Re: Tilt motor
hot wire the motor. if it doesn't run right then it probably has rust inside. if it does run right then it is a connection or switch.
if rust -
take it completely apart including drilling out the two screws that hold in field windings. bead blast the metal frame and winding shoes. dip in ospho, prime, and paint.
remove old tape and wash windings in tsp or water based parts wash. allow to dry and retape using self-sealing cloth electrical tape. if you can cut new fishpaper great. if not carefull wash and dry old and the re-use.
polish armature shaft. if it shows pitting around upper or lower bearing then buy one of the shaft shims. They are an ultra-thin sheath of stainless that goes over existing shaft. I suspect grainer will have them. or abandon motor and buy a new one. or buy a new armature. or build a noisy motor that won't last as long.
if you had rust then get a new brush cap. they cost about $35 form marine power services. they come with brushes and springs. They come with washers too, but the washers are plain steel and prone to rust.
replace the 011 oring in the top af oil reservoir
replace the wire with #12 sjeoo electrical cable and the fitting with an appleton cord grip.
get a pair of 10-32 x 4.5" SS pan head screws, a pair of #10 bonded aluminum sealing washers, and a pair of gaskets. The Gasket MUST be the right thickness or your motor will not work properly. If you cut your own then use 1/32" neoprene and cork blend rated for both oil and ozone exposure,
and your motor should run like new when you finish
