Re: OMC ZEPHYR SAILDRIVE motor model 15S10S
Welcome to Iboats!<br /><br />I think the only thing that covers those is the original factory manuals. They're a bit pricey but they're by far the best. You can get reprints from kencook.com, marineengine.com, theoutboardwizard.bizhosting.com, and maxrules.com. I belive they're essentially a normal Johnson/Evinrude 15hp block mounted on the Seadrive leg.<br />I don't see any used ones on ebay.
