I have a Blazer Lauterbach with a wire drive and one with a flex shaft and they both seem to like the COCR Th1 and Th-1 -5. The one with the wire drive is seeing speeds pretty consistently between 60-63mph. The other one around 60 ish. These props seem to work on several different hull types so they’d be worth a try if you know someone that’ll let you borrow one for a minute.
