Did I miss anything? Winterization checklist

[Fman]

Finished my winterization today after picking up the boat from the dealer, they just replaced the dripless shaft seal. Wanted to make sure I did not miss anything for the winterization.

Drain block (knock sensors, impeller inlet tube)
Drain heater (blew out with air hose)
Added fuel stabilizer (started this in September)
Changed engine oil/filter
Changed trans. fluid
Blew out ballast lines
Shop vac engine area/front locker area for any water
Detailed boat inside/out
Float chargers on batteries
Removed ballast bags
Cleaned air filter

For Spring: New impeller/fuel filter

Did I miss anything?

Thanks....:)

Have no idea where the trans cooler drain is, anyone?

Port side of motor below manifold, can't miss it, water hose going in and out.

remove both hoses from impeller....will take care of trans cooler and impeller housing

remove hoses from either side of vdrive.....blow or suck out any water

remove j tube off circulating pump.....there is water in here

disconnect exhaust manifold quick connect to drain manifold
