Once again i'm looking for suggestions from the forum....I appreciate the reply's.....
I just bought a 2005 220 that's been in fresh water....in a couple days it arrives and will be dry stored....but used in salt water...question is...shall I open up he engine cover and spray the various components down along with the electrical connections or not?....I assume it's a yes...there's several sprays out there for corrosion protection....what is the preferred product?.....thank you...
 
Sorry I cannot help, we are in fresh water and store in doors during the winter
 
I used a product from Yamaha call Yamashield. I use in on my WaveRunners and my just sold 06 Yamaha outboard. I have just like you purchased a lake boat and dry store it in Orange Beach and use in salt water. I sprayed the motor down with it. I do not know if it will help but my waverunners look like new and they are 05 models and we use them in Salt most of the time. Bigest thing is to make sure the marina flushes the motor after you bring it back. Mine washes the boat from the rubrail down, removes the drain plug, and flushes the motor and puts on the cover before it goes in the rack. When we return from boating we wash the inside of the boat and dry it and put on the foward cover.

Another product is boshield
 
I use "corrosion block" when store my rig for the winter. It's about $20 at WM.

Sorry I can't help either I just wanted to let you know about me as well. We boat in salt water and store our boat on land. I love Pizza and beer and my favorite color is green. Anyway, I use this.. http://www.mercurypartsexpress.com/us/corros-guard-p17.html

LOL as coffee is coming out my nose! I like pizza and beer too but green is not my favorite color. I agree with all posts, use something to protect your boat.
 
Sorry I can't help. We boat in salt water and are wet slipped in FL year round. My favorite color is clear.....

I use both Boeshield and Corrosion X, both seem to work fairly well but don't last very long. Remember to repeat the coverage often. I use my monthly coating as a look around the engine room while I spray. If anything is amiss, I can repair at that time as well.
 
CRC fogging and WD40. I boat in brackish and salt water and my bilge/ engines look excellent! You should use something no matter where you boat!
 
WD 40 lasts about a week....maybe.

I used Corrosion Block, which works great, but my local boat shop recommended I use the same Yamashield because it has a nice wide fan spray and covers an engine very well and quickly. I use the narrower Corrosion Block spray for the connectors behind the dash and for spot areas on the deck/dash that are starting to show corrosion (it takes early corrosion right off). I spray my engine several times during the summer months. Not much during the winter months (I use the boat year round) because I don't take it out as much. The engine looks like its never been used. I second the rinsing/hosing down/wiping dry of the entire boat after each use (I rinse the entire boat, not just below the rubrail). I do that with Salt Terminator (or you can use Salt Away) and the boat now looks like it just came off the showroom floor. Whole process takes me about an hour and I actually enjoy it (funny that), I guess because of the resulting clean and shine of the boat. And most importantly of all, flush the engine with the same salt neutralizer stuff.
 
I own a marine business and hands down its Corrosion X, regular and their Heavy Duty formula. I've used them all, believe me. WD-40 is garbage. ITS first ingredient is water. CRC not too far behind. I don't like products that dry to a film, like Merc Corrosion Guard and some of the others. I was turned on to Corrosion X from the dealer that sold me my Maritime Skiff. Its got a Honda on it and we all know the foreign stainless likes to rust. I've sprayed Corrosion X on this motor since day 1 in 2001 and this motor has no corrosion on it, and when I need to take something apart, it comes apart. I use it on all electrical items, like buss bars, switches. I also spray down everything in the engine bay of my 85 260 da. I use the Heavy Duty one for battery terminals, trailer winches, tongue jack swivels and pull pins, shift cables and linkage, etc. Read up about it on their website. I use so much of it, I became a Dealer for it. Their Extreme Clean product will turn the worst looking fender you have bright white. Another good product from them I tried this season.

Where did you get that from? It's ok to have an opinion, but geesh.....

What does WD-40 stand for?

WD-40 literally stands for Water Displacement, 40th attempt. That's the name straight out of the lab book used by the chemist who developed WD-40 back in 1953. The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion-a task which is done by displacing water. Norm's persistence paid off when he perfected the formula on his 40th try. Please see Our History for more information.

What does WD-40 contain?

While the ingredients in WD-40 are secret, we can tell you what WD-40 does NOT contain. WD-40 does not contain silicone, kerosene, water, wax, graphite, chlorofluorocarbons (CFCs), or any known cancer-causing agents.

What is the shelf life of WD-40?

Indefinite. While some products may have an expiration date, WD-40 lasts so long that a "use by" date isn't necessary.

How long does WD-40 last after application?

While this may vary depending on the application, WD-40 remains effective even after it appears to dry. The corrosion and rust protection ingredients remain adhered to the surface. External conditions may, of course, require additional applications of WD-40 for maximum protection.

I've heard that people use WD-40 as a cleaner/remover. What can it be used on?

WD-40 removes sap, tar, adhesives, labels and tape from surfaces without damaging existing paint. It's an effective cleaner for tools, equipment, and vehicles. Use it to remove splattered bugs from the front of cars. WD-40 will even help remove gum from carpet. Just spray, wait, and wipe with a clean cloth.

How is WD-40 different from 3-IN-ONE®?

WD-40 is the ultimate multi-purpose problem solver. WD-40 cleans/degreases, penetrates to loosen up stuck parts, prevents corrosion and is a light lubricant. 3-IN-ONE, with it's special drip spout, enables you to lubricate without any overspray or splatter. 3-IN-ONE is ideal to use on tools, rollers, hinges, in-line skates, wheels...nearly everything that moves.

What does WD-40 do?

WD-40 fulfills five basic functions:
1. CLEANS: WD-40 gets under dirt, grime and grease to clean. It also dissolves adhesives, allowing easy removal of labels, tape and excess bonding material.
2. DISPLACES MOISTURE: Because WD-40 displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits.
3. PENETRATES: WD-40 loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts.
4. LUBRICATES: WD-40's lubricating ingredients are widely dispersed and tenaciously held to all moving parts.
5. PROTECTS: WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.

What surfaces or materials are OK to use WD-40 on?

WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40.

What about using WD-40 on my sports equipment?

WD-40 is safe and effective to use on all types of sporting goods. Use WD-40 on your bike to clean, degrease and lubricate your chain, derailleur, gears, cogs, and moving parts. It will help remove stickers. Use WD-40 to clean and protect your gun. It will prevent corrosion and it won't damage bluing. Spray it on dirt bikes to protect parts and prevent mud from sticking. Use it on watercraft to protect metal surfaces from corrosion and to drive out moisture. WD-40 is also great for cleaning golf clubs and preventing rust on hockey skate blades.

What is the propellant in WD-40?

A propellant is the stuff that helps pump WD-40 out of the can. The propellant used in WD-40 is carbon dioxide (CO2). CO2 is an inert gas which helps empty the can. Plus, the addition of CO2 reduced the number of VOCs, which helps preserve the environment. Be sure to point the spray nozzle toward the dot on the top of the can to ensure that the can fully empties.

How do I keep the red straws from getting lost?

Used for thousands of applications, WD-40 cans are now able to do something even more useful - hold onto that little red straw that was forever getting lost! The WD-40 Smart Straw® features a high-impact resistant nozzle, 360-degree valve system and permanently attached straw, so WD-40 users will never lose the straw again®. Flipped down for a wide spray or flipped up for a pinpoint stream, the WD-40 Smart Straw gives consumers a better way to spray!
For old cans of WD-40, there is the NotchCap, designed to securely hold the straw in place when not in use. Simply snap the straw into the recessed slot on the top of the new cap and it will stay there until removed. This is just another small step to keep WD-40 users smiling.

Where can I buy WD-40?

In many countries, WD-40 is available almost everywhere. WD-40 can be found in automotive, convenience, discount, drug, grocery, hardware, and home center stores. It's also available from leading distributors all over the world. If your store or distributor doesn't sell WD-40, please ask them to add it.

Does WD-40 offer sponsorship opportunities?

WD-40 Company has focused its resources on supporting athletes through Giant BMX and is no longer able to offer individual sponsorships. We wish to thank all those who have been sponsored by WD-40 Company in the past and wish you good luck in your future racing career.
 
I like pina coladas and getting caught in rain....


wd-40

Me, I love champagne and making love after midnight, but not so keen on Yoga or health food ;D

Corrosion inhibition spray is a trivial problem for a chemical engineer, its just about balancing some extra features and uses - back of the can stuff like does it clean, does stuff stick to it, does it enhance electrical contacts or is it an insulator - does it need to stick to metal, and how thick does the film need to be versus will it penetrate.

Mostly tradeoffs, but the idea that wd-40 is a secret formula is a bit amusing - its only a secret to someone who wont spend $5k for a lab to spend a few days back engineering it.. ;D actually, good chance a visit to the patent office will give you the exact formula

So if you want super long protection for a pristine motor that no dust gets near, you might choose a lanolin based product, but if you also want it to look aesthetically all clean, then you'll think lanox is rubbish for example. Horses for courses
