Lagoon 450 Engine power control

I have a L450 with Ultraflex Power A motor control which fails a few minutes after the propulsion has been turned on. After 2-10 minutes the propulsion switches off and the light in the engine lever turnes off. Restart of the motors does not remove the failure.
Has any of you had the same problem, and what was the solution?
Spare parts for Power A system seems to be unavailable now.
I'm now considering if I should replace the complete control system with Ultraflex Power A MK ll.
Any here who has experience with the new MK ll version?
What brand and model of power control is used in the present version of L450?
And what is the experience with this new system?
Thank you.

Re: Lagoon 450 Engine power control

Our 2014 L450 is fitted with the Power A MarkII's and after 18,000nm (or a 1000 engine hours) we haven't had a single issue. When I purchased the boat I had heard some horror stories about Ultraflex failures and took a punt when I ordered the boat, knowing of the updated MkII model, however I saw the benefits of having helm and salon control. I did purchase a spare PowerA MkII motor unit and shifter and fortunately they sit comfortably and dry in the spares locker. There isn't much maintenance to do except ensure the gear alignment is correct, greased telescopic cables.
