I just bought my first twin engine a few months back, it's a 29 fever and I noticed the props turn in and I have been told by several people that turning in will lift the boat out of the water better and increase speed and I have had a few tell me just the opposite. I found some talk about it on a few thread on here and it went both ways. So I guess my question is, which way will actually give you more speed turning in or turning out?

I was afraid it would be that way LOL, I was hoping to turn them out and pick up some MPH!

Crude Intentions

The old phrase "spin in to win".

On Time

Turning in lifts the bow and allows use of less trim so you keep the stern up too. For a lot of boats this translates to 1-2 mph. My Fountain rides very flat and easily carries the nose. It needs a LOT less trim to carry the nose than my old straight bottom 33 Baja did. Trade off is for many boats its a little squirrelier at speed and harder to maneuver at the docks. Most Fountain hulls have been designed for props turning in so they don't lose stability at speed. Essentially all stepped 42s, 38s and 35s turn in.

Mine is a 29 with twin HP 500's and it starts to chine at about 78.

Make sure your tabs are level, that normally is 3 on your indicators but check with a straight edge. On the 32's if you bring tabs above level they will chime walk but neutral they won't.

I don't see any speed gain when I bring them above neutral.

I have checked them with a level to the boat.

I have a 29 w/454s that spin labbed hydromotives inward and I could get 75+ on a calm day. But it got hairy. It was right on the EDGE. One day I flipped them to see. The handling improved slightly around the dock but with that beak catching even the slightest breeze...didn't matter much. The speed dropped and the RPMs came up. I switched them back to spin in. In the past I have run unlabbed hydromotives and lost 4-5 mph easy and the motors run harder. Back to labbed spinning in.

How much speed did you lose spinning out fordf360?

On my single my prop turns in as well.
