I have a Johnson Sailmaster 8hp. 1989 on a 7.3 meter S2. It has stood the test of time and is not loud. But, there have been times when facing a two to three knot current my speed over ground was near zero. A five hp would probably be too small for a 26 footer in any kind of sea or current regardless of prop size unless you are using it on a small lake.
