Center console? MAXIMUM RATED POWER!
Not underpowered, depending. Especially if the price is RIGHT. The 20 grady walkarounds (W/A's are very bow heavy) are sold out the door with 150's, as are every other 21 foot stock package out there.
What are you gonna do to it and how are you going to load it? Likely inshore a drfit here and a drift there, drop the hook a half mile saway over there, etc. You can even waterski with that package and a hydrofoil will have you pulling 2 skiiers out of the water. Been there. 99% of posters will tell you that little boat is way underpowered and you can't have too much power, in which case forget everything here and hang a 250 on it, or whatever the transom rated MAXIMUM is, in which case I would have 3 motors
on my present boat (the max!). I have known some who had a 200 on a 21 W/A and felt it was too much. A 200 will burn 1 gph less at cruise than a 150 but that is a bow heavy W/A, a center console who knows, much lighter, more weight aft. See ya at the gas pumps.
Have fun with the new boat!
