I have a 1980 24 foot SKV day cruiser with a mercruiser 260 and alpha one out drive with 1.47 drive ratio (picture attached) . Not sure what the boats weight is, but for these types of boats, it is a heavy one.
WOT throttle, measured with the tach in the dash is about 4500 RPM which seems correct based on the data plate on the engine.
I am currently running an aluminum prop that is stamped 15p (picture attached).
I am looking to maximize speed at 2600-3000 RPM's and the ability to get to that speed quickly. Would a different prop make a difference for me? In my reading, a SS prop may help some, but would a different pitch or number of blades help as well?
Also, I am curious as to why there are wear marks on the prop in the two locations shown in the attached picture. Does that indicate some sort of off balance situation?
Thanks for the info,
wR
