I am attaching the write up my guy did who repaired my shaft log .... interesting.  I will attach some pics as well...

Spring 2021. Catalina 34 was taking in steady slow stream of water at time of launch. After inspection and tightening bellows, leak still persisted. Hauled boat back on the hard. Slid bellows forward and discovered the shaft log tube was almost destroyed, with it being completely split along bottom of it, with also a tiny amount of wear into hull( hence where the water was seeping into boat).  Could put fingers through bottom of shaft log tube. Stainless shaft was much out of alignment and had been wearing probably for quite awhile. Engine mounts looked normal and no signs of wear. Bellows and packing also showed signs of heavy wear. Proper repair would be drop rudder, remove shaft completely, bore out old shaft log tube, install new one and glass into hull. Adjuster came and recommended not replacing it but rather sleeve over existing tube with PVC. That caused me countless sleepless nights trying to figure out how that would be possible. Most of us know PVC and epoxy do not bond well together. Also shaft log tube was supposed to be 1 5/8 o.d. and PVC only comes in 1 1/2 and 2 inch inside diameter, with a rather heavy wall making it way over the proper o.d. of 1 5/8 i desired. A fellow mate at our local club suggested sizing up one of his tapered carbon fiber sailboard masts (we both used to sailboard in our much younger days). Miraculously it was thin walled and a perfect match! Fit snug over existing damaged tube and left me with exactly 1 5/8 inch o.d. I was concerned about cutting 3 inches off a 500 dollar carbon fiber mast but my matey assured me that although we often talk of sailboarding the gear had been sitting stagnant in his locker for over 10 years! So i made the cut and glassed  it in heavily. Got new packing fitting and bellows. Then came the hard part. Re aligning engine. Soaked mounts with PB blaster overnight. Freed up all mounts. The engine was sitting quite low in comparison to straight line of shaft. Hub jumped up a good 1/2 inch when i separated it from engine. I adjusted engine up until shaft looked as centered as possible in shaft log tube visually. Then slid shaft back out of hub and put bellows and packing into place. Then slid shaft back into hub and hub up to engine. Checked alignment with feeler guage (around .003) and torqued everything back into place. Launched boat and tested with a local boat mechanic present. He said alignment was perfect. To be clear i was lacking confidence or desire to tackle this job, and i did as much research online as possible on the subject. That led me to the most confusing part. That the boat will change shape, possibly drastically, in the water and would have to realign once it relaxes in water for a few days. ??? How would i see position of shaft in shaft tube with bellows all in place and clamped tight.
Research said remove hub from engine and use feel to see if it's centered in tube. So i did, and sure enough it changed and was off again. So i loosened mounts, and went at it again, until i felt shaft was centered in tube and mated with engine at same time. Then re torqued everything back into place again. We need to test run boat again to check for cavitation and probably will need fine tuning again with the feeler guage. For now she is leak free and floating peacefully at her berth. That is my story and i'm sticking to it! Take care everyone.

Going to send a final copy to the shaft log repair I started some time back... my guy Ryan Restivo wrote up a summary as requested by the forum... here it is:

Ron,

Can you send me your email and I will send pictures.  Had a video but unfortunately deleted it.... The surveyor said it was an east fix ... just get the proper sizded PVC to go over what is left of the shaft log and glass that in.... my guy says not as easy as that... still working on a solution.

My guy not seen anything like this before and local yards are swamped and can't send anyone.  I do have a buddy retired from local yard has promised to "oversee" the fix... just need to get right sized replacement log shaft substitute.  Does anyone know the inside diameter of that shaft log?  I ordered a replacement log but that would entail really tearing things apart to replace the whole thing.

Had the surveyor down from the Ins co. he said it was cracked... and he said it's an easy fix.  My guy who has worked on a lot of boats in the yard is nervous about the job.  We have an experienced guy as a club member who has worked in a local yard for years and is willing to help but he is not "familiar" with this.  I can send a video that my guy took and was hoping to get some local yard to send someone but they are all buried.  Let me know where to send the video.  Surveyor took lots of pictures but I have yet to get the estimate.  When I do I will ask him to send some pics as well.  There is some wear under the shaft log as well, motor must have been out of alignment.

Did you say I could order the shaft log?

Well, pulled shaft yesterday and alas, Noah and Ron were right it is a fiberglass issue not simply the rubber shaft hose.  Going to have another guy look see this morning.... any suggestions?

Thanks all... my guy gets back in town Monday... he was hoping it is the rubber hose, he replaced that once before some years back.  If it's fiberglass, he is nervous but that is the nature of the beast.  I'll let you know.

Launched the other day only to find the bilge at the floor boards two days later...water coming in at the shaft... slow but steady... its not the stuffing box.  I am back on the hard and my man (former Junior sailor of mine now 40) will be tackling the job.  Any suggestions as to what to look for when we pull the shaft?  My man says, "see what Stu and Ron have to say."  Of course we are open to any and only suggestions.

Truth be told....

I ordered a pump from Niemec Bros.... $385, $17 for the Hose nipple, and $4.00 for the gasket..  THEN I checked back on this website and found all the good info and part #s for Kubota... from you wonderful guys!!

So, I went a mile up the road to my local Kubota dealer and ordered the pump for something like $152.00  and it came with the hose nipple, no extra charge.  We  are installed and up and running ... and Niemic Bros said no problem returning and no restocking charge.

NEXT ...  in the process my air filter seems fahocta... (yiddish for messed up.. and I'm Irish)  Suggestions on replacing that?

A big thank you to all on this website... it is the best!!

Greetings,

I am looking to replace my circulating water pump... I have the Universal M25 engine which Catalina used for one year before going to the XP engine.  Stu Jackson gave me the source of Depco Pumps which I used for my water pump last year... will call them on Monday.  Any further ideas?

My macerator is blowing fuses... it is not the original ... I put in a new one about 10 years back... it is a Jabsco 18590-1000.  I see a kit for servicing that model but they say 2015 or later... mine older than that ... I see a lot of service kits for the 1000..  Most if not all of 18590 series are 2092.  Prices are all over the map.

Suggestions?  Help!

Took to my local guy.... $100 bucks... back in and working ... he said it was gunked up, corrosion etc. etc... something about the brushes.  I've used this guy for all boat electrics, starter, generator etc.  Always good.  Thanks for the replies.
