Replacing trim pumps and I have had several suggestions on what to fill them with! ATF, power steering fluid, hydraulic fluid. Which is best? Thanks

We just had a thread on this a couple weeks ago. Pretty much boils down to your choice. Mercruiser says Mercruiser power steering and trim fluid, 10w30 or 10w40.
Others successfully use atf or power steering fluid which I use. Climate etc can play a part also. Up here in northern Michigan the lighter the better for quicker response.
