I have read that a good maintenance practice is spraying engines twice a year with silicone / T9. Is this a practice that some of you are doing? If so, are you spraying entire engine ( hoses/ belts?? etc.)
Thanks for the feedback

I spray mine, but with what every I happen to have, WD-40, CRC, silicon, just about any oil... I aviod spraying the belts... I spay each each when I winterize, and other times when I happend to have a can in my hand...
 
I've used WD-40 in the past. Boeshield is great, I just have not used it on my engine yet.
 
The best application I found was corrosion block. It's $20 for a small buttle, but it works great. You can see the nice sealer coating that stays on the engine for a long time. I spray my engines and genny with it when I winterize the boat. I've used T9 but it doesn't last that long as the coating is much thinner. I think it's good for mid season treatment (at least that's how I used it).
 
I spray mine down with Corrsion Block also. You can get it at WM but it's not cheap. Since I boat in saltwater I do what I can to keep things from corroding.
 
Depends on where you boat. You don't need to spray if your boat on the Great Lakes. How salty is the Chesapeake Bay?
 
The salinity of the chesapeake depends upon the area. I boat in the middle and mostly upper bay-- which is brakish.
If silicone is used will it harm the belts or allow them to slip?

I spray my engine down lightly with 6-56 after evvery run. Prob a little overkill, but it is salt water. I buy it by the gallon and put in into a garden sprayer. This way I can use the wand and get the oil pan. The last thing that I want to do is pull an engine just to change out a rusted oil pan!
 
I use a little wobbly D40 a couple o times a year. It really keeps the surface rust at bay. I,m sure there are lots of other products out there that are good too, I just seem to always have it on hand.
 
I have touched up some areas of my engine that were showing some rust with black Tremclad Rust Paint using a small hobby brush. Being in the Great Lakes, there isn't that much rust to worry about, but if there is constant moisture from a leak - rust will still happen!

I've never had enough of a problem to spray with silicone.

He boats on the great lakes. No salt, no rust except where he turns a wrench. People up here do not spray.
 
Somewhat along this thread. We have sprayed ours engines with CRC 656 per MarineMax advice, but not very often. I keep the bilge dry as a bone which helps and touch up any rust spots to HT Rustoleum.

Any of the engine sprays tend to be oily or sticky, so what do you use to clean your engines from the eventual dirt and grime build up?
 
I spray WD-40 on all the exposed screws, clamps, and bolt/nuts not just on the engine, but on the outdrive, swim platform, and trailer after every run.
 
Been using CRC for the past 5 years no rust .I us a pump up garden sprayer,buy it by the gal. that way you can spray under the eng. ...Rip
 
Long away and far ago on my first boat....WD 40 all over the engine when winterizing. This was in R.I. boating in Narragansett Bay. I got the external rust at bay the first season. WD40 was a cheap preventive year to year maintenance procedure for 5 years.

I need to get back into this as I am seeing some surface rust in Saint Max' engines despite the fact I am in highly fresh water brackish water.

My 2 cents.
