All good advice so far. I also unhook the speedo tubes at the speedo and blow all the water out of them, loosen all the belts and remove the impeller. When I put the impeller in in the spring (whether it be a new one or the old one) I smear it with grease all over before I put it back in the housing.
My method of filling with antifreeze is similar to John's I think, but a little different.
1. Drain the water and fill with proper mixture of biodegradeable antifreeze.
2. unhook the hose at the top (upstream) of the tranny cooler (impeller suction)
3. Put a 5 gallon bucket on the fender of the trailer, run a rubber hose (1") from the bottom of the bucket to the tranny cooler. I cut "notches" out of the suction side of that hose so it's impossible for it to suck itself to the bottom of the bucket, and I also drilled holes at the top of the bucket to zip-tie the hose to the bucket.
4. Fill the bucket with proper mixture of AF and start 'er up. When it's close to empty, fog the motor and kill it before the AF runs out.
I can't believe it's that time of year again...
