Re: Looking at buying a 93 90hp, what should I look for?
Good visual inspection looking for broken or missing parts, frayed wiring, etc. Don't just check the lower unit oil, change it if you like what you see. Insist on a compression test while you watch. See if the oil injection system is intact and functioning. If not you'll need to pre-mix and then be sure to find out why the system was disabled. Ground the tan wire from the temp sender to see if the overheat horn is working. If everything checks out, insist on an on-water test (if its still on a boat) or a tank test.
