Hi,I recently bought a 19ft boat that came with a 1985 Force 125hp motor 1258x5a. It did not come with a prop and I am completely new to all of this and have no idea what fits and what doesnt. What I do know is that it needs a 15 spline prop and im pretty sure it needs a non thru hub exhaust prop. Im just looking for my cheapest option and plan to use the boat for fishing and the occasionally will be pulling a tube. If anyone can give me model numbers or what size and pitch I need that would be amazing. Thanks
