I did not want to say that it is a Checkmate 283 Convincor. I thought I would hear that all checkmates do the "Checkmate hop" which is mostly 251/253's and not get any good suggestions.

never really heard of that at that speed, but sounds like the props are wrong...maybe has hydromotives which are a stern lifting prop vs bravo 1's which are bow lifting ??? would think prop/trim changes would take care of that..

My straight bottom boat porpoised when... 1. I ran the drives spinning in, 2. no hydraulic steering, 3. Hydrmotives. 3 blade Mirages changed the attitude the best. Also Spinelli's. I have a plethora of Props Spinelli's, Bravo1's, and Mirages if you need to try before you buy.

Thanks Rookie. I sent the owner a message regarding what props are on it and what direction they spin. His reply:
They are 26p labbed Mach 1s. Small pitch due to the 1.36 drives. They spin out.

The props are Mach props. I think they are called "Stern Drivers" A lot of Checkmates came with these, they were round ear props. I think Reggie bought the company and shut it down after a while.
