Clancy 1010,
Look inside the railings for a maximum capacity U.S. Coast Guard sticker that will tell you the maximum load, people, ad motor size you can carry on it. If it takes a 70 horsepower then go for it and put it on if it is running good for you. For example, I own a 1991 model 202 Lowe's for Johnson Pontoon boat and I can only take a maximum of 75 horsepower on it so I have a 70 horsepower 1983 Johnson outboard on her. When I bought it last year it only had a 1991, 25 horsepower Johnson on her. Let us know, Bob
