I've run a DD Caddy for years using different hulls, and they have always performed extremely well. I just added a rotator to my new rig, and it definitely outperforms a DD application. My cruise rpm went from 1900 rpm using a three blade, 72 inch "Q", to 2100 rpm using a 79" Whirlwind 2.0. I have gained much more push, and it would be difficult to go back to a DD application.

gear reduction, so you do not have to worry about thrust bearing

I'm starting my build in two weeks. Alumitech said I'll have the hull next week. I was lucky enough to buy the last 500 that Glen built before he retired and sold Muscle Machine to Mark. Gotta put a plug for Mark "good dude and I'm sure he'll maintain the same quality that Glen's known for. Mark has been with Glen for years and I'm sure Glen will be hanging at the shop. Anyway, I bought a 2.09 OxBox for this build and the new Sensenich "J" for it. And man them components are "purdy"

Ducknutt, not to be nosey, but when did Glen retire and sell the shop to Mark? I am hoping just recently. Based on what I've read here and heard elsewhere, I've referred some folks to Muscle Machine and had been telling them to talk to Glen. Just curious how long I've had my other foot in my mouth. :oops: .. Good box choice, by the way. :thumbleft:

Deano - I went and bought my engine about 6 weeks ago and Glen was there but he had already sold the shop to Mark at that time. We joked about him being there and he told me he'll still come hang out as much as "mama" lets him. The lucky part for me was Glen had the last of his engines in the clean room and one of them was the 500 I bought. I've got Mark's cell if you need it, just PM me.

I don't have an airboat but I've been around them sense the 70's pre gear box or belt drive. I can tell you my friends went to gear box and other friend went to belt drive. the different is weather you get out of the boat and push or not. If I were to buy my self an airboat it defiantly have a box on the ass of the boat hands down. No more pushing LOL.
