Re: Universal 5424 transmission
You probably will not like this suggestion, but; if I had to replace the Hurth 50 transmission on my O'day 35, I would probably bite the bullet and upgrade the Universal M25 motor and the trannie to a Beta Marine 25, or (maybe) a Beta 30. These are based on Kubota blocks, just like your Universal.
The problem with changing to a different transmission is that it will likely change the entire geometry of the prop shaft and the motor. As long as you gotta make a change, you may as well upgrade the entire system.
Another option may be to locate a used transmission. There are at least 2 available on eBay right now.
