I had a few people ask me for numbers on the BlackJack with the Yamaha SHO - so here they are! The boat was accidentally shipped with the wrong prop, so Kyle at Lake Area Marine had the correct one overnighted for me and I got to check it out today. Another big thanks to Kyle for getting me set up right. Once the boat is on plane the speed runs about even with the RPMs, for instance at 3500 RPMs I was running 35 mph. It cruised very nicely at 4000 RPMs doing 40-41 mph. Top end was 63.8 mph on GPS. The boat leaps out of the hole shot. I didn't have to touch the trim tabs and the boat was solid as a rock at WOT....not squirrely whatsoever. I was extremely impressed. If you're in the market for a new 4 stroke I definitely recommend checking out the SHO. It is a beast. The speed data I collected was with 1 person in the boat, all my fishing gear, and a half tank of fuel.
