What is the setting for the tachometer on a 2016 Honda 50hp d Avalon pontoon boat which is 3 cly. I think my tach is bad it only shows 1500 rpm at WOT. I switched from 6p to 4p and now WOT is 2500 rpm. At 6p idle is 400/500 rpm.
I don't have power anywhere to the dash or trim. I check the fuse box with all fuses testing good. This is with the battery load tested good and positive breaker jumped. Any thoughts would be appreciated.
Thanks, Tim
