Max is 150 or 175, can't remember which. I only fish the Great Lakes so speed is almost never a factor. Even on the calmest days I rarely run it over 25 mph. It'll do about 38 with a light load and flat lake but as I said I usually baby it. I've had a 25' Lyman a 23' penyan and this is my favorite. Easy to tow and easy on gas. It has a terrova ipilot and a 9.9 pro kicker. Very versatile boat and great on big water. I never had a big 2 stroke so I cannot compare.
