These flashed motors do not have the variable valve timing. With the stock 150's, I could get close to 50 mph on my Tom Cat 255. Cruising speed easily in the 35 knot range. Not sure where I would want anymore speed than that. One day, after a week at the Apalachola C Brat gathering, I raced my wife home--she was in her Lincoln Town Car, and I was in the C Dory Tom Cat 255. I won. I had only two very short "no wake zones" and could run in the lower to mid 40's. She had traffic all along the way, which kept her speed down. Distance traveled by both the boat and car was abut 200 miles.
