This was my first year of winterizing and after reading thru the shop manuals and several posts here (thanks Lou C, your answers on the replies were helpfull) I did the full drain and refill manually with -100 AF. Local marina wanted $400 to just winterize and fog engine. I was tempted to suck it up as some due but my boat takes forever to warm up enough on the muffs to open the tstat. It was a pain to do, but I did get nearly 4 gallons of AF into the engine. Filled the block thru the big hose from the tstat to engine water pump, took 2 gallons, then filled both manifolds and the hose from the raw water pump thru the power steering cooler which took another gallon or so. I think I will go back and make sure that block is full to the tstat housing as I quit filling the big hose when it got to where it was just full enough to put on the tstat housing. Also changed the outdrive oil, engine oil, and fuel filter/water sep.
If your engine takes a long time to warm up on the water hose (like more than 15-20 min) I bet its not closing all the way, probably because of a little piece of rust keeping it from closing. You can try this trick when you run the boat in the water next year:
Get a small hammer and take with you on the boat. Run the boat up on plane long enough so that the engine temp is at least 160-165. Slow down and bring it to idle, before it starts to cool off take the hammer and tap lightly around the thermostat housing. This can loosen rust flakes and allow the stat to close. I have had this problem over and over here in salt. Even replaced stats only to have it again. Tested them and found that the stat itself was OK but if a big enough chunk of rust gets in there it has a hard time being flushed out.
I will more then likely just replace the Tstat next year along with a few hoses as I think alot of these items are original from 1993. The boat only had 87 hours put on it in the last 11 years after the first engnie was replaced due to a winterizing issue, and we put 50 on it this year. Needless to say that it has had some minor issues to work thru from not being ran all that much. According to my temp gage the temp will never go over 150.
