1970 Weimans Cyclone for sale. I built this boat over thre last few years and we have decided to get into other hobbies. It is a very powerful boat and a lot of fun to drive. The paint is about 3 years old, it has some marks from usage but overall in very good condition. The interior is in decent condition again some markings from usage. The boat is a 3/4 Stringer boat (common for weiman/rogers boats).

The current setup and tune for the engine is about 11 PSI of boost and very conservative timing. It spins a BC impeller about 6500 RPM and has a lot left in it. This is very conservative and can be turned up quite a bit. This tune puts it around 700 hp. I have taken it out twice with this combo and it has ran great. At this boost and timing thats in it i am comfortable running it on 91 octane. But would recommend better fuel if turning it up any higher.

If you have any questions please reach out to me. Asking price is 15,000 OBO. Willing to lake test for serious buyers on their dime. Will deduct fuel and launch fees from the purchase price if purchased.
