Not meaning to hijack....
Some guys on the Little Red are running the Skiff with 25 hp converted jets like yours. This seems ideal since I have found some rocky ramps into prime musky water that involve winching the boat on dry land to the trailer. Boat seems to plane well, just not sure if its enough power for a 500 lb hull.
If I go with the 40/30 Yami, I get more power, but about 70-100 more pounds of weight, which limits the maneuvers I can do to drag the boat over ledges and dry land.
I get the boat first week of April, then the work begins.
I will have a chain hoist, so I can switch motors.
