How do you properly winterize a 1988 Cafe Racers head? Details would be greatly appreciated.

i started by pumping out the holding tank and then used a 5 gallon container with a hose and gravity fed the toilet by shoving the hose into the inlet under the boat. i flushed until i used about 2.5 gallons of the pink stuff..

Thanks for the response, any other takers?

I usually disconnect the hose from the water intake. Use a long skinny funnel & clamp it onto the line. Feed the pink stuff while operating both switches. Never had any problem but do as Sean said to pump out the holding tank. Some pink stuff in there would'nt hurt.

You can buy a set-up for bottom pick-up at west marine or boat US for $20. But sean and cig1988 are both heading you in the right direction.
