Gori or Maxprop

[Koeketiene]

Looking to get a new propeller - was thinking of getting Maxprop.
Though Gori looks good too.

Comments of experience with either much appreciated.

dunno the answer, but have been thinking much the same. Kiwi and Bruntons come into scope too.

I reckon there as many different views on folding or feathering props as there are about anchors .... God help us!!

No experience of Gori but very pleased with Maxprop with one exception.
The anodes on the Maxprop are poorly designed. The bolt holes holding them on are near the edge of the anode. Consequently the anodes don't have to wear mutch before they drop off.

I have a Brunton's Autoprop, which I like very much. However, I read many glowing reports of Kiwiprop, which seems to work as well according to various users and is about half the price of an Autoprop.

I have a Gori. It does pretty much what it says on the tin; drives a couple of tons of wood at more than 5 knots forwards, not quite so good astern but I don't think that's fundamentally because of the prop.

Very pleased with Gori 3 blade after 2 years. Light wind performance is much better, and reverse is OK. The overdrive gives good fuel consumption, about 2.5l per hour.
After a year the finish was as good as new, using Propshield.

Also pleased that the anodes are still in good condition, and the shaft anodes are eroding as before. Its one of the few boat items where I was glad I spent the money from day 1.

As Nick says, they all work and everyone likes the one they chose!

The fact that Swan only use Gori says it all.

Beautifully engineered, two speed facility seems gimmicky but works.

You buy something else if you cannot afford the cost of a Gori.

Oyster fit MaxProp /forums/images/graemlins/smile.gif

 

[Koeketiene]

Thanks for all the replies so far - keep 'em coming.

Kiwiprop is not an option - IIRC they're limited to engines of 50 or 55hp max.
New engine is 85hp.

We looked at both sorts of prop and eventually opted for a Maxprop. Been very satisfied with it. It is a beautifully engineered bit of kit. Swan us Gori, Oyster us Maxprop - so what? Maxprop is not cheap.

We chose Maxprop because we thought it had a better world wide parts and spares service.

 

[sailorman]

Meby Oyster have the same idea as you /forums/images/graemlins/wink.gif

Before you jump in where others fear to tread check out Steel Developments - I will say no more other than they are a nice piece of kit - it is your "dime" so spend iit as you feel fit - I think you know what would get my vote /forums/images/graemlins/grin.gif

Look at Autoprop

More expensive than either, probably a little more drag than the MAxprop, but infinitely more versatile and far better thrust characteristics

 

[gardenshed]

Feathering is the way to go
4 years with an old maxprop and I'd not have a folder or fixed again.
Gori or Maxprop, steel developments or Darglow's Featherstream: much of a muchness, kiwi if smaller engine /boat.
The only features that I would advise you to ensure you have are:
external adjustment of pitch (I can now re-pitch my maxprop in about 20 mins but have had some great foul ups learning!)
exernal greasing point (once your all set up, your annual maintenance is then just squirting in the grease

don't waste your money buying something cheap!

 

[charles_reed]

Far far better

to have a self-pitching prop like the Autoprop.

All the others suffer the same drawback, you have to set the pitch. This means their only advantage over a fixed prop is that they feather.

The Autoprop adjusts its pitch to the resistance, which, means you can effectively motorsail at low revs when wind is light, because it coarsens.

Re: Far far better

The self pitching character of the Autoprop IMO makes it a best buy, certainly I love ours which luckily came with the boat. Friends with a Maxprop took a very long time and several lift-outs before the adjustable pitch was correct but in their case the Brunton wouldn't fit in the prop aperture on their boat.

Re: Far far better

Autoprop does have more drag than either folding or feathering props.

Edit: also had a neighbour with an Autoprop who had vibration problems due to fouling not allowing the prop to precisely pitch each blade the same way.

Gori 3 blader transformed performance under power and sail on our Centurion 32. Gave us nearly 1 knot more under sail in all conditions; and reverse under power much more positive than with removed fixed 3 blader. Mainly used in low "gear" unless motoring with tide when higher "gear" very useful. New preowned boat has a Bruton Autoprop-not as positive in reverse although very good going ahead. Not much between them.

<<< New preowned boat has a Bruton Autoprop-not as positive in reverse although very good going ahead. >>>

That's a strange observation, as it's one of the plus points of a Brunton that the hydrodynamics of the prop are exactly the same going astern as they are ahead, unlike some others where flow over the blades is reversed.
