How should I transport my small outboard in a vehicle?

Two stroke motors can be set on either side but you want to make sure that when you carry or set it down the powerhead stays up higher than the lower unit so if there is any water in the exhaust it will not run back into the cylinder. Four stroke motors should also keep the powerhead higher but you want to check your owners manual for which side to lay the motor on. Yamaha recommends to lay the motor so the tiller handle side is down. This is to keep the oil from leaking out of the crankcase.
