    What kind of loads? Definitely seems 5 mph light based on RPM’s.

    What prop are you using? I run a Tempest 25 with a manual jack plate and power poles and get low 70’s on my 921.

    I'm running a 25 tempest as well with talons and hydraulic plate. I've even built shims to raise talons up higher than normal to make sure they not dragging and still no difference

    Running a 25P Fury4 on 2016 921 Merc 250, runs 70-74 pending how I want to drive it and loads. Definitely check to make sure full throttle and are the rpms you are reading off the gauge or a Merc Monitor?
