New to the boating world and have been trying to get this 2000 evinrude 50hp 4stroke/ Suzuki ready for the summer I’m trying to do any maintenance that should have been done boat sat for 3 years, it does run good took it out several times at end of last season. My question is the water pressure valve or poppet valve as it’s called by some is under the oil reservoir so I would have to take power head off to get to it, I’m sure it’s never been changed , should I change it or let it go unless I have a problem?

You are making a MISTAKE reading the parts diagram.-----The water pressure valve is NOT located where you think it is !

Where is it then? The manual says below oil reservoir?

So this should be the assembly, and where does this go on the block?
