Nice work, I worked with Mike at Harbor Marine this past summer for that exact transmission swap in a Catalina 30. He was awesome and the guy knows everything I swear. I swapped the HBW50 Hurth for PRM 60. It has worked well and was not difficult even though it was a PITA. It fit well, I did engine mounts as well and this helped. I wish that I could be more confident in my shaft alignment, but so far is doing ok. I had the bracket machined in aluminum at a fab shop. Same cables worked although I had to swap the shifter direction as well. Nicely done.
Helpful video. When I spoke to Harbor Marine today, they said that they no longer sell this transmission because of a terrible high-pitched whine...have you experienced anything like this, and 3 years later, how happy are you with this transmission/gearbox?
I'm about to do the same exact conversion. Well done btw it doesn't look like an easy swap. Do you happen to have the drawing of that backet? I ended up calling harbour marine and they said some of the prm60's have a high pitched squeal but others are apparently fine. Are you happy with yours?
Yes happy, no squeal. Don't sweat the bracket. Ask harbor Marine to send you a template but even if they don't I expect you can estimate the dimensions and cut what you need out of mild steel.
@@guentherfeth350 I might find it, but really it would be easy to guess at the dimensions once you are looking at the PRM60 and how your cable comes around to it. I probably made mine out of 1/4" flat iron stock, spray painted.
@@myfriendbo5458 call Harbour Marine in everett and they should be able to tell you. If not, PRM itself responded to my emails. Give your engine manual a good read and understand whether the connector plate is compatible.

No whine, no issues. I run it at max 3000rpm. Interesting info though, thx

Where did you buy the PRM 60? do you know if anyone sells this closer to Ontario, Canada?
Harbor marine in everett, care of stem to stern in vancouver.
@@lutherdriggers Thanks or info. Do you still have a copy of the bracket for the shifter? I have a Catalina 28 mk2.

Hey buddy would the prm60 work as a replacement for a zf10n??
