Re: Stiletto Advantage Q
Manufacturers do indeed focus on prop efficiency and intended use. In the past number of years props have become very specific. There are props made for general purpose and purpose specific props. Props made for planing hulls, non-planing hulls, props with bow lift, stern lift or overall lift. There are props from the same manufacturer that are made for pad bottom hulls and different props made for air entrapment hulls even if both hulls target the same speed. There are props made to run at a higher X dimension than others.
Case in point are the Stilettos you mentioned. The Advantage Q has less rake than the Advantage which makes it a better choice on a heavily loaded hull. The Advantage with more rake makes it a better choice for your application.
"Back in the day" an engine manufacturer offered, for instance, only one 17" prop for a given engine size. No matter if that motor went on a planing hull, a barge or a pontoon. Those days are long gone thankfully.
