Has anyone adjust trim pump lift pressure? I have problem with new steel prop that trim doesn't have enough strenght to get up in high speeds. pressure is too low. There is no leaks. I have look it that there is three pressure valves in oil tank, bottom of the pump unit. I wonder the lonely one effect to down movement, but how rest two works? There is a steel tube and a brass tube. Can I adjust of those pressure valves and how?

Thanks for answers!

Sounds like you have a weak pump or bad ram. Just a guess

Pump can run either the cylinders are in the end, I mean through the end wall. so motor is not weak. Pistons seals doesn't leak because it will lift and stand up if I lift it lower RPM's. I think problem is in the pump

Do you know what kind of fluid is in there?

there is 15w-40 motor oil

You could try to switch to straight 30w, might help build a little more pressure. I would lean toward a bad pump though.

I think I will shim those valves, but I need to know why there is two valves witch connect to up movement line. Motor have enough power but pump pressure is worse. Does Bravos has different trim valve bodies?
