RE: Twin to Single conversion- Oh My!

Just repower it w engines half the size of the originals. Many of the engines in the 55 to 65 hp range are naturally aspirated and the total power would be the same. In that size range (like Tony says) most buyers are going to want twins. The vastly better maneuverability afforded by twins is much more important w a boat of that size. In that size range I'd recommend twin screw and thrusters at both ends. This plan would provide the greatest in maneuverability and economy. There was a GB 36 that has had it's 2 120 hp Lehmans removed and 2 55hp Yanmars installed. The boat (I think) produced was considerably more economical to run and more seaworthy as well.
