Ericson 35 - 15 inch prop

I have an Ericson 35, that previously had a had a 2 bladed 14 inch prop that performed poorly in reverse and in heavy seas. I purchased an EWOL 15 inch prop this past year and installed it this past Spring. Initially the pitch was set too high, but after a couple of in water prop adjustments, the prop has been performing beyond expectations. Sailing speed has increased and reverse performance now exists. Cruising this summer through Woods Hole against 5 knots of current the prop proved it's worth. The biggest factor that sold me on the EWOL was the ease of pitch adjustment, something that is hard to guess right the first time. I would highly recommend the EWOL feathering prop.

EWOL sur Sun Odyssey 36/2

J'ai choisi une EWOL, toute inox, par rapport à ma tripale fixe, gain sous voile +0,7 nds, gain au moteur 1 nds Le plus surprenant et, lors du passage de la marche arrière, la puissance du freinage !! Çà m'a terriblement simplifier les manœuvres de port. Elle est belle, indestructible et pas trop chère. De plus, le réglage de pas est d'une simplicité enfantine. C' est le meilleur achat que j'ai effectué sur mon bateau ces dernières années !

Je possède une hélice Ewol depuis un peu plus d'un an sur mon voilier Dufour 365 et je tiens à dire mon entière satisfaction à son sujet. En mode voile la trainée est dérisoire et en mode propulsion elle a rempli toutes mes attentes à savoir plus de fluidité et une incroyable facilité en marche arrière.J'ai eu aussi la possibilité de régler le pas sous l'eau avec une facilité surprenante, quand au montage et démontage de l'hélice c'est une jeu d'enfant.

Higher Speed and good maneuverability

We have installed the purchased 2 propellers on my Lagoon 420 Catamaran. The installation was done by the experts of Kremik Service in Primosten Kremik Marina, I was there personally there was no any concern or difficulty, they fit perfectly as you have promised. I have sailed the yacht back to my home marina Tribunj and I can confirm that the propellers really run without any vibration and the speed is about 1-1,5 knots higher than before and at maneuvering the torque is much better to both reverse and forward. I am very pleased about the purchase, thanks again for your cooperation.

My experience
I used a V.... two blade fixed propeller for about five years. Never had any problems with it. However I didn't like the fact that when sailing I had to have the drive in gear and have heard stories about when sailing fast it can actually turn the engine over backwards and suck in water (never happened to me though). I tried a few times to leave the gear in neutral, as some have recommended, but the engine would shake quite a lot and I didn't feel comfortable with that. It was explained to me that this shaking was a symptom of the large amount of drag that the fixed propeller actually has (which seems more than I would have thought).
Also I wanted to reduce drag when sailing (it is fun to go fast when conditions are right).
I did a huge amount of research about feathering vs. folding propellers and since my boat handles like a dream both in forward and reverse, I wanted to keep or maybe improve these characteristics. I decided that the feathering prop was the only way.
I started to research and compare all of the feathering propellers I could find and was at the boat show in Dusseldorf three years in a row two of which I spent a good bit of time looking and inspecting "hands on" the various manufacturers at the shows.
I made my final decision based on what in my mind was the best engineered propeller, also the most expensive, but this is often the case but not always.
Any way I mounted the new Ewol propeller this last June and although I think I would like to teak it a bit (an extremely nice feature with the Ewol) as I am getting quite easily and quickly to the high end of the maximum rpm. Without tweaking it I have a much better top speed, I have the same cruising speed as the V.... prop. at 2000 rpms. Reverse is better with the Ewol, I think because it is three blades instead of the V.... two. The sailing experience is very noticeable and a really makes me smile. Especially in light air. The boat just seems more "slippery" to me. Of course it is difficult to document with hard evidence, but I believe I am getting a good 1 to 1.5 knots in winds up to 20 knots.
Next summer I will tweak it a bit and report back.
Also I paid extra to get the prop polished (thinking that I would just keep it clean with a 3m pad). This was against the recommendation of Ewol. It was a mistake, so this winter I will rough it up a bit and use the paint they recommend.

Passport 37 Ewol 16 inches
I have a Passport 37 with a Yanmar 3GM30FV. Previously I had a 3 blade 16" fixed prop. I keep my boat in a marina in Newport, RI where I need to be able to maneuvre in tight spaces.
I do not know about Volvo prop but since I've replaced my propeller with an Ewol 16" three years ago the boat has definitively improved maneuverability, especially in reverse. 
I have to say that customer support has been excellent.

Ho cambiato elica
A vela - La barca è sensibilmente più scorrevole - L'elica va in bandiera subito, dopo aver messo in folle fa' pochi giri e poi si ferma. - Non posso stabilire quanto ho guadagnato in velocità perché dipende da troppe variabili che non riesco a valutare, però mi sembra molto più veloce e, come detto prima, è percettibilmen te più scorrevole. A motore - Finalmente il motore non forza più, la barca raggiunge la massima velocità a 3600 giri, prima la raggiungeva a 3000 giri, il motore scaldava, fumava e puzzava non riuscendo a prendere ulteriori giri. - E' praticamente scomparso l'effetto evolutivo in marcia avanti, prima la barca tendeva ad accostare a sinistra sempre più prepotentement e con l'aumentare della velocità - Inserendo la retromarcia la barca "frena" notevolmente più di prima - In retromarcia è molto più manovriera - Con mare formato e vento contro, da' molta più sicurezza pare che fatichi molto meno di prima ad avanzare.

Good choice
I don't know about Volvo propeller but I just bought an Ewol in May for my Freedom 32 to replace my ..... (maybe the worst propeller ever). I'm very enthusiast about the Ewol, everything they tell it's true. I have more maneuverability, more speed sailing and motorizing, and less fuel consumption. My boat is in Hilton Head Island SC and from my marina to go sailing I have to motorize out of the creek through Harbor River, sometimes against 4-5 knots of currents (sometime makes difficult also leave land from the dock). With Ewol the boat is so responseve and I don't need to fight to go out of the dock. I also gained 1.5-2 knots in speed and I have more time to enjoy sailing. I can not be more happy and I highly recommend this propeller.

Have an Erikson 38, replaced engine with Yanmar 4JH57 and could not find prop that would fit. After much research and frustration talked to Sergio at EWOL and he came up with a solution. Got the prop and installed it underwater with a diver. First sea trial showed need for less pitch. Took all of 5 minuets to change in water and did so 3 times to get it right. Result max speed up 2 knots, RPM down to 1800 to reach hull speed and sips just over 2 liters per hour. Have gone on 3 week cruse with Trawlers requiring a lot of motoring to keep up and many shorter trips in and out of tight mooring situations with cross currents and winds. The ability to keep power on and back straight has been a boat saver. Been sailing for 60+ years and this is the best prop ever had! Also with clean hull sailing speed up over 1 kt in 5-12 kt winds.
