SHOULD do- I had a 3hp seagull as the auxiliary on this 5m hardboat:-
which weighed nearly 750kg with all the gear in the cabin and it pushed it along well enough to get me out of trouble. 4hp should almost be overkill- I had a 4hp auxiliary on a 14' dory with a cabin and it made nearly 4 knots. They aren't the most slippery shape at displacement speeds either.
At least with 2hp it'll maintain steerage way-and if it takes 3 hours to get 3 miles to shore then at least I'm ashore...and SR4's aren't exactly heavy.
I'll try both and let you know.
