I am planning to install a subaru (170HP) in my C-120 on floats.I
realize that the offset of the engine should be 3 to 4 degrees but the
tilt I am not so sure of. The extra thrust should cause a reduction
from the original 85 HP application; I should think. Any suggestions
out there.

Try it first, then add spacers under the engine mount as needed. Nothing
beats real life corrections.
