Most of SA boat ramps have Boat/Motor washing facilities included in your $10 to $15 launching fee, looking at launching in a small country ramp, no fee, no water available and I will not be towing our 1/2 cab home for a wash down.
Thinking of a 20Lt container of fresh water on the rear of our boat with a tube to the earmuffs and run the motor until the container is nearly empty...
or not bother about a motor clean out for the 3 or 4 dips in sea water until I get home in a weeks time.
Comments appreciated.
