First, let me say I know extrememly little about outboard motors,except maybe a few very basic things. I just acquired a boat last summer for the first time in my life and the thought of owning one had never crossed my mind. This boat turns out to be a 1973 19 ft Starcraft. The old Bill Dance series, if that tells you anything. It runs a 73-74 115hp Evinrude. The tilt was shot and so was all the wiring. The wiring was there, just totally rotten. So I replaced all the wiring without any problems. Then I managed to locate an inboard hydraulic tilt unit and figured out how to by-pass the old tilt with this unit because I liked the idea that it wasn't exposed directly to the water. So far it's been a great little boat for the wife and I. Now friends tell me I should be replacing the water pump and vein and that this is supposed to be a simple operation that only takes a short time. I agree that it needs doing simply because the boat was neglected for so long and I know very little of its' history. My problem is that I don't see any visible bolt pattern on the outside of this engine that would appear to allow access to dropping the lower unit for this repair and I don't have the foggiest idea of how to go about it. I DO have most any tool imaginable from building car engines most of my life, so I'm not scared of the job. I'd just like some sort of reference on this particular motor and what to expect before I risk screwing something up.
