Another prop question
Just got a 212 captiva with 5.0L and alpha one drive. Had it out twice last fall and the boat ran at 5000 rpm and 52mph with a 21 pitch 3 blade prop. While the hole shot was fine for regular boating was a little lacking for skiing. Have contacted a reputable prop shop in Cincinnati, the only one. He recommends a four blade prop and gives me 2 choices. One four blade needs to drop the pitch to 19 to maintain overall performance. He claims for a little more money they have a Mercury four blade that will increase hole shot while maintaining wot performance and keep the pitch at 21. Assuming both of the above statements are true, my question is is their an advantage to staying at a 21 pitch vs the 19 pitch when changing over to a four blade. Appreciate any feedback I can get as I am ready to make the change, just want it to be the right one.
