    Caymas gauge question

    Just picked up my CX21Pro today and haven’t been on the water yet. I cycled through gauge choices in driveway and one is labeled “BLOCK”. It measures in psi so I’m guessing Water Pressure? Can someone confirm? The motor is 250 SHO. Thanks in advance for your help.

    I never confirmed it but by watching it while driving, it appears to be water pressure. I have an email thread going with customer service and I will add that question to it. I just kind of forgotten and moved on, thanks for reminding me.

    I verified with Barry at Caymas that “Block” is measuring water pressure. I cannot speak to Mercs but it is true for Yamaha.
