Hi looking for advice before I go nuts.
Got a stern powr 1000 series pain in the @&'! Outdrive leg powered by diesel inboard mermaid turbo four 140hp.
It's always been hard to steer hydraulically even at 12knots so I looked into what could be issues like air in system or pump and ram issues.
Firstly I replace all oil and bled the system of air and also left it to settle over night and checked for micro bubbles, all fine. Take boat for test still stiff.
Disconnected ram from leg and I can move leg by manually pushing it side to side.
Operate the ram not connected to leg but with hoses connected all ok, check pin in leg to secure ram, all good moving freely.
So get a new sea star pump from hypro marine and fit with new hoses and fittings. The ram been inspected and seems ok with no leaks or obvious damage but I can't source a new one as it's an obsolete hynautic ram and even the right people say they haven't got anything to update this ram due to securing mount onto the stern powr mounting bracket, lancing marine could source one but at £800 for the small ram.
Anyway now with the new pump and hoses all back on and all air bled correctly on testing the steering seems even stiffer so any ideas what I'm over looking or doing wrong.
