I own a 2023 R27 RSBT2 with twin Yamaha 300 DTS outboards. Boat came equipped with Yamaha Saltwater Series II HP 15 1/4 x 18 props. With a full tank of gas and 2 large adults, the boat will do 58mph at 6000-6100 MPH. Boat will slam you in your seat which I love. But curious what others a running and what speeds you are getting. I'm curious if going with the same props, but either going to a 15 1/4 x 19 or 15 x 20 would give me better top speed. Which one of the two would be best for my toon.
