Love it. Just love the classic lines..Havent seen a closed deck manta in a long while...

If they are high enough to be sucking air in the water pickups then nose cones probably won't hurt, especially if you can go higher.

That's what I was thinking. With a straight edge from the bottom of the boat it comes to just below the bottom of the water pickups, so they are def too high. The nose cone is in the sweet spot right under to bottom of the boat. I will post pictures of before and after with the straight edge to the water pick ups. Water psi now is between 10-12. I would like to see 15-20 at higher rpms.

Thanks everyone for your replies. Thank you slpcamaross97 for posting my pics. Will be updating my membership asap. Tom

That's an swesome boat...Love the classic and loves rough water...good luck with it

Just installed low water pick up. Bobs nose cones. They look awesome . Hope to run the boat this weekend. I feel confident they will solve my problem.

That boat is gorgeous

Gorgeous! Wish I would have seen this post earlier. If you glue up/close off the top half of your stock intakes you'd have been done. Have done it successfuly tons of times.
I don't want to jinx you but every heavy Vee bottom O/B I've added nose cones to has slowed down and forced me to run full up trim to fly the bow when I didn't need to previously.
Where are you/boat at? Pix's look like Fla??

Regardless, best of luck on a gorgeous rig. And, more pix's please.
