I know about the Seagull, but I've never seen one . I use my trusty, old Evinrude 4 HP twin cylinder. I believe Ole Evinrude invented the outboard motor, because when his girlfriend wanted some ice cream, he rowed to shore to get some, then rowed back to the island where his girl was. Unfortunately the ice cream melted, due to his slow progress with the oars.
The idea then hit him....make a internal combustion motor that would propel a boat. It would be faster than rowing and in a similar situation, the ice cream would probably not melt as much. I believe there is an old adage that says invention is 90 % perspiration and 10 % inspiration. I don't know if it applies here.
