With the numbers checked a second time, I would say you are over-pitched by about 2 inches....
If you can find a used prop that will fit, I would say find a Raker propeller in an 18 pitch. My guess is your hub is a little bit bigger than mine...if it was the same, I'd let you try mine...I have a 13-1/2 x 18 on my 90 and it does really well. I am thinking, though with your motor you would need the larger hub and a 14 x 18.
dropping in pitch by the 2 inches should give you about 400 or so RPM's, and then if you chose to raise the motor one hole, you would be right about there...
