I'd agree with Shep on this one. Here is the nice thing with yamaha motors (at least from the ones I have seen and worked on). The shaft on those engines should turn rather than engage by going up or down like the OMC products did. what this means for you is an even easier job of pulling the lower unit if you do it yourself as the shift linkage will be a splined shaft.
So...to remove the lower unit, there will probably be 6 bolts: two on each side of the lower unit that you can readily see, one under the back trim tab and one on the top back portion of the lower unit. There is probably a black plastic cap over it.
Once you remove those bolts, the lower unit should just slide right down and out....one of the easiest removals out there for a lower unit.
If you do this, have the dealer replace the water pump impeller as well, given it has not been done in a while. Preventative maintenance there, guaranteeing your cooling system is ready for spring.
By chance do you live in a cold climate? If you had some water come out, it could very well be possible that the lower unit gearing is frozen together, thus not allowing you to turn the prop. That is why you can only engage it one direction. If you could spin the prop, you would find you could engage it both ways by spinning the prop in gear one way, then going to the reverse gear.
Oh...and just a quick question midge...where are you located? If you are close to the twin cities, I'd give you a hand on it..
