06 PIV with Etec - Tilt / Trim Bouncing

[huntfish45]

I have tried about everything I know, however I cannot get the tilt / trim to stop bouncing while being lowered. I have filled and checked tilt / trim oil reservoir. I thought it could be air trapped, but spent a lot of time working it up and down while checking fill level, plus I have been told these systems are self bleeding. Anyone else fought the tilt and trim bounce on Etec's?

I would post the question on this forum. They have some experienced guys on the site.

bouncing has to be air in the hydraulic system. See if you can find out how to bleed/purge the air out of it. For a merc you just go full up, full down, and repeat for approximately 5 times or so. Do not know about the etecs but I'd bet it is something similar.

torque on nut for tilt tube can cause this. my ficht has always done this since new and I tore it down a few winters back and torqued the tilt nut and it didnt help at all. ??? lower it down to first ram before moving or putting in gear really seems to help. lowering while moving aggravates the issue
