Hi Zai,

Your post already had credence. A long term CF member with 100+ posts. It's only the one-off new posts with very similar wording that is raising eyebrows

Re: Ewol vs Volvo propeller

I know some of you feel that the positive [posts regarding the EWOL prop are bogus, but I have no choice but to add to the enthusiasm for this prop.
I just removed my MAX prop and installed the EWOL prop that I purchased at the boat show">Annapolis Boat Show. It is a 3 blade 18" prop.
1) the salesman at the booth was very knowledgeable and is forthcoming with tech specs. He NEVER bad mouthed the competition's propellers...he just noted their strengths and weak points...doing the same for his product
2) the order went through easily and prop was delivered in tact and on time
3) I thought there was an issue when I went to mount the prop...technical was on the phone with me immediately and throughout the process..the issue was mine and not with the prop
4) the biggest advantage of this prop is the ease of installation/removal...1 bolt and it's in (no worries about losing the prop because of its engineering...losing it is nearly impossible).
5) the increase in performance was substantially better than my MAX prop

Next spring I will add to this post as I will be on a 3 week cruise in the Northeast and will have a chance to use it on prolonged periods.

So far....I am happy.

Re: Ewol vs Volvo propeller

Yet another new member who's only post is an endorsement of Ewol in this thread - and who has apparently no experience with the Volvo which the OP asks about.

Care to tell us a bit about your cruising experiences?

And how you found out about this forum and found this thread so quickly?

It's strange that we've only seen one such endorsement from a longer term member and he did have experiece with a Volvo - every other one is just like this - first post by a newly joined member, irrelevant to the question of comparing Ewol to Volvo and lavish with praise for their "new prop".


Sorry, I find it very hard to believe that all these Ewol purchasers suddenly find CF and just have to join so that they can post a commercial endorsement in this thread.

Re: Ewol vs Volvo propeller

Good morning StuM,

I saw multiple posts suggesting that testimonials on the quality and results of our products might be fake.
I can understand this doubt because I am also pretty careful when I need to evaluate an unknown product or service and read remarks....I know that there are multiple fake comments around.
For some time I decided to let go, because I thought that in the end you would have understood that there is no fake in what our customers were saying. But I can't continue to look the other way forever....

So now what I want to do is first of all to officially affirm under under my full responsibility that there is not any single fake post (that we know of... or in which we have any direct or indirect responsibility of) in any forum whatsoever, including the Cruisers Forum.

Second I want to explain to you why you see some posts that are from new CF users...It is very simple, since many months now we kindly ask our customers (either orally or in written) to leave a comment about their experience with our product and service. We don't solicit only "some" customers but "all" customers; as we believe CF to be one of the best sailing forums, we clearly suggest CF (among others) as a possible place where to leave their comments.
Although CF is well known, there is a high probability that our customer is not a CF subscriber as boat owners are many and some are subscribers to other forums, other are not at all interested by forums.... hence our incitation to leave a genuine comment generates new users at CF.

Third...we give a 30 days money back guarantee to all customers
Fourth...we give a 3 years warranty on any fabrication defects
All the above in full transparency...you can check our website www.ewoltech.com

I hope this give a little help in understanding, otherwise ...just try our product....it will be the best way to know the truth !

Re: Ewol vs Volvo propeller

I have just had a look at the price and its more than the established Bruntons prop. Yachties are generally a conservative lot so to ask someone to part with USD $3000 is alot.

Too rich for me, instead I would buy the Kiwi prop which is a 3rd of the price.

Why not make a cheaper plastic version?

Pete

Re: Ewol vs Volvo propeller

No experience with Ewol, but have been using Volvo Penta 3-blade folding props since 2008. Great performance forward and reverse, I have no issues with it.

Under sail I do need to lock the shaft by having the engine in gear, or it rotates; but I don't see that as an issue.

I like that blades are easy to replace with a single screw to release the pin, and carry a spare set of blades picked up on eBay -- just in case I ever damage one from a log or other debris.

Re: Ewol vs Volvo propeller

The advantages of the VP prop when compared to flat bladed feathering props is that the Volvo prop has very sophisticated blade geometry with varying pitch angle, high skew and a profile that develops lift. The result is very low noise, almost no cavitation when heavily loaded, and high efficiency. That's why the propeller blade shapes on submarine propellers around the world look like the VP prop.

For information comparing the VP and Ewol props, check:

Thanks for that Doug, but there's a typo there (missing "i"). Try

http://www.propelspecialisten.dk/dow...ison_chart.pdf

That objective comparison certainly casts light on the veracity of the claims in the manufacturer solicited endorsements earlier in this thread.

I feel like I stepped in dog poo!

I would like to say that even though the EWOL guy says he tells all of his customers to post or at least "spread the good word". I never had such a conversation with them. I think it is "cheesy" advertising personally.

My comments about the prop was from my experience end of story. I was at the boat show in Düsseldorf for a couple of years and a feathering propeller was on my list. I looked at them all and read forums
In the end the main two reasons I chose the EWOL was because of the engineering in regard to the stops and the fact that you can tweak the pitch easily without removing the prop from the drive.

Also to be fair, the propeller comparison is on a website for a company selling propellers and it seems that the propellers they sell have scored rather well in the testing. I couldn't see who did the testing.

In addition I think that the EWOL prop has been through a change in their blade design. Don't know when it occurred, but could be the prop test was before the new blades were in service.

Re: Ewol vs Volvo propeller

Just to be clear... we don't say to our customers to "spread the good word" we just ask to share their experience in full honesty (so this could be either good or not so good).
It is for us an extra motivation to provide continuous improvement on our service level.
I hope it's clearer (sorry I am not mother-tongued english)
We do this since 4-5 months and we have quite a good number of customers...so Zai...you might have purchased you prop before we started.

Re: Ewol vs Volvo propeller

Good morning Pete,

as usual I don't comment on competitor's products, there might be good reasons for choosing different solutions than ours.
However our product aims at being extremely sturdy, reliable and long-living, this means that we use only high strength materials (e.g. Super-Duplex steels), certainly plastic doesn't match with our philosophy.
Clearly such type of materials are not cheap, but we believe that going to sea and weather sometimes puts sailors in difficult situations and we want to give them reliable products to count on when they need them.

Re: Ewol vs Volvo propeller

....by the way Pete...

If your boat is a Moody 31 (probably with and engine 20 - 30 hp ?) I find hard to believe that your EWOL Prop will cost you 3000 USD.
If the range of power is more or less correct your prop will have a size range from 14" (2200 €) to 16" (2400 €) + transport (150 € from Europe to the USA)
As you probably know nowadays the € is weaker to the $ compared to some months ago....so your prop would probably cost you in a range from 2470 USD to 2680 USD all included door to door !

I hope this is good news for you !

I have a suggestion.
If you make an exceptional offer on a limited number of props, such as half price for the first two or three CF members to take you up on it. It might be a good way to get some props in the right hands and provide the right incentive to get the ball rolling so to speak.
