I should have said at wake speed, not sitting at idle. I understand and agree with you but I’ve never seen it go from 123 to 125 to 127 to 130 to 132 to 134 then down to 132 to 130 to 128 to 126 to 123 etc then climbs back up again etc etc like a cycle almost perfect timing every minute or so… like clock work but when I get into deeper water and lower the engine to run it stops climbing and falling…. only while moving at wake speed with motor trimmed up some… just seems different then what I have ever seen before.
