My cat is powered by a 1999 Yamaha 50 HP four stroke. It was used to
motor from CT to FL in 2002 and as an auxiliary on the way back. The following fall it was used on a trip down to
Annapolis, then the
boat was hauled nearby for some
repairs and
maintenance. The main tank is 65 gallons and the gas was found to be deteriorated, so the
engine was run off a small day tank. The carbs had to be rebuilt due to bad gas stalling the
engine. Over the next few years the engine would fail once or twice a year. After researching the ethanol
fuel problem, the
advice was to not mix ethanol gas with non-ethanol gas, that the mixture would gel. Also the ethanol problems would include
corrosion of the alloy carb
parts and clogging of the jets with
corrosion byproducts. Now
cleaning and rebuilding the 4 carbs is a quick job due to a lot of practice.
Parts are not expensive. The
motor stalled last week with new gas in the little tank. Right from the
pump. I'm glad I was just out to get
fuel for the
boat and not the car. After reading the posts here I am going to add and inline filter to my fuel line.
