Removing Oil By Draining
Refer to Preparing The Sail-Drive on page
45.
Oil draining is possible when the vessel is
out of the water but will take a greater
amount of time.
1. After approximately 0.6 L (0.6 qt) has
been drained, remove the oil changing
plug. If you remove the plug before this,
oil may spill out because maximum oil
level is higher than the plug.
