Hi new here... and I'm going to put power in a boat that's been without a motor for awhile. It had a Volvo so I'd like to keep it that way so as not to redo the transom. The boat is a 23 ft medium Vee, Cuddy. Long and lean. There is a lot of Volvo 4 cylinder motors out there for sale .. but I'm concerned that would not be enough. those are mostly 115 - 120 HP. I would like fuel ecomomy but it's got to move the boat too. and not work too hard . Any advice here would be great... Thanks
