I ran 55 on the gps with 21 pitch @ 4500 rpm ..I had a 19 on before that and it seemed like the 19 was faster.. What speeds are you getting with 19

Last year with two adults and full tank of gas I got 59 with a 23p mirage (Not plus). I'm running right at 4600rpm's. I tried a 25p and speeds were close but rpm's were down quite a bit. I had a 21p mirage before and was also getting 55mph. With a full load of people I'm definately slower. If you run with a full boat often I'd keep the 21. If you're load is fairly light and you want a couple more mph go with 23p. I've heard good things about the four blade bravo I I'd like to try one of those at some point. To do it over I might have stayed with the 21p for a little more power since we're always loaded down, I will eventually test the 4 blade bravo, I heard it would be more efficient on fuel, quicker on plane, but lose a few mph on top.

I run a 22p B1 and can spin it ~4600rpm with a 330hp 454. No GPS yet, but it's ~60 on the speedo. Cruise is low 40's turning 34-3600. Hoping to get some GPS numbers soon, and add a little hp to spin it another 3-400rpm. I've never run any other prop on this boat, so don't have any comparisons for ya, sorry.

Let me know what you hit on GPS when you get a chance, I'd be curious to see!
