I just ordered the new 90 sho so I know it’s going to be hard to get advice on this. My boat is a 16x52 double bottom homemade bateau about 800lbs. I have a micro jacker so I like to run 4 blade props. The x7 ss seams to be the way to go, 17 or 19 pitch? I recently got rid of a f70 on the same boat. I had fits trying to prop it, hopefully having almost twice the cc’s will alleviate the problem. Anyone with something similar I would appreciate the input.
