I was curious if folks disconnect fuel line and gear linkage at motor when travelling. I ask because of the stress on cables when motor is up and tilted seems a bit more than if motor is down.
I run the motor up about 1/3 of the way (PTT) to avoid hitting anything with the skeg, and drive off. The weight of the motor and the hydraulics keep the motor from bouncing around. I don't disconnect anything.
It all boils down to the question of how much road clearance you have. If there is danger of dragging the skeg, partially tilt it. Use a transom saver to support it.
What's this about stress on the cables? There shouldn't be stress on the cables if the boat is properly designed and the motor properly installed. OK, so that isn't always the case.
I generally disconnect the fuel lines and run my carbs dry for two reasons. The old gas doesn't sit in there for more than a few days and it won't leak out into my splashwell when the motor is tilted.
The motor is tilted up, (roughly 45 degrees) and sits on the trailer bracket. Cables and control lines are flexiable and lay coiled on the deck. Can't disconnect fuel line, it's routed directly to the fuel pump.
