Re pitched prop doesn't work anymore .

I have 2 props a 17" pitch and a 19"
The 17 allowed just a bit too many revs , and the 19 not quite enough when loaded a bit .

So i sent the 17" pitch prop to Steel Developments to re pitch to 18"

Tried the new re pitched prop saturday and its just cavitates when trimmed out where I normally cruise . If you go from about 3/4 throttle to full it just slips again .

At wot the revs are wantinmg to go over 6000 . Its as if they have re pitched it to 15 .

The prop was returned re painted looking like new , but the blades appear much thinner and sharper than before ,and there appears to be fine grinder marks visible .

I rang steel developments and told them and really just got some flannel that the prop probably just didn't suit my boat ,and re pitching envolved bending the blades not grinding . They tried to say I had damaged it or dropped it and bent a blade , which I haven't .
Before it went it was fine just a little undergeared unless loaded or towing . They want me to send it back for them to see , but I fear that will waste another 12 each way postage on top of the 57 its allready cost , plus I no longer have useable spare prop .

Any ideas what they have got wrong and what I should do .

You expected it to perform midway between the 17" and 19" which it does not. Tell them to sort it out at their own expense, or you'll spread a load of shit about them on a popular boating forum.......Oops, too late

If they do agree to take it back, take lots of photos of it first and e-mail these to them before sending it back, to prove that it arrived with you in the same condition as they sent it. Are there any local prop specialists who could take a look at it and measure the pitch, blade profile, balance, etc?

Are you 'avin a laugh?!!! The local 'prop specialists' down here also shoe horses and make gates.

Sounds like the may well have sent you back the wrong prop. Why all the grinding marks? Did the prop require re-dressing aswell as re-pitching?
Poisonally, I don't particularly hold with all this re-pitching business. I know that tuning race props is the done thing, but that is a process that can be checked and re-checked by running the boat until the desired result is achieved. I wonder how sophisticated the process is at Steel Developments. It only takes a slight difference in the individual blade pitches to cock it right up.

Not exactly local , I know ... but closer to you than Steel Dev. Is there any chance that you'll be in the Poole area? I've found Propeller revolutions here to be very helpful and they've got all the kit for measuring the prop.

I'd have to agree, I've used Propellor revolutions in Cobbs Quay for years and are very good. And they don't tend to have many good things to say about some of their competitors.......

Just tell them what you want - only problem is they don't open Saturdays.

you can try BT Marine in Newton Abbot, they've been recommended to me.
I have a similar issue in that I had a SS prop rebuilt after I found a pot line and its nothing like it was before.

Others on here have posted postive comments about Streamlined Propellers in Aldershot. Tel 01252 316412. Not local obviously, but may have some ideas.

Interesting, I was going to take my bent props back to UK and send them to SD for repairs but maybe I will just dump them and order a couple of new ones...
