But 4 strokes have a big problem , expecially for someone who goes fishing and needs to remove the engine from the boat and travel with it sit on a side in the trunk .
Oil will pass through the piston rings blocking the engine.
And if happens to have the valves opens it will pour out .
Way better two strokes in this case .
Three years ago someone bring a Yamaha 8hp 4 strokes with this kind of problem.
Very true, but OP is looking at 60hp so doubt he's going to be transporting far unless its on the back of the boat

Cheers,
MM
