Preventing Engine Corrosion

[Nautique Fan]

I have a 2007 236 and in the engine manual it states:

Protect engine finish from corrosion by periodically spraying the engine exterior finish with a rust preventative oil (such as WD-40).

What should I spray and what should I avoid spraying? Is WD-40 the best product to use?

Interested in this as well, was just reading that myself in my manual the other night and saw something called "Fluid Film".....for metal parts to prevent corrosion/rust. Says its a penetrant and lubricant...protects all metals, lanolin based, no solvents, non-toxic/hazardous. Anyone heard of this or used something else besides WD-40?

Fluid Film would be perfect. It's a staple in my garage.

I use acf-50. Pretty thick stuff compared to wd. I spray exposed surfaces.

I read a great article on the net about the best corrosion inhibitors. They did an independent study comparing about 40 different products. The study was very well done and without going into details Hornady One Shot and WD-40 Specialist Long Term Corrosion Inhibitor came out on top as 2 of the best corrosion inhibitors.

Hornady One Shot is made for guns and thus is a little more pricey. WD-40 Specialist Long Term Corrosion Inhibitor would be my top choice. Spray it on all exposed metal including the engine mounts.

I hit my motocross bike exhaust as well. It makes the bike faster.

Just a quick follow up question. Can you spray engine parts that get hot? And what about the exhaust manifolds?

Yes you can spray the parts that get hot.

Yes you can spray the parts that get hot.

Agreed. Those parts are likely to smoke and stink a bit when they first burn off the protectant, so don't be surprised if you see that.

The best thing anyone can do to prevent corrosion is to GET THE WATER OUT. If there's water left in the bilge, it evaporates on hot days. Since it has nowhere to go, it condenses back on to the engine, wiring, etc. This is where most problems start. If you can leave the hatch open a bit or Shop-Vac the water out of the bilge, you'll be miles ahead of preventing corrosion.

Thanks for the advise. The bilge is kept dry since we trailer to the lake and pull the plug each time so it drains well. I also open everything up after each use to dry everything out. Spraying the engine with wd-40 sounds like an end of season task. I appreciate all the input.

Oh you'll be just fine then. You're doing everything you should be doing to get water out of the boat. Opening up the compartments is a HUGE help. A lot of people get into mildew problems from covering a wet boat.

I always put in box fan in bilge overnight too after weekend to get everything bone dry....also use commercial air mover in boat overnight to circulate air, dry out everything, etc. I do that whether I cover or not. Works just as well with cover on

Holy cow, man. You'll never have any trouble with mildew or corrosion with all that. I bet that vinyl will still look new in 10 years.
