Outboard mount C 26

				Hello all,  long time reader here, first time posting.
I have a 1978 C 26 we got her about a year a go.
over all it was in good shape, lots of barnys and outboard on last leg.
so as it goes off to the yamaha dealer I went to pick up a new 9.9 high thrust long shaft, mouted it up and quickly found that at 90 deg. down "tilt" the lower unit hit the rudder "the rudder was in the up position, water in canal can be 3' on low tides spots" . trim up till I clear and off on a quick test run I go. with trim set so high the prop wash was only 2 to 3 feet behind the boat an coming up out of the water.
Back at the dock I noticed " larger then before" cracks in the fiberglass OEM mount. And when the outboard was raised it hit the transom and lower unit was only about 1 1/2" out of the water.
So I am building a new mount, the angle on the back of the old mount is alot and lets the lower unit go almost under the boat when trimed all the way down not sure why this is ?
I think its around a 30 deg. angel. Less to me might be better ? the new mount will move the clamp of the outboard out to 12 1/2" insted of the OEM 5 1/2" from transom hope to clear rudder when trimed down "and rudder up" and transom when tilled up and out of the water.
Any input would be very helpfull ! not sure what effect this will have on the boats handling and performance if any.
Thanks Dave
