I have an OMC saildrive (detuned Johnson 25/35) that currently has a 10micron filter. Is this an appropriate size or is changing it advised? This is an inboard two stroke motor

Do you have an owners manual? What does it say? Do you have 2 filters, one on the engine and one in the fuel line between the tank and the engine?

The engine originally did not have a screw on filter such as this. The PO added a single filter and electric pump. He was too lazy to prime it by hand. I believe the original inline filter was removed. There's no oil filter since it's a two stroke
