Sp Mk20/mk25

How can you tell if a MK20 reg has had the update to make it a MK25?:newbie:

of the Mk 20. Underneath you will see the HP seat retainer plug. On the original Mk20, it is a round plug with a large hexwrench (looks about 6mm) opening in the center to remove/install it. Based on the Mk25 schematic, that plug is hexagonal rather than round, so it must be removed/installed with a box wrench, and in the center there should be an adjusting screw for adjusting the IP. I assume the upgrade simply replaces the seat retainer plug from the Mk20 with the plug from the Mk25. I guess that only the serial number would reveal that it was originally a Mk20.

Thanks for the info awap. The yoke knob states that it is a MK20 but it was supposed to be a MK25. When I called customer service they told me that it has been updated and I wanted to know for sure that is was.

Did you purchase from Leisure Pro? I had the same thing happen to me. I bought what I thought was a genuine MK25, but it appears to be a MK20, with a retrofit. Looks like i'll have to do the inspection to see that a change was made also.

Yes I did. I was not to happy about it but when I called customer service they told me that it had been updated. I expressed my disatifaction about the transaction but I needed the reg. for a dive on the weekend and decided to keep it.
