What do ya'll use on the powerhead for corrosion protection? Corrosion-X is gettin' a little pricey. Are there many alternatives? Something safe for electrical, paint and hoses?
Use a pure silicone spray for best results. <br /><br />An oil base spray like WD 40 will affect the wiring, hoses, and rubber parts after a while. I've seen spark plug wires swollen up like sausages from too much "protection".<br /><br />A sticky or oily coating will also attract and hold dirt and grime.
Interesting topic...It may be different now but in past years there were warnings on silicone sprays about them attacking plastics. I used silicone and teflon sprays on motorcycles (because it was dry and didn't collect dirt) a long time ago but never had bikes long enough to see damage. <br /><br />I started using CRC on ob motors after speaking with their factory techs. According to them, 2-26 is a light mineral oil and it doesn't harm plastics like WD40 and their own CRC 6-56 can (they say DO NOT use their 6-56 on rubber as seen in use at many marine stores). I have two motors purchased new to benchmark against with 2-26...1991 & 1996. Since new, both get a full flood coat of 2-26 annually. They are saltwater motors and still look almost showroom condition under the hood. Both are still 100% original and none of the wires/plastic is brittle or dried out like WD40 types do. The mineral oil dries to a non sticky film and dirt collection doesn't happen. I use one can per motor from powerhead to tip of skeg and get them dripping wet.
