A marine mechanic shouldn't have much trouble working on it, no special tools, but you do need to order the parts and I would try to get the service manual. Props were tough to come by, but I heard they make different shafts now and hubs. Good luck

I also have access to 2 MX-107 drives ( a Rt. & a Lt hand ) With 2 really nice Spinelli stainless props.
I also have A 19 spline 25 pitch Nibrel Lt. hand prop that I would sell.
If you are interested in any of this let me know.
