Hello,
I have a 2004 20hp Honda and I'm preparing to perform the 200-hour maintenance myself. I'll do the job off the water, with my sailboat on jacks.
The owner's manual says you should change the crankcase oil when the engine is still warm. It will not be possible, since it will take a couple of hours for the boat to be hauled off the water. I have a flushing kit that allows you to attach a garden hose directly to the engine's head, close by the thermostat. Again, the manual says you should flush the engine by only turning the water on. Nothing about turning on the engine. What do you guys think about that? Can I turn the engine on, since the water pump will be "wet"? Or, instead, should I maybe drain all the cold oil I can and then "flush" the system with some 10oz of fresh oil?
Thank you!
