12/22 Impeller Results
I have been stuck on 67-68 mph (GPS) since day one. I have exhaust, intake kit, R&D grate and have removed the arrester. I did the following yesterday:
1. New Skat Track 12/22 that I bought on the site.
2. Removed the plate shims and added .060 washers in the front.
3. Added the inserts that fill the voids in the grate and hull.
The wind was blowing and the water had a one foot chop, so it was not perfect. The hole shot cavitation was gone and it was consistently at 70 mph. It will probably go a little better on smooth water.
In my opinion this hull/engine is on the limiter right out of the factory. Power alone is not going to get you better speed.
