Winterizing queries ?
I am about to winterize my Mercury 4-stroke 90hp engine.
Apart from using a stabilizer, is there anything else I should do to minimize the effects of long duration storage of my boat? It will be winterized next week and won't be in the water till next June-July...This means the gas will be sitting in the tank for some nine months. Since I don't use the boat enough to completely empty the large 100 litre tank each year, a bit of that gas is from the previous year. I read many posts recommending the use of higher octane gasolines. Is there any reason why the advantages of higher octane not apply to 4 strokes ? André |

André I'd drain as much out of the engine as possible and put the fuel in the car and get rid of it as I drive (in small doses if it's premixed with oil). Other than that, flush & antifreeze the cooling system, change the oils, plug up any place bugs and birds can get in and the rest of the standard list of winterizing chores. I like to take the impeller out, but it could be a PITA in your engine. 'Course, change it now or try to find all the pieces when you change it later is a continuing question.... -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |
