Offshore trim pump issue

Hi everyone,

Bit of a strange one here, have replaced the trim pump on the phantom 18 to the later type with the plastic resorvoir. The engine trims fine on the land with no leaks or issues at all, however anything over 5mph the engine won't trim up but will trim down fine? If your going slowly it will trim up fine. When the engines on the land you can stand on the engine and it trims up fine so doesn't appear to be a load thing. Has anyone else had a similar issue?
Cheers

Sounds like either pipes wrong way around or release screw is loose. Which way around are the wires ? Should be Blue up Green down !

I have had the engine trim tuck back in slowly under load. The engine would move easily in either direction showing no signs of a problem I.e leaks or speed of trim etc.
That was the ram seals allowing fluid to pass internally.
