270 power trim issue

[tmcboat]

Hi All,
anyone ever worked on a 270 power trim unit?
It was working fine last September but this past weekend when I raised the lower unit up it slowly would go back down- need a drawing with the Volvo penta part numbers
can I run the boat with the lower unit all the way down or will the lower unit raise up once the boat is underway? I can put a lower unit brace on and raise the lower unit up when I am trailering the boat.
your thoughts and suggestions please
thanks,
tmcboat

The 270, 275, 280, 285 does not have power trim.

The 270T did, and the 280PT did.

When in gear,going forward,there's no way l/u is going to raise on it's own
