1648 all welded grizzly by tracker with a stock 2011 GTR
With me (205lbs) the wife and dog(200lbs) and 6 gallons of gas in deep water it ran steady 28mph.
Not sure if there is any adjustments that I can make or not but overall I'm happy with the way it runs and handles. I had a 25 horse longtail on it that ran 21 or so with a new prop and light load so its alot faster and easier to handle. Any input on adjusting or tweaking would be helpful. It seams to run the same speed from 3450 rpms to 3700 then falls off after that. Idles in gear at 1000 or so and out of gear at about 1250.
