Well I bent my first prop today and decrease the pitch by 2mm on a new 15/20R Solas. Looks pretty good to me. I put the stainless wear ring in the pump and that prop fits so damn good I couldn't believe it. You can't see daylight though it and when you spin it it does not touch a thing.
Now I need to pull the supercharger and put the new ceramic bearings in and metal washers then my valve train upgrade. I should see some speed this year over the 14/19R last season.
