Well after 2 days of boating with it in the #2 hole I think I will keep it there for now. Did you see a big difference when you went from 3 to 1? I am running a 5.7L MAG.

Yes, the bow felt like it was plowing more in hole 3. Like you had a lot of weight up there. Not bad or crushing at speed, but from 0-10 it was noticeable. Not sure of the weight difference in our boats, I do run two batteries in near the stock location, and 50 lbs or so of audio and misc. in the engine compartment. Almost wish I would have ordered 60 lb piston as I see that others did. That way I would have some adjustment. I wonder if having the tabs lower/nearer to centerline causes more lift? Anyway hole one for me seems good, I'll make some wot passes and see if I decide to switch Pistons. I will also probably be buying a new prop as well. A lower pitch 4 blade would suit our use of the boat better. I bought the boat from my dad who used it on a 12 mile long lake, we live on a 200ish acre lake so not so much wot time!

I did email Nauticus with size recommendation. Seen that they have traded some others out. I will shoot them an email to see what a 80 hole one lines up with a 60.

Well Grego at Nauticus wants me to try hole 1 before we swith out to the 60's. You might try emailing him. [email protected]

Meant to say hole 3 in my earlier post. Hole one seems ok, will have to see if I lost top end though. I was thinking 60's just so maybe they could be set mid range again. Maybe I'm overthinking this, but I was planning on having two settings for the tabs. Normal for 90% of the time and when we really load it up a heavy setting. The pins are super easy to adjust, so I was going to order a spare pin or two. I think that ultimately if I don't lose more than 2-3 mph I'll stay with the 80's then if I'm loaded heavier it should be perfect. I'll keep you posted. If you do some wot passes let me know how close you are to your old max speed and what hole position you ran. Thanks

In hole 2 I increase my max speed to 47 from 44 with the whale tail. I like the idea of a few spare bolts and nuts just in case.

Thanks for this post guys, i noticed my bow aiming very much downward during cruising. So, hole 2 lessens the angle?

I was thinking about getting a 14.5" x 19 x 4 as a back up prop for Lake Powell, but not sure that would give me the power I need for water sports. Thoughts?

A buddy of mine has a crownline and went up to a 19p from a 17. He loves it. 21' boat with a 5.7 clocked at 55 gps on a river run. And can still easily pull up wake boarders.

That and trimming up your engine. It was way scary when I was at WOT with the engine trim all the way down
