Re: 1959 Evinrude 5.5 Golden Jubilee

snagger, how old is the impeller? If the motor is in super condition, the impeller is probably very old and is sure to fail. Good practice and common sense says replace an old one before you burn up the motor, not after when it is too late. Unless you know for sure that it has been replaced within the last couple of years.

The oil question war will never end. Original spec was 1 qt to a 4 gallon tank (16:1). Under no circumstances leaner than 24:1.
