Ok. So was not completely wrong with my thoughts. However I've sent an email to PRM and I am waiting for the reply. Thank you very much for your kind help. Great forum?

That was my first thought, but no it's not?

Hi folks. Thanks for your help. I took two pictures of the gearbox when I bought the boat. On the one picture with the two red arrows these are the Nuts where I think one of them is for draining the oil. But I don't know which one it is. On the other picture with the red and blue arrows I took the nut (red arrow) off but there is no dipstick. Could it be the other nut (blue arrow)?? The drawing in the manual is not very clear. At least not for me??? Next picture

Hi everyone. I'll be back on my boat soon and need to make on oil change on my gearbox. I've bought the boat a few weeks ago and finished changing the filters and oil on the engine, but got stuck on the gearbox. There is no dipstick and I don't even know how to drain the oil. If I pump it off and refill it, the level could be to high. So I would really prefer to drain it. How are you guys changing the oil on a prm gearbox?? Thanks for help and advice
