That rig was designed to run a Predator PP style propeller (23-25) on the era of those engines.
Today a fury might be closer. It has a high bow rise for managing rough water and will not lay down fast. The hole shot times are not slow, though the experience is one where the bow falls faster, rises more and is designed to tac waves. Top end on a 175 Mariner should be in the upper 60’s to lower 70’s for them in that time range. Today we can’t say as the engine and boat are no longer new.
We may have an older PP style, if not then perhaps someone else inside the facility has one. Give the parts staff a call and see if they can help.
