Outboard Changes

[AcezHi]

Bought a 6HP Suzuki 20" shaft.
Putting on the 2020 Aurora 850 Huntmaster.
I saw a couple different pages on the same motor mount.
One stated 9.9 max and the newer ones state 6HP Max.
Now if the mount arrives I will post the results.

Has anyone ever considered tapping into the fuel tank for an outboard instead of carrying an extra tank.
Just a piece of hose and a connector would weigh a lot less than an extra 6 gallon tank, not to mention the space it takes up.
The newer 4 stroke motors run on unmixed gas.
Just a thought to save weight.

I have seen a few guys tap into the main tank with great success.
Definitely saves some weight and smell if the tank leaks a bit.

I am curious to see an aurora in the water. The major thing that I am sure I would hate (but would likely adjust to) is the steering system on the left hand side. The outboard bracket is on the right side, so you naturally sit on the left side of the machine.
When in the water, my wife typically runs the wheels to reduce any drag, so we would both be sitting on the left hand side. It wouldn't be the end of the world in the water as we could use a throttle lock, but once we are approaching shore and using wheels only it could be a pain in the butt.


Let us know your GPS speed of the 6hp when you try it out!

That is great I think that would be easier than carrying a external tank.
It floated pretty well. I was actually surprised how stable it was.
I am still waiting on the 617-10 mount. The 6HP 20" shaft is in the garage ready to go.
First time in water yesterday.

I finally got the outboard mount.
Tried with the Suzuki 6HP 20" shaft.
Goes pretty well. Still in a break in period so can't exceed 1/2 throttle. At half throttle I would say about twice as fast as tire propulsion.
I did notice as I get to half throttle with the 20" shaft I seem to be getting cavitation.
Maybe the 25" shaft would have been better, but went by the recommendation with the mount.
I am going to add the extra gas tank to add some weight to the rear to try to get the motor deeper in the water.
I am also going to trim an inch or so off the mount as well in hopes of eliminating the cavitation of the prop.

glad to hear it.

If you have a GPS handy, or can download the app to your phone you can check your exact speed difference. I would be interested in hearing what you are getting out of it.

I was questining my Android gps as I got 1mph on water with tires and 2mph with 3MPH for a moment on outboard at 1/2 throttle.
The wife and I are under 300lbs combined.
Have not had the chance to get it back out there yet for more testing.

Put another 4 hours on the outboard putting in the river and across the lake.
After a break in to the point I can use more than 3/4 throttle I have decided that just above idle speed in gear is just as effective as 3/4 throttle.
It floats higher and does just about the same speed.
I definitely need to check the bilge pump as it has never spit anything, but the drain plugs let out a fair amount of water when pulled.
