Re: a few questions about 1975 Evinrude 70hp?
what do you mean by the 40hp being a 50 compared to the 70? I am looking to replace the old 1965 Johnson with a newer better running motor. the Johnson has a carb issue and I am getting water in the lower unit. I like that the 40 is newer and lighter than the 70, but the 70 has power t/t, not sure about the 40. Also, I am worried about getting the 40, then wishing I would have gone bigger for a little more speed. the boat weighs about 500 pounds, how many mph difference do you think I would see between the 40 and 70 with 2 people in the boat (sometimes 4)? Thanks for answering my many questions.
1: HP standards have changed. The japs were sending outboards in the late 70's with power measured at the prop shaft - not at the crankshaft. They were running rings around the US motors. The 40 is of the era of the more conservative HP rating.
2: Makes sense to cut losses with your older motor.
3: Compared to your 60 (a tank), both 40 and 70 are light - weight of the motor is a non-issue.
4: T&T is nice, but it hard to find a reliable runner in that price point. Both are fairly easy to tilt , compared to your 60HP beast.
5: Speed. You didn't indicate what you are getting for speed and what the boat is used for. Everyone wants more power and top speed. ...that attitude changes fast when they break down.
