Been using white lithium grease in the aerosol can for 25+ years with great results. It dries with a waxy finish that will last a long time. Great under the cowling and on elec connections

Thanks guys...Boeshield T-9 and 656 it is.

BTW motor came in ...I see the bolts they are talking about. I am keeping the motor inside till my garage space is setup for it, but once outside I will start spraying those bolts.

Thanks for all the ideas..

Corrosion X on O/B and any electronic components such as battery terminals.

Corrosion Block, all over it before it goes in and when it comes out. Shines like new. Eats any existing and prevents any from forming.

I'm a big fan of fluid film. I use several cases a year. But imo, it will make a greasy mess of your outboard. For an outboard, I would use Boeshield as others had mentioned.

I have always used Boesheild especially on new motors. It can take some time with the tube attached to get into every nook and cranny but it's worth it. Besides, when I buy a new motor I don't mind getting in there to get familiar with every inch of the motor.

656 does the trick for me after each trip the last 4 years.

You guys should check out CRC's site, they make specific products for corrosion protection, 656 is not one of them.

I have a 1994 Johnson on one of my boats and have used WD40 from day one and the motor still look new. I spray it on maybe once a month in boating season and when its put up for the winter.

I personally like CorrosionX. Wasn't particularly fond of the waxy film that Boeshield left behind.

Corrosion X green for heavy duty film application like on trailer hubs and axles and leaf springs. Corrosion X red for motor, steering cylinder, electrical wires and connections. I also don't like the yellow/beige film left behind from the T9 Boeshield. Although it works equally well as the green can of Corrosion X.

Used Silicon spray after every wash on my OB for the last 18 years and no corrosion.

656 is a lubricant.
That's what I like too. If I want one that stays liquid then I like Corrosion X

I sprayed my bracket, trim motor and lift rams. Carried to shop he looked at it quickly and said my seals were gone. I told him to look again I sprayed with fluid film he had not seen anyone do that before. It does make a mess but it will protect I like it.

Yamaha recommends silicon spray... what's the difference between this and other products such as CRC Heavy Duty & Corrosion X?

Was told by my Suzuki Dealer, do not spray 02 sensors.
