I had the 18" chopper and the 12X20 prop mentioned above with a 70 Nissan. A 23 SRX took it to 57.6 on my GPS. All 3 hit the rev limiter. I miss that boat but time constraints make it pointless to replace it. When would I use a 3rd boat.
Was the nissan a twin cylinder? They had a high gear ratio, so the props would be to small a pitch. I only know of two 12 x 20 props in Ontario. Brian Sherriff had one and I still have my prop. Bet you got Brian's. That prop on a 49 Mercury with a 2 to 1 foot is very nice on a VooDoo.
