    battery charging issue has me stumped

    As you probably know, reversing battery wires for a split second will blow out the rectifier, as would disconnecting the battery while the engine is running. Don't give up on old Bill from Occam.

    Backup temperature gauge+sensor (digital)

    Maybe this, at the address Crosbyman suggests. The old-style OB gauges had a sensor and bracket for physical contact with the top of the powerhead (think this one would work that way too)...

    1982 Evinrude 90 hp
