The Yamaha prop selector recommends the Ultima 4 14.25 x 15 for fuel econ.
I am looking for stern lift to get the bow down.
What was you experience with it?
I don't think it will help your issue and could make it worse.
I am not sure why you feel the need to get the bow down , perhaps it is way up, more than it should be when planing.
The first obvious adjustment is motor trim but I assume you have tried that. Trim tabs would help at speed. Shifting weight or reducing aft weight will make a difference ( e.g. see how things look on a half or less tank of gas versus a full tank). Is the problem more of an issue with passengers? (aft weight)
Motor mounting height could make a difference. Too high may cause the bow to raise when the motor is trimmed for efficiency.
The bow will rise as speed increases until the hull planes. If for a variety of reasons there is insufficient thrust to get on plane, I could understand your problem. In that case more thrust could help ( and a four bladed would normally provide more low end thrust) but I would be more concerned why you don't have sufficient thrust to get on plane in the first place.
What motor and prop are you currently running?
Describe in more detail the raised bow issue.
What are your current WOT revs?
