"Prop Steer" on the Aloha 28, What can be done about it??
« on: July 02, 2006, 05:14:42 AM »
Hello All,

We own an Aloha 28, and experience a good amount of prop steer to port when reversing out of our mooring.
I believe it a problem most A28 owners have, and deal with in different ways.

Has anyone switched out the standard prop for a 3 bladed one that is of a different pitch.
I was thinking perhaps a three bladed prop and a different pitch of the blades, may somewhat neutralize this pain in the neck characteristic.

Any thoughts on this would be greatly appreciated!!

All the Best,

Doug

Is prop steer all bad?

Our A28 does have significant prop steer in reverse. I haven't changed the prop ( a 2-blade Martec 13x9) so can't say whether this would reduce it, but have used 4 techniques to take advantage of this "feature":

1. I chose a mooring at our marina so that as I enter it I am turning in to starboard and have a port tie - as I turn in the natural tendency is for the boat the drift towards the finger, and then a quick burst of reverse pulls the stern across to it at the same time as the boat comes to a halt. When I'm reversing out, I want the stern to go to port into the "lane" so the prop steer actually helps.

2. After we had some correspondence about prop steer on an earlier list a while ago, Dennis Clarke sent in a Cruising World article he had kept which showed how to use prop steer to "Master the Tight Turn" - this is on the AOA website at http://www.alohaowners.com/pages/projects/turn/turn.htm

3. The prop steer only occurs when applying power. If you give a substantial burst of reverse power to get some way on, and then throttle back, the boat keeps moving but will steer in either direction.

4. Whenever I am manouvering or coming into a marina I'm visiting I use a combination of the above to request a favourable berth if one is available, plan all manouvers to ensure they DON'T require steering to starboard under power in reverse (I'll do a circle in the other direction if I have to) and to use the port tie + reverse to snug neatly up to the dock. I've become so used to doing this, I might now find it more difficult to manouver a boat that doesn't prop steer!

Not really an answer to your question, but just another view on prop steer.

The prop that most people I know seem to be happiest with is from Indigo.
It is a three blade designed for use with Atomic 4 engines, but as you have
a 13x9, it might do well.

I have experianced the change this prop made on a couple of boats, and it
is significant.  There is much less prop walk, and better acceleration in
reverse.

Call the people at Indigo - the are reported to be very helpful.  They have a
toll free number on their web site - www.atomic4.com/propeller.html
