Almost 13 years ago I bought a 1991 115 HP Evinrude for my project boat. Seller gave me 3 months warranty, and the motor was delivered winterrized, at least so he said, and there was oil visible in the carbs. Motor had at that time been sitting 3 years, due to his health. My life changed, its been moved twice, and I have been rebuilding our home - etc etc. The last 5 years its been sitting outside, but under roof. I turn it by the flywheel a couple of times a year, and I have added thin oil to the bores thru sparkplug holes, a couple of times. It turns freely and smooth, with lots of compression, and gears are shiftable by fingers. Do you think its still ok, or should I find another motor, now that retirement is around the corner, and I am ready to take the procejt back on ?
