Re: Nissan / Tohatsu 6h 4 stroke
I have the 8hp Tohasu on my Hunter 23.5 and it won't rev out either. However it will push my boat at 6 knots in smooth water at half throttle. Trying to open the throttle more doesn't do much. The engine is smooth and quiet being a 2 cyl. But even this larger engine is not producing all it's horsepower on my boat. The old Johnson 4 hp two stroke I had before would push it almost as well but used a lot more fuel and was working harder. The little Johnson works very well on my 16' Sunbird.
