Anyone using a maxprop on their A4? Looking for sailing performance and some, well, ALOT better reverse. running a 11x7 3 blade now. i was concerned that the freakin shaft always turns albiet slowly when in neutural. anyone running a different transmission? like a hurth or similar?
Max - Prop anyone?

Aww, I dont think I asked my question very well. Ill try again. Im not thinking that a different prop will stop the turning of the shaft. Im aware that it will somewhat and is the nature of the transmission.
With the turning of the shaft, the blades will turn on the maxprop, causing it to not be in a feathered position. I dont mind any way except for when docking and etc. i was wondering what guys experience was with it'69 Newport 30 MKI Hull #20

Why would freewheeling be a problem in docking? There is no real power being delivered to the shaft, just the friction of the unit which is easily stoped by hand.
OR your reverse band is to tight. Neutral is not an actual POINT in the shifter just where the clutches are loose. It is the rotating friction that drives the shaft and like I said with very little power for unwanted thrust in either direction.

Take the cable off the shift lever at transmission then shift by hand using the trany shift lever to see if you can find neutral. If you can find neutral by doing this then try adjusting the shift cable. It may not be where you think it should be when the cockpit shift lever is in a certain position.
If you can't find neutral with the cable disconnected then you will need an adjustment inside the transmission as noted above.
If you can't find neutral at all you will eventually get used to docking and slow speed maneuvering while the prop is very slowly turning.

Max Prop
Take a look in the thread Titled: "Max Prop 3 Blade 12" prop.
I've had no problems with the Max prop and it has performed flawlessly. Plenty of torque to move the Ranger 33 with an old Atomic 4.
Reverse is like driving a car...point and go. Prop walk is all but eliminated. Now that does not account for wind influencing the entire movement of the boat.

Reverse
Be sure to keep pressure on the shift lever when in reverse as there is no detent like there is in forward.
Also, don’t be afraid to give the A4 lots of RPM in reverse. The tranny is noisy in reverse but that is just the way they are.
You should be able to get respectable Astern thrust.
