Hurth Transmission

[deisher6]

Thanks Stephen.
Just scrubbed most of the bottom and particularly the prop.  The transmission is definitely slipping. 

Agree with your evaluation of the Universal and Kubota parts filks that I have talked to.

Thanks for the additional information.

Hi Charlie:
I'll check on the Hurt transmition in the consignment shop for you today. I'm going to pass on your "very generous offer" for the one out of the parts boat.
Happy Holidays

Thanks Bruce. 
Hope that you can understand that I would really hate to trade in one old transmission problem for another.  The rebuild cost is pretty steep for a Hurth, as far as I can tell. 

I very much appreciate your effort(s) and sage advice.

Then there is the problem of freeing up a couple BU's of cash from the CFO/Admiral.

For those with older C-27's, here is an update on Windrunner and a plan for resolution.

Wes recommended a mechanic, Captain Smith, who works out of McCotters Marina, Washington, NC. 

I called Capt Smith, he checked and has a Hurth HBW 50 transmission out of a Catalina.  He knew the boat that it came from and claims that it is nearly new.  He swapped it out on Catalina's dime when the owner complained of a problem.  It turned out that the transmission was not the problem.  He hung onto the transmission since it was nearly new, and wants $200 for it.  We agreed that I would call him in January and set up a time to bring the boat up to Potters Marina, across from Indian Island, on the north side of the Pamlico, where we will install the transmission, new mounts, and align the engine.  Looking forward to taking the boat up to the Pamlico. Hopefully do all this for around 1.5 BU's. 

Sounds to easy should I be suspicious?  Sincerely hope that the transmission has 60 or so nm left in it.

I will take some pictures and post the results when it gets done.

Charlie - will you have to haul the boat for the work to be done?

[deisher6]

Hey Wes:
No, I do not think so. 

I think that you can slide the prop shaft back 4-6 inches, until the prop touches the rudder.  I have a hose clamp on the prop shaft just to keep it from backing out of the stuffing box should it come loose, again. 

However we will see.  I promise pictures and a summary blog.

Merry Christmas.

boy has this become a trip down memory lane.
when I bought my first boat an Islander 36 on John's Island, SC; and proceeded up to her new home port in Norfolk, VA ... I eventually had an issue with a Hurth V-drive.  And being a tad too young and impatient, had it overhauled by either Metro Machine or Norshipco; I don't recall whom, it was coordinated by the local yard in Little Creek after I pulled the tranny from the boat.  What I do remember is the clutch adjustment wasn't right something like two or maybe even three times; I'm pretty sure they thought I was a young whippersnapper pain in the arse.  But with a digital tach I kept proving to them that it was producing a variable reduction ratio not a constant ratio, and therefore was slipping.
Once they got it right it was great for 10~15+ years until I swallowed the anchor and married, mortgaged, moved ashore.
Still have that boat, still have that transmission, both needing love and attention.
Also have a used Yanmar transmission in the shop from a raw water cooled engine block that rotted out of a customer's boat.  Would have to look at it's data plate in anyone needs it.  Tons of Yanmar, Westerbeke, Universal parts if anyone comes up short; mufflers, dripless seals; all the stuff that accumulates when a sailor turns repair tech and keeps going over 15~20 years.

On a different note, the kids are getting two "new-to-them" sailboats for Christmas.  Found two RC models on Craigslist for $100 (both, not each) which starting Sunday may become the most utilized vessels in the fleet.  I might be in trouble now, because if these count as "boats" since they don't fit in bathtub, that brings the fleet to 10 and there's only 5 kids.  Oh, that's ok then.  Previously I got away with owning 7 because "there was one for everyone in the family", then got to 8 because we're pushing two together (bad hull & good engine to be paired with good hull & bad engine; someday)...

Merry Christmas to All!

Hey Moonlight:
Thanks for the post.
What sort of digital tach did you use....something like a strobe light?
regards charlie

[moonlight]

yes a strobe with a piece of reflective tape.
I don't have one myself, but have been able to borrow one the two times in a 20~25 year ownership and then career that I needed one.

[deisher6]

Thanks Moonlight.  You got me thinking, a strobe set up not unlike the one used to set timing on cars.  Thanks for the scoop.

Well that did not work out as intended, crap it did sound too good to be true anyhow.   Called Capt Smith up today to lock on a date next week to install the Hurth Transmission as well as move the boat up to the Pamlico to cut down on mechanics travel time.  The Capt'n recalled that the transmission was not as he first thought, rather out of a boat that caught a log in the prop.  He said that he did not recommend using that transmission.  Wish that he would have told me sooner....

No problem, I had talked with Transmissions Marine Inc. of FL to price a new TMC Twin Disc MG340 in December.  I called them back, no problem except they did not have one in stock and it is 16 weeks for delivery from the factory.  I asked if they knew of any in stock.  They referred me to Sound Diesel and Joe answered the phone.

It took me a couple of minutes and a reference back to this thread to realize that I should have just started at Sound Diesel.  Joe does indeed have all the parts at reasonable prices and in stock! 

Parts are on order.  More later.

I would change your motor mounts if it hasn't been done in a while.
Easy to do when everything is off.

Hey Stephen:  I am with you there, already have them in hand....about $50 each.
Thanks.

Received my stuff today from Sound Diesel and engine mounts from Go2marine. 

I have been having problems with the flange on the end of the (bronze) prop shaft, you can see earlier posts when I had a new keyway cut.  At Joe's recommendation elected to buy a split flange. 

I hope that the new flange and proper engine alignment will quiet the engine down some. 

Will post more after installation.

One more flick!
