I have a 951 DI motor that Tom rebuilt for me. Other than it taking a while to get, I have 0 complaints! It runs great, and has good compression. I have about 60 hours on it over the past year riding exclusively in the ocean. It always starts right up. If and when I need another rebuild I’ll be sending my motor to him again. I didn’t mind the extended turn around tile as it was the dead of winter for me. The turn around time was much longer than expected, but, it was also the begging of covid where everything just stopped. I’m happy I had him rebuild it, and he provides a warranty as well.
