about 6 years ago, a brother gave me an mini airboat hull, with a old hirth 460 motor( that was missing some important parts)
for what ever reason in all the searches on the web, i never came across this site untill last fall, man talk about lots of answers & information that is on these pages,
anyway, this project has been mainly just a dream, and last fall i was ready to get rid of everything, then i came across an old Cuyuna motor 460F-45 with the gearbox and prop. for a good price, picked it up, tore it down and got it running. then i came across the Mini Airboat page here.
then back in december i came across a 4a084 bare motor for real good deal, the seller had 5 airboats in Wassilla, and not enough time to acomplish all the dreams.
I have been dealing with 2 stroke motors for the last 25 years with Snowmachines, and still am trying to figure out which motor to use on this hull
both put out about 45 ponies, for fuel consumption, the Cuyuna will burn over 2 gallons an hour. but only weighs 70 lbs. with the motor, gear drive, and prop.
and the 4A084 it has been discussed quite regular.
as always i thought the aluminum hull was a lot bigger than it was, at the moment it is leaning against the shed, buried in about a foot of ice, and 4 feet of snow on top. been cold and rainy this winter, so it will be a little before i get at it. but it is 11 X 4 ft, with 16" sides. looks kind of tippy for the heaver motor.
oh the things we collect, and the fun we have with the choices we make.
at the moment i may build a motor frame for both engines and see what happens.
a couple of questions on the mounting locations for the 4a084 motor, at the moment it looks like a direct drive, but i would like to build the frame so that down the road i could change over to that fancy Circle S Redrive, where would i find a template for the 3 motor mounting holes
been looking at Corky's build on page 11, if he would be willing to give out the magic numbers off that template that would be awsome.
enough talking about me, maybe I hope to be able to contribute a few small things once in while, to make up for all the information that i have learned the last couple of months.
have a great day , we have 4 feet of fresh powder on the mountain, it is hard to get to serious when there is sunshine and fresh powder
