Wish someone with a connection to Mercury could get their hands on the old "Boathouse Bulletins" from Lake X where they tested boat & motor combinations. The 1983 Mercury info for the Wellcraft V20 said 46 mph with their 150 V6 and a 19P prop, 20 gallons fuel, no gear and 2 persons onboard. I tried a 19P prop and went to 17P because real world is 72 gallons of fuel, ice chests and tackle. Mine did about 42 mph real world with a good load and 150 hp.

That's good speed - I'm getting just about 40.0 mph with 150 Johnson and 1/2 tank - 30 gallons on my V21. That was on the ocean, not flat so might get a bit more. With 150hp generally 38-42 mph seems the WOT speed.
