I'm looking at a boat that has the props turning out. The owner said that with the props turning out the boat will be more stable. With the props turning in the boat will get more lift and be a bit faster. I am new to all of this. What has been your experience experts?

My 35 Lightning has the props turning in and can be a little challenging to maneuver around the dock. I haven't tried these turning out yet. My previous 28 Donzi was only about 1-2 mph faster turning in but docking was so bad I always ran them turning out.

It varies on the boat. Best to provide specifics on the boat, length, power, hull, etc.
Is it staggered or side/side setup? That matters. Step bottom or straight bottom matters.

In general, props turning in provides more stern lift.
In general, props turning out provides more bow lift.
In general, props turning out will be easier to maneuver around the docks vs. in.

On my single large step 32 I tried both.

Turning out didn't seem to make much top end difference but in the mid range it wanted to hop more. I went back to in.

As for docking, I just trim out with them turning in and its docks fine. You have to trim out, if not the water just hits the transom and nothing happens.

Absolutely true!! Most times when starting up your boat most put their drives in the full down or in position. When off plane and having the drives tucked all the way in the reverse thrust is directed at your transom and forward thrust is headed toward the sea floor. If you bring your drives up when slow speed maneuvering the thrust is pointed fore and aft (parallel to the boat bottom) which gives you much better turning leverage. So inward spinning props are not necessarily a problem docking, you just have adjust for your boat handling characteristics.

Spin them in to win!

A lot of the earlier single step 35s were set up with Hydromotive props. It’s my understanding that the Hydromotives didn’t give as much bow lift as the Bravo props. I set my 35 single step lightning equipped with a pair of blower motors with an 18” X dim. I’m curious if the boat would perform better turning out vs in. The boat runs a little over 100 now with Bravo 32s.

Turning in on top as Reggie set up these boats is for best performance. Same is true for staggering engines.. No one spent more time working out the right set ups for his boats to perform.. Don't try to out think the greatest. In Reggie I trust.

As a Fountain owner "In Reggie you should trust!". Been a Fountain owner for close to a couple decades,, couple different hulls, and I will tell you that the boats ran well as they were shipped. Spin them in! Learn to dock them as they run best! Hydromotives are some som***** good props on the single step hulls!
