We bought our first sailboat last year, a 1972 O Day 22. Needless to say we’re having a blast with it but are in need of a new engine. I think we’re going to go with an 8hp Mercury with an alternator. We’re hooked on sailing and hope to transfer a sound engine to any future purchases, but mainly we want a safe and sound engine so we won’t have to do any worrying while trying to get out or back to the dock.What I need to know is what shaft length I should buy. The outboard that was on this would hit the tiller if it was turned towards it and that just doesn’t seem right. Any input on this is greatly appreciated, whether the engine we’re choosing may be wrong or what I might need to do to support the added weight of the new engine etc.
