  • Outboard degreaser

    My 254 has a mercury 250 xl efi on the back. It runs like a top, but when you take off the cowling it is really greasy.

    My question is:

    Is it advisable to degrease the engine?

    and if so what do i use

    simple green?

    thanks

    The layer of grease is actually a good layer of protection from salt for your engine. If you remove it, you would most likely want to put something else back on so there is something between the metal and whatever salt enters under the cowel.

    I have used degreaser on my previous engine to remove the big chunks, but then recoated with T-9 or other spray coatings. If you are very concerned with how it looks, then you may want to clean it up, or just put the cover back on.

      Simple Green is a good choice, as is the Zep orange citrus cleaner that you can find at Home Depot. Both are good grease cutters and they won't harm the finish.

        Speaking of grease...I want to clean all the grease off my prop shaft.Its a duo prop set up and I had to cut one of the props off. There is a lot of mess on the shaft. Other than using piles of rags is there a spray I can use ? I was thinking brake cleaner..It leaves no residue when it dries.

          Clean her up and try a coat of "Fluid Film" on the critical parts. It's a great product that sticks

            I have found that the cheap spray brake cleaner or carb cleaner with a toothbrush works best. You can pick it up for $0.99 at the chain auto stores. Just don't get any on the lower unit, it's not paint friendly.
