The boat was repowered with Mercrusier 8.1 High Output gassers rated at 425 HP and tuned for more low end torque. The engines currently have 480 hours on them. Anyone familiar with the powerplants and opinions? Boat is going to be strictly short distance pleasure use. Harbor cruising and weekend Catalina / local costal trips.

Thank you for your response. What props are you running? What kind of performance are you getting rpm/knts wise if I may ask....
I'm turning 18x21 three blade props. 3000 rpm I'm running about 19 knots, 3200 21 knots in fair seas. That is also on the original motors, with over 4400 hours now. I'm also on Lake Erie. They are really well-built boats. I'm surprised how well mine has held up.
