I believe there were several models. We had a M-25xP which was a Kubota 950. I have the three manuals and will try to attach them. My local Kubota dealer couldn't look up any parts for marine engines but could easily get any part if I had the Kubota number.

The M25 is the D850. The Kubota manual with Kubota parts manual, NOT the Universal, is located in the Catalina 34 International Association website's tech wiki. You can find it here.

I've used this manual for ordering parts from my local Kubota tractor dealer.

There's much more, here:

Their wiki has all the manuals, also cross-reference charts from all the Kubota blocks to the Universal engines.
