I picked up a used 18' Bayrunner (aluminum boat) from a kind lady that
her husband owned. He passed away. He placed a 15 hp outboard and
from the size of the boat it seems a bit small.

His son told me that with him and his dad they can cruise at 15-20 mph
and cut through wind with no problem so his dad never thought about
placing a larger motor.

If I'm in choppy water (1'-2') would this motor be large enough for me
and a friend to ride in? It can get windy where I'm at. I'm not
looking for a speed boat but I don't want to be underpowered for safety
reasons.

Any experience would be appreciated.
