I'd like to flush my late 80's Merc 9.9, but there's really no way to do it while it's mounted on the boat-if I tip it out of the water to hook up the hose, I can't get to the starter cord.
Last winter I had the boat on the hard, so brought the motor home to do some service, and left it in the garage with the intent to run it every couple of weeks-but snow on the ground and the hose coiled up in the garage instead of on the spigot made that inconvenient, so it went a month or more without getting run, and then I had to dissassemble and clean the carbeurator to get it going again.
This winter it's been on the boat, run every 2-3 weeks, and so far doing fine.
