Hi ric, apologies for not responding to your question. I guess I missed it first time around, but better late than not at all. I am running the SS Yamaha Reliance 17p SDS. Find it a good match for the boat. My WOT is 5700 rpm a little low but it planes in about 4 seconds and I cruise at 3800-4000 getting 28 -29 mph. I suppose I maybe should have got the 15p, I tried it and liked the responce and cruising speed of the 17p better. I have been assured that I would not see any damage to the F200 with 17p prop. Again apologies for the late responce. Cheers, trapper
