How fast does a mirrocraft striker 1567 go with a 25hp four strroke
The biggest disservice that you can do to yourself or your new boat is to put an undersized motor on it. Generally speaking, you don't want your motor to be less that 80% of the rated maximum horsepower. Anything less than that and the boat will not handle right and you won't be happy.
How many friends have you heard over the years wishing they would have gone bigger on their motor. conversely, you never hear anybody grousing that they wish they would have went smaller on their motor.
Horsepower is your friend. I wouldn't look at putting your motor on a new boat unless the maximum rated HP is in the 30 to 35 neighborhood. truly think you'll be happier in the end.
