I'm looking to buy a used Outrage.I'm trying to decide between a 19 and a 21.I've seen 19s advertized with everything from a 115 to a 225,and the 21s from 140 to 250.I plan to use the boat for fishing,but will probably pull the children around skiing/wakeboarding.What should I consider to be enough horsepower for each model?Thanks

cottonman,
I would get as close to the maximum hp listed on the capacity plate as possible.

You might want to look at the reference section of this website to refine your search. There are several styles of 19 and 21' Outrages (depending on the year), and they weigh different amounts and have different engine requirements. Also, you need to state if the initial cost of the engine and fuel economy are important considerations, or if hole shot and top-end speed are more important? Will you be purchasing a new engine? Are you concerned about resale value? Interested in twin engines? Are you leaning toward a 2-stroke or a 4-stroke? Lots of people here would like to share their knowledge and experience but you need to provide more information.

OK,I'm looking at a '96 or later on the 19,and '99 or later on the 21.I'll be buying the boat used with whatever outboard it has on it.Allmost none of these boats have 4strokes.which I would prefer because of noise,but apparently most of the boats sold during the late '90s and 2000-2001 were sold with 2strokes,and they are not old enough to be repowered with 4 strokes.I'm more interested with out of the hole than top speed.It seems to me that a 150 might be light for a 21 outrage,but maybe not.Thats the kind of advice I need.

I agree with knothead-maximum rated HP is the best rule of thumb.
From there, all it takes is a propeller adjustment to improve hole shot or top speed, or mileage, etc.

You will observer that in the post-classic Boston Whaler boat era there is a much smaller range of horsepower between minimum and maximum for most hulls. I think this is due to the general tendency for the weight of the hull to be relatively heavier than in the previous designs of Boston Whaler boats. Because of this, the recommendation to power the hull with the maximum rated horsepower is even more strongly given than in the past.

Do not imediately assume that a smaller engine will get better fuel mileage. A small motor at the lower end of the power rating may be working it guts out at high RPM and consume more fuel than a bigger motor that can push the same load at the same speed at a relatively low RPM. Not to mention less wear and tear on the bigger motor.

As they say in Texas, bigger is better.
Like above mentioned, big motors have more torque, work less if you allow them, and last along time.
Max out, work less!
