merc 135 tilt/trim issues

[rubbberduck]

Hi Im not sure if this is a problem or not but when stationary, at slow speeds or even on the trailer the tilt/trim allows the engine to go all the way up and all the way down but when at speed it will only go up to a certain level and when I start with it trimmed quit high and acceletate, it lowers its self!! To me it looks too low in the water and should be trimmed higher. Is this normal? Any thoughts please, many thanks.

Look at your clamp. If tha TnT has 3 cylinders (one long, two short) its actin' normal. Tha large cylinder is tha tilt, travels full range of in and out but will not hold motor under pressure (gassin' it in gear). Slightly more than idle is normal it should hold but that's it. Tha two small cylinders are are tha trim function and have limited extension for out That's why it sounds like it "changes" gears when ya run it in and out outta tha water (trailered)..
