99 Mercruiser 3.0 I/O SN OL318079 info

[TommyRox]

I have a 99 Sea Ray Bow Rider180 with a 99 Mercruiser 3.0 I/O SN OL318079 and I need to change the oil and spark plugs. Anyone know capacity, weight for the oil and best replacement plugs/gap for the spark plugs? Getting a manual soon I hope - any leads on that would also be helpful

Thanks in advance,

TommyRox

There should be a sticker somewhere on the engine with plug/gap info. Capacity and oil weight can come from a manual - when I went to the boat store the mercruiser oil only came in one weight option.

Thanks for the info...I was leaning towards Royal Purple - I run that in my bikes, truck and golf cart.
