I have a 1983 15hp Evinrude e15rcta. Very well maintained, sat for a number of years with the previous owner as a back up, which hardly got used. 100 on both cylinders, has good spark and we rebuilt the carb. We also installed new fuel lines, fuel connector, thermostat with seal and cover gasket. We gave under the flywheel a good inspection and when I get her to the lake, 32 pulls to start. One pull all day long after it warms up. All three times I’ve gone out after getting the motor, the same.
