motor swap

Will a briggs or kohler opposed cylinder engine fit in a max 2 with little mods or will it be to long and hit trans

23hp vanguard fits right in only exhaust will give you trouble.

The 23 Briggs is a nice conversion for a Max2. If you install one you can route the exhaust out the rear of the hull. That also helps with motor/belt adjustment. The motor mounts on the stock set up can also be modified to allow you to slide the engine either forward or backwards for additional belt tension. I have not modified my Max 2 motor mounts yet but plan to do so in the near future. You can also lower the center of gravity (which is already good) by lowering the motor another 1.25" or so.

Larry,

The motor mount on the Max II might be too low to swap in an opposed Kohler or Briggs. I've not tried it, but I know that the motor mount is quite low as opposed to machines I've seen that run the Oppy's from the factory. I've seen Hustlers and MaxIVs use them, but their motor mounts are all up-high. If no one else chimes in that has tried it, consider yourself a pioneer, and see what becomes of it!

Larry, I did look into using a Briggs opposed before I went with a Kohler v-twin. I did have the Briggs set in to check clearance and I was surprised to see that it fit. I did not go any further, like checking belt lengths and so on, so I don't know any more other than it will fit in the location.

I thought you weren't supposed to try and adjust tension on those belts just buy a new one of the right size??

Even with the correct size, belt tension will often need to be adjusted.

Yes an opposed twin Briggs or Kohler will fit in a Max II, I believe they were called Kohler Magnum and Briggs I/C (industrial/commercial). 6x6World member Racerone3 put my 18HP Briggs I/C out of my Hustler BIGFOOT into his Max II.

here is my wife's old maxII with an 18hp opposed briggs.


this was originally a 2 stroke machine, so i had to build a mount for the engine. i can't seem to find any pics of the mount, but if i do i'll edit this post to include it

I'd love to see the mounts if you do a tear down or have to pull the engine. I'm not dead set on a swap yet but I just sold my two stroke so I can buy a 4 stroke, and opposed twins aren't out of the question especially since there seems to be an abundance of them cheap.

Sorry, but that machine was sold somewhere around 2011. That 18IC briggs was a stump puller! I used to use that machine to pull a trailer loaded to the gills with firewood and it never bogged down a bit

Sweet, il keep that in mind, at the moment I'm leaning towards a chonda since I saw some 18hp on sale.
