Re: Kiwi Prop

I have a Kiwi prop, next to no drag when under sail and good performance in forward. Putting the box into reverse is like pulling on a hand brake, I would like to find a way to reduce the pitch in reverse, but it works and I try to work with it. As for not having the room for a zinc, you could add a zinc to the hull and bond the shaft from the inside to the zink. its only the shaft you are protecting as the prop is all but inert.

Sorry. no.
I have a 1/4" between my cutlass bearing and the prop.

Couldn't you put a donut zinc ahead of the prop?

Re: Kiwi Prop

I was hoping there would be enough space in front of the Kiwi prop to install a donut zinc on the shaft. I'm still on the fence on this prop choice but will need to do something soon. I may just put my spare 2 blade bronze Astral prop back on for now and send my Max Prop back for reconditioning. I'm thinking from the experience of others, that's a costly proposition but maybe my best bet.

Re: Kiwi Prop

Hi Northstar, The problem with the Kiwi is that there is no place to put the prop zinc on a PSC as stated earlier. A possible solution would be to install a hull zinc and connect it to the prop shaft with a shaft brush.
I too liked the KIWI concept. When is spoke to the rep in CA he had no PSC 31's in his data base. He was able to "recommend" the size by the engine hp and displacement.

There are some exceptions. Autoprop increases the performance. I heard that the Gori overdrive too

Re: Kiwi Prop

I have one...really helped me in reverse vs the fixed 3-blade OEM prop.

One of the best upgrades I've ever made on the boat!

Lost about 0.5 knot - 1 knot under power, however gained about 20-30 sailing days a year. Before, I needed 9-12 knots windspeed to get going...now 7-8 knots and I get somewhere!

Re: Kiwi Prop

Most I know who have them are quite satisfied with the forward performance. On boats with smallish engines the out-of-the-box 'bite' in reverse was enough to stall an idling engine. Adjusting the reverse pitch with some screws seemed to help.

It's odd-looking in some ways, almost like a back-yard cobbled together thing but that's not a big issue.
