Bushwacker-
Thanks for the measurements!
I am assuming my pivot point is correct for the Yamaha. It is sitting under 2 tarps waiting for snow...
I plan on on recreating the cap contour atop the transom, so that's what is shown in the model I have. Now I have to find the Yamaha manual and make sure I didn't goof the pivot point. I was lazy and pivoted it about the top of the bracket edge, but it is probably 1 to 1.5" above and forward of that point. With the 20" shaft, I will need the motor low on the bracket, I think. If I could only find a 25" Yamaha F100, it you be easier.
I do have a CAD model of the 130 from the internet. It seems to be the real deal. Maybe I can drop it in and compare. But no E-Tec for me. My F100 was $1000, and that's my kind of budget. Unless I find a 115 Etec for $1000
