Default Motor oil...

I did a basic search and did not manage to come up with much. I've noticed on some of the other forums I frequent (thumpertalk, CBRforums) there are some pretty good discussions/opinions/ideas over motor oil, filters and intervals of changing it. Things like brands, conventional/ synthetic, wts, additives, etc.

What is everyone running in their Mariah? ( or whatever make your boat is!)

    I run amsoil in both the engine and outdrive. I change it twice a year or whenever the engine oil changes color. I put on an average of 60+ hours a year tho. This year was right at 100

    I'm glad to hear good oils so far! Sold Amsoil for two years and still run it in the bikes.
    Would like to give the Purple a go. It is sold at the local shop where as I'd have to order Amsoil now.
    How about the weight of the oils?
    All of my fluids are either Merc or Quicksilver as of now.

    I have an '09 18' F/S Mercruiser. It has 179 hours on the engine. The service department recommended changing impeller along with the oil & lube service. I'm not having any problems at all, and was thinking about only the oil and gear /lube service. What are your thoughts? Thank you.

    Ok, so I'm looking at approximately $500 for oil/gear/lube service and impeller. Does that sound about right?

    Thank you.
