Trim question

[ericmillsaps]

Noticed on my gauge that my motor only trims up half way and that is it. Therefore I’m not getting my max rpms or the lift in the front end I want. Out of the water she goes all the way up fine. Low on fluid? Won’t go up over half way while running under preasure

Checked everything, fluids also. Had a small air purge when I took cap off. Is that normal? Gauge I would say is right or close. When she quits trimming motor is setting just a little over level and nose barely in the air. I’ve tried different props even smaller pitch, rpms stay the same on the big end.

check fluid at full tilt all the way up
