Last year my 6HP Yam allways seemed too deep, with the waterflow hitting the wishbone, and the mounting board.
This year I have raised the mount one bolt hole, but it still seems too low, as high as possible with out drilling new holes. I have the better spring loaded mount with the two "down" positions. I leave the motor in the higher position. (I can acutally run the motor in the UP position and it just starts to suck air & cavitate)
Does anyone have a method for determining where to mount the engine, say ..relative to the bottom of the transom?

I don't know the answer to your question. However I've got another to add to the mix: The port motor mount on our C22 is not perfectly verticle. It's tilted such that the shaft/propeller is slightly left of verticle. Is this normal? Maybe to compensate for being off the center line of the boat?

Hi, I also have a 6 ho Yammy (long shaft) and sometimes it seems a bit deep but if I raise it any, it will not back up so easily. One point is that to actually see how deep it is while you're running, you have to unbalance the boat by shifting your weight to the stern and getting further back in the cockpit.
As for Bilgeboy's question, I d say that this doesn't matter. having the prop a bit port of centerline will change the thrust a bit in a bad way and having it away from the transom may help in a good way. Are you satisfied with the way that the boat moves with the motor? That's the big question I'd think.
