Bob, If you have the factory prop it would work great at sea level, thats where they test them, some prop calculator are ok, merc has one, you RPMs should be between 5500 and 6k WOT, what ever pitch prop you have I would drop it 2 pitches, thats most likely the case for the selection you have available, advise stainless and 4 blade, better low end , waay better, I have one you could try depending on you pitch, I always run just below porpoise depending on waves, most efficient, Im guessing you have cable steering from you description, I bet you dont have all your fishing gear in yet either, more weight to slow you down, I like to have the low end more than top speed,

some shops might let you test drive a prop, not sure in your area, I would ask.

Mine is 2015 ranger vs1780 with a 115, I also have vessel view, Highly recommended, I can read fuel consumption, codes, time to empty, temps, its blue toothed to your phone,
