27 year old boat,given to me, so far only have the cost of title and registration, new battery, 10$ carb repair invested in it. I don't want to sink alot of money into repairing broken gears etc. in upper/lower unit, anyone give me some ideas cheapest way to get this fixed. I have some broken teeth in upper unit. I see the cost of rebuilt units are astronomical. And please don't anyone say I should just go and buy a new boat, if I had the money for it I would, plus the wife would nag for 10 years. so anyone out there help me? How do I go about finding some good parts real cheap?
