Does any one know how I can find out what prop I have it has stamped on it quicksilver 816314A417P my WOT is around 4200 on a 24' cabin cruiser. 5.0 L TBI mercruiser. Im thinking Im overproped a little . Have had the boat for several years and has always been like this. I do not want to repower now even though I know it is underpowered as it runs fine and will run 40 mph once it is on plane. Just want to get on plane quicker. Thank
