What kind of engine oil and weight for a 1999 bayliner Cl 1950?-gctid374367

[Guest]

Hi i have a 1999 bayliner and was just wondering what weight oil i should run in it because i hVE 10W 30 in it right now and the lifters make a little noise. Also i was wondering what weight outdrive fluid i should run?

you gave no specs on what motor, drive, etc you have.

1950, I am guessing a 3.0 or 4.3 mercruiser alpha. Use whatever merc recommends, you can check their website or search. I just buy what my mechanic says from merc at the store. For the engine and drive.

I can tell you now, its not 10w30.
