2 stroke / 4 stroke advice
"Garland Gray II" wrote in
: 4 strokes are great for a lot of reasons, but if fuel quality is questionable, they can be more trouble than 2 strokes. I've had fuel problems with a 9.9 Yamaha 4 stroke, and an ob mechanic said water or trash caused more problems w/4 strokes because of the smaller jets. Also, if you look back at the "good ol' days", remember when "winterizing" the old 2-stroker meant hauling it up the dock and putting it in the garage until spring? When you took it out in spring, just as greasy as you put it away, it wasn't all rusted up coated with oil like it always was. You poured PREMIX gas into it and drove away. We have a Nissan 8hp 4-stroker for a Foldabote 12 on Lionheart. The carb has been apart a few times, now, because it had raw gas in it that evaporated into solid shellac, plugging the jets so it wouldn't start. This wasn't an issue with the old PREMIX 2-stroker because the oil in the gas DIDN'T evaporate and kept the stuff left in the carbs in LIQUID form the new gas would simply remix with and away we went. My little Yamaha 3 with the gas tank on top is like that, too. It was stored for years and the premix still kept it from solidifying to shellac. Changing the oil on a marina dock or sailboat STILL sucks, too.... As to the 100:1 oilers...no thanks. 50:1 is too thin to oil crankcase bearings, no matter now much greenies and the EPA hype it. When I sold my 1997 Mercury Sport Jet 175hp-powered Sea Rayder, all 6 cylinders were within 5 pounds of their original compression and ran great on 40:1 PREMIX, the troublesome Mercury plastic oil injection pump and system having been removed as soon as I found out about the 2nd recall blowing powerheads with NO LUBRICATION. That boat's still running and the engine had well over 1000 hours on it....on PREMIX. Larry -- According to EPA, all lakes that have had 2-stroke engines running in them for the last 100 years must be 6" deep in motor oil. See it? Oil floats, ya know! |
