my 500efis are side by side and putting aout 615-625 hp, xrs and now turning in, top speed this year was 76.8 on GPS. 26 stock pitch and 1.5 drive. Not the highest hp boat out there by any means but very reliable. after turning in the bow carrys much better and the boat has a crisper throttle response in mid range. I laos noticed that at 55 mph my rpms are lower than they used to be so to me that means it is more efficent. if anything is different around the dock, I sure cant tell and at least in mine the current is a bigger factor than anything I have done to change the boat.

So for me it was worth it, I will put on labbed props this summer to see if I can get any more, but who knows.

Brett did my props and I will tell anyone looking to go faster to start there. I started at 74-75 and now run 78-79. I was thinking about having him bring up my rpms a little also.

my 35 t/s i had em in and picked up a tick but it has no notch... notched 38 t/s spin out per the experts and running in snot

The props on my my 39 Top Gun are turning in (staggered engines). We also had them turning in on the 2000 Top Gun (TS, side by side) and 2003 Gladiator (staggered engines). All three of these were set up with the props turning in from the get go and I never tried them with the props turning out so I cannot tell you what difference it will make. I can tell you that they do work fine turning in on a twin step though.

As for a straight bottom, we tried the props turning out on my old 45 Apache before we decided to turn them in and leave it that way. Turning them in provided the boat with more bow lift and it actually seemed to handle better as well.

If someone doesn't mind a rookie question...

What does it mean to "turn in" your props, and why would it effect docking?

Starboard prop turns CCW, port turns CW. ( when viewed from the rear)

Reverse seems to have less effect than
when they're turning out.

I've found that leaving the drives trimmed
slighly positve helps handling a bit, when turning in.

I'm spinning in. (89 Cafe) Better all around except around the dock. Docking will take getting used to.

Big difference on mine. Turned in last year and gained 4mph top end. '01 Tiger straight bottom. 750hp ea side by side with IMCO Extremes and extension boxes. No problems docking.

nice! whats top speed with the 750's? what type of boxes? straight back or upswept..any pics?

Staight back boxes. I just put the engines back in from a full Ron Potter rebuild and only have about three hours on them so I don't have top end #'s yet. Before the rebuild and I think about 50-75hp less per side my gps top end was 86mph. I sure am hoping for 90mph but........

Pics and more numbers soon.
