Thanks Chuck,
I have drawn the two engines in AutoCad and have to now add boat dimensions to
view the required adaption to widen the 11.5" to 16" keeping the same shaft
alignment. Lots of time to complete and I was hoping someone had done it
already. I had fun when I picked up the engine from the San Juan 34. The owner
told me to take anything I wanted from the fiberglass corpse laying in a field.
Not much was left and I didn't have much time. Now that I'm home I'm wishing I
had looked for more stuff. While its cold out I plan on doing good inspection
and testing on the M20 before I stick it in. Lots more to work out....exhaust,
prop size, fuel filter and return line, control cables, shut-off, on and on.....
Anybody ever use the boom to hoist an engine in? I've seen it done to remove
one but not sure how much the boat would lean when picking the 365 pounds m20
from the side.
thanks again for the comments Chuck.
Brian.
