WAY TO GO,12FOOTER. DON'T EVER LOOK UP WHEN YOU'RE PECKIN KEYS!!! I meant "Saltwater -Cooled engines"....<br /><br />About a year ago, I went fishing. I didn't catch anything,but found two submerged motors. I went back and picked them up. THey werent worth much,but did have some salvagelable parts. I had one of them in a wheel barrow,awaiting teardown,and decided to spray some WD40 all over it (to start the bolt loosening process). I went back there two days later to spray some more on it, and to my amazement, the stuff ATE the aluminum oxides off the motor's surface.<br />I removed the head and exaust port plate, and found out why they tossed these engines.<br />The water curcuit was completely plugged with oxides and cryltalized salt. I sprayed some 40 all over the manifold area....<br />Again,to my suprise, it devoured this stuff to the metal!!!!<br />I mention all of this in an effort to assist all of my salt water bretheren out there with a port plugging problem. Every time I come back from slatwater, I flush the engine, then I remove the T-stat. I then duct tape over the water pickup,and spray WD40 into the housing until it backs up. I let it sit for about an hour,then remove the tape. After doing this for the entire summer, it came time for my anual impeller change-out (done whether it needs it or not).<br />I removed the exaust port plate also, to examine the buildup..None! Not only that, but the surfaces were coated with what looked like clearcoat. I really think it works better than Salt-X, but then,I've never used Salt-X. It's too expensive. But treating my engine with WD40 figures-out to an average cost of 50cents per trip (half can).<br />Just thought you'd like to know, and no, I don't own WD40 stock. but when I find something that works, I pass it on.
