Not much to be found on this boat and motor. The x18pfc is basically a x18pro, but a crappie version. It has a large livewell in the bow and double seats on the front deck.
I have a 2019 and bought it packaged with the 115 SHO. Top speed 1 person was 46mph, loaded and 2 ppl- 43mph, 2 adults loaded and a child 41mph.
Repowered to a 150SHO, 6" Atlas hydraulic:
Ran a Laser 2 23p and it was way too small. No lift, 53mph empty and early against the rev limiter.
Found a new 24 Tempest. Now we are talking. I didnt have a second person but I filled the front and rear livewells and had full load. It liked 5" ptp (I guess the bow weight liked the extra bite) and slightly under full trim for max mph. RPMs ran 5600 with or without the livewells full. 56-58mph loaded with or without the livewells full. No chine walk and drove like a dream.
A 23Tempest would do fine on this boat but I'll keep this 24p.
I also ran a Scorpion 15 1/8x24. They say those props are stiff by 2 and it seemed to be. I could only turn it 5200 at 56mph. The boat chine walked and steeing was hard. I think a 21 Scorpion would have been an option.
Hope this helps someone wanting this boat with a 150. I couldn't find anything on it. Safe boating all.
