Wards Sea King Oil

[Kenny Sorweide]

I have a Wards Sea King 7.5hp With Clinton motor.<br />Year--????<br />Model# K7515106B<br />Serial# 1511084<br />Type# XTV50575B<br />On the front it says to mix 3oz of SAE 30 OIL per gallon of gas. Can this mean just plain auto oil? If so will both Detergent and non-detergent work. I know that members of the forum have said to use a chain saw type oil. I'm probley wrong but doesn't this figure out to 42.66 to 1 mixture? The guy I got it from said he thought it had 50 to 1 outboard mix in it. It runs good on that, but I know doing that is a no-no.<br />Also what is the proper plug to use? <br />Thanks for any input

Don't use chain saw oil. Use TCW-3 instead, just as the stocker says 3 oz per gallon. A little extra now and then doesn't hurt...if your hand slips.

I disagree with Tim!<br /><br />Air cooled engines operate at higher temps than water cooled engines. That is why there is a "W" in TC-W3, to specify "Water cooled".<br /><br />When Kenny's engine was produced, there were no specialty 2 stroke oils available, and non-detergent motor oil was common, though it produced a lot of coking (carbon). Detergent oil is much worse.<br /><br />Use chainsaw or weedwhacker oil, Kenny. It is made for air cooled 2 stroke engines. The 42:1 ratio recommended is fine for that engine. Do not use 50:1 with TC-W3. It will drastically shorten the life of the engine.<br /><br />Good luck.

Sea King KTV50575 is a 1979 7.5hp engine. XTV doesn't make sense - could that X be a K?<br />Champion now suggests RJ14YC, gapped at .025"

Re: Wards Sea King Oil

Thanks guys. I have some weed wacker oil that I can use in it. Glad I got the info about SAE 30 oil causing carbon. I don't have any idea what I am going to use this motor for, as it came on a boat that I will use an electric trolling motor on. Gonna be a lot of fun playing with it anyway. Thanks again for the info.
