I have twin 150's on my Sea ray. One seems to have a slow leak for the trim option. Meaning, I have to constantly raise the trim while on the water...How do I fix this. Also, the same outboard is much slower in raising then the other, can this be fixed as well?

Thank you!

Maybe some of your seals are leaking. Here is the O-ring Kit for that motor. It is about $80

Check the wiring for corrosion that lowers the voltage, making the pump run slower.
