An engine with lots of low end torgue is more suitable for an amphib , not a higher reving hp motor. Even with lots of gears you,d still need to shift all of the time in the places you'd take an amphib.

The only thing to remember is an argo trany is just like a Wrangler meaning they are built more for crowling then speed. If you are going for speed why not pull the engine and the tranny out of the bike and try going that rout

Member Duke had a motorcycle engine in his Gyp Sea. It was a honda atc 200, think it was a 200s.

Personally, I would never go that route with the transmission anyways. I just think you would spend to much time shifting it all the time. Foot shift or hand shift, plus clutch and gas, plus stick control would just be a pain. Foot controls are some what a pain to begin with because of bouncing around and loosing your foot position on the pedals. Being able to move around in the seat or stand, etc... and control it with just the sticks is sometimes very helpful when your on a hill, in the water for balance or stuck trying to positon for more traction in the right spot. If you have to have your feet planted in a possition to drive it, it would make some situations really hard to get out of I would think. CVT setup works real good in these machines. I would see if there is a way to eliminate or gut the transmission out and put a CVT drive clutch on the crank some how.

snowmobile engine is the way to go for reliability and performance

Someone had a Honda CB 600 engine that they put in a Ramco Retriever too.....they might have had it on the site at one time. I remember seeing it on ebay a time or two as well. As Larry said, I wouldn't go that route either. Just stick to a snowmobile engine, or V-twin 4 stroke. Both have their advantages, and both will make for a good power plant for your AATV.
