mudcatwilly Posted August 8, 2006 Posted August 8, 2006 OK, so I just bought my first boat. A 1975, 16 foot Lund trifoil with a 1990 85hp Suzuki 2 stroke outboard. I'll be honest. I know how to operate a boat, but I don't know the first thing about outboard motors. I'm pretty handy and can figure stuff out pretty quickly, but I don't have a clue on how to properly maintain this motor. It runs well now and I want to keep it that way. I couldn't find much on the net on proper 2 stroke maintanence. My plan is to take it in once a year for a diagnostic checkup, but in between that time, what are some things that you guys do to keep your 2 strokes running strong? Any help would be appreciated since I know nothing now. If it helps, the carbs were recently rebuilt and it was given a new aluminum head. I have to mix fuel at 50:1 in the tank. By the way, what is the best 2 stroke oil to use? Thanks Quote
Super User Way2slow Posted August 8, 2006 Super User Posted August 8, 2006 I'm partial to the Penzoil synthetic for everything but DFI motors. For those I stronly recommend using the manufactors recommended brand. Synthetics don't carbon a motor up as bad as fosil oils. A good maintenance program would be to winterize the boat and motor every fall when you get ready to park it for the winter. This also involves changing the LU oil, lubing, putting fuel stabalizer in the tank and purging the fuel system and carbs, making a good visual check and installing a new set of spark plugs, cleaning battery and terminals, checking/cleaning and packing trailer bearings, making sure all pumps and drains are purged with air so no water can freeze in them and keeping a good battery maintainer on the battery/batteries while sitting, or charinging the batteries every month and checking the water. Decarb the motor every 50 hours and run some type of carbon guard like SeaFoam or some other between the decarbs. Replace the water pump impeller every two - three years. Quote
