gas mix

[jon williams]

I have a Johnson seahorse 18 hp model FD 13R, serial #963266. I would appreciate any info you guys can give me on this model. I don't know the year and what the mix should be. I would also like to know where to find parts. thanks

Re: gas mix

Welcome to Iboats, Freewilly!<br /><br />FD-13 is a 1959 18hp. As such I would use the factory recommended mix of 24:1 (1 quart of oil for 6 gallons of fuel). Use TC-w3 outboard oil and 87 octane gas.<br /><br />Plugs should be Champion J4C (replacing J4J) gapped at .030". Some people find .035" runs at low speed a little better. <br /><br />Lower unit fluid should be OMC/BRP "HiVis" or equivalent 90 weight outboard gearcase lube.<br /><br />What parts are you after? Most common consumables are available both aftermarket and from the OEM. And what isn't available from those sources is easily found in a junkyard or ebay. There's lots of support out there for that engine.

Re: gas mix

I had a 58 18hp that some guy tossed out with the trash by me a couple years ago. Froze up good. Grabbed it, and I SOLD EVERY PART ON EBAY, and made a bundle. Even the frozen block. Good motors, watch Ebay for parts.

Re: gas mix

Thanks for that valuable info. The part I need is the motor mount. The throttle handle part of it is cracked. I did check ebay and so far nothing. I'll keep looking. Thanks again.
