What weight of oil should I use?

[m_sherman211]

What kind of oil should I use in my boat? Its a Liberator with a chevy 350.
I've been told to use sae30 and 25w40.
I have no clue on what weight and brand. Any suggestions on what works best?

that is the weight
30 and 25W40 refer to SAE grades, i.e. weight, and either of those is fine for 3 seasons boating

No,No,No!!!

You must run exactly what the manufacture says to use. If you do not pay for the high dollar oil that the manufacture says to use, your engine will seize up as soon as you turn the key. You have been warned...
