Title: Needed 3 blade prop
Post by: mtullier on August 27, 2010, 04:52:51 PM
Hi, I'm looking for a new or used 3 blade prop 15x9 or 15x10 (M25 1987- 1").  Just lost a blade from my original when I was underway.  Looking for recommendations on where and who to buy this from.  Any help would be greatly appreciated.    Thanks,  Mike

You might want to consider using online yellow pages or Google for "prop shops" in your area.

Thanks Stu.  Looks like I will need to order on line.  No local shops have anything in stock.  I am told to buy from Michigan Prop.  This would be closest to OEM.  To confirm OEM is 15" x 9 pitch on 1" tapered shaft for M25 - 1987?

Before you buy new check the Catalina 36 classified section. then check the catalina forums and sailboatowners forums  in classifieds. then try Craigs list for the prop then try some of the used boat places and check boat parts in ebay. Google search. There are usually one or two for sale taken off similar boats where someone has upgraded to a folder. These are around $200 to $250. Good luck

Hi - I have a 15x10R 3-blade serving as a nautical paperweight since upgrading to a folder a while ago on my 88 C34 M25xp.

Please email me if you may be interested in possibly purchasing.

Kurt,

I put a feathering prop on 3 years ago and it went Tango Uniform this summer on vacation and I had to have a diver go down and remove it.  Luckily I kept my Michigan 3-blade on the boat and was able to have it put back on.  Might want to rethink getting rid of it.

Good point, Steve.  My PO left me his old two blade, which he'd replaced with our 3 blade.  I still have the old one on the boat, just in case.

That said, I'm sure there are most skippers who've put on feathering props and never looked back (pun intended). :D

FYI – 2 coats of a "marks-a-lot" permanent marker on the propeller will keep the barnacles off.  I heard this from the experienced guys in the boatyard.  Thought I'd pass it on.

Mike : Just make sure that the 3 bladed prop you get is not only a 15X9 or 10, but it is a Sailor style prop.  That's very important!!

Ron,

What is a "Sailor" style prop?  I've never heard that term before.

Rick : A "Sailor style" prop has much narrower blades than the normal "power boat" prop.  The smaller prop cord creates less drag under sail and does not lug down the engine when under power. 
That's the only style prop Catalina sells, where as places like Michigan Wheel usually hava blades of a much longer cord.   :wink:

Rick : Forgot to mention that the CORD is the measurement from the leading edge of an "air foil" to the trailing edge.

Not sure if anyone is still looking, but I have a 3 blade in reasonably good condition.

I've tried the "Marks alot" didn't seem to make any difference.....but it was a generic brand.  Maybe there is a difference.

If you notice MTuller's prop.  The cause of the broken blade is the leaching of the tin out of the bronze leaving only the soft copper.  Notice how red the prop is, that is the give away.  I had a similiar problem, turned out to be a hot lead on the dock.  MT you may want to ensure your dock is cold before you lose another one.

Ken has a good point and it could very well be the cause of the blade failure.

I've mentioned it a number of times, but it's worth mentioning again. You can only twist a casting so far so many times, and most prop shops BEAT the blade against a block to reshape the pitch!!  That's why I recommend a shop that uses "Prop Scan" over the wooden block technique.  
A thought.
