View Full Version : Merc Sportjet 90 Winterization question!

10-29-2002, 01:16 PM
It's wintertime (ugh!) and it's time to put this SeaRayder asleep.

I have the clymer manual, and it says to do the usual fog, etc. I have stabilized the gas, but my question is whether or not I have to actually add antifreeze to displace any water that may be still remaining in the block. the dealer is very backlogged, and since I purchased the boat from the dealer this year I only had the boat in the water 4 times for a total of 10 hours.

Most outboards I have had never had a bit of trouble if stored for 6 months without doing anything....for 20 years!

Any help is appreciated!
