Hi, my 1988 60hp Evinrude model #E60TLCCR has an inoperable tilt n trim. The electric motor has a lot of dirt an rust on the connections under the cap, I removed the whole unit an have it on the bench. Are the magnets supposed to be affixed to the cover? They are loose, also the oil pump assembly has two locations for the drive coupling but only one drive coupling. Can I get a rebuild kit or do you have to replace motor as a unit? Thanks Neil74
