Hmmm, the website lists the M9 for the F150 to the F250. But also lists the one your referring to that mounts on the bottom of the cavitation plate with the circular cutout for the F150 also but it states its for boats larger than 21' with a single outboard on a bracket. So I called and the woman first said the M9 then came back and said the other one?? So Im still not sure? Anyone out there have either one on their F150?
thanks
