Re: New motor
Agreed....... Check for hp max.
If it's rated for a 25hp motor, I figure it will do about 28mph with one person and about 26.5mph with 2 stout men. If it's going 28mph, it's probably right on the edge of control and not all that safe. If it's rated for a 20hp motor, the 25 will be dangerous with just one person in it; really unsafe in any kind of wind.
I'll bet a 15-20hp motor would be ideal for it, unless it has a lot of weight in the boat like decks and such. If you can't find a hull ID plate, measure the width of the boat and report back.
