“I have a 2000 356 Cuddy and re-powered last year with twin 300 V’rods. I am extremely pleased with the motors, made a huge difference in overall performance, cruise 30+ knots 1.3-1.4 mpg (bottom paint). It made a totally new boat to me with the repower. I would check with Joe Brenna to see if the 300 Yamaha’s will fit, meaning being able to trim them all the way out of the water and not hit the back of the transom before you purchase them. The transoms have changed somewhat over the years due to the taller motors.”
