It covers the 3 and 4 cylinder engines from 1965 through 1989 with step-by-step procedures, wiring diagrams, and real troubleshooting. Printed on paper, so it takes shop grease and stays open while your hands are busy.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSeloc manuals have been the go-to for outboard mechanics for decades, and this one covers the classic run of Mercury outboards built from 1965 through 1989. That's a long stretch of engines, and a lot of them are still running on transoms today. If you own one, restore one, or just refuse to pay shop rates for a carburetor rebuild, this is the book that walks you through it.\u003c\/p\u003e\n\u003cp\u003eInside you get the full service picture. Tune-up specs, troubleshooting charts, ignition and carburetor work, cooling and water pump impeller service, powerhead teardown, lower-unit service, and the wiring diagrams you actually need when a boat's been rewired three times by three different owners. Seloc's format leans on exploded views and step-by-step photos, so you're not guessing at the order things come apart. Torque values, gap settings, and clearances are laid out in tables you can find fast with greasy hands. It's the kind of reference you keep within arm's reach the whole time an engine is apart.\u003c\/p\u003e\n\u003cp\u003eThis one shines on the 3 and 4 cylinder engines of that era, the 40 to 115 horse workhorses that pushed a whole generation of aluminum fishing boats and runabouts. We hear from folks rebuilding a 1970s 40 horse for a tinny, and from folks bringing a barn-find 1980s powerhead back to life. Both crowds get what they need here. It's especially strong on the older 2-stroke carburetor and breaker-point ignition work, which is exactly where the pre-1976 motors tend to give people trouble. Get the mixture and timing right on one of these and it'll run for years, and this is the reference that gets you there.\u003c\/p\u003e\n\u003cp\u003eWhy bother with a manual at all when there are forum threads and videos? Because a good manual gives you the numbers. The right plug gap, the right idle mixture, the torque sequence on a powerhead so you don't warp a head. Forum advice is great until two people disagree and you're left guessing. This book puts the service values in one place, organized by system, so you can work through a job start to finish without twenty browser tabs open.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. The manual is thinnest on the very latest model years. Some of the 1986 to 1989 wiring changes and later electronic ignition setups aren't covered in the depth the earlier stuff is, so if you're deep into a late-80s engine it's worth cross-referencing a factory service bulletin for the specifics. Lower-unit seal detail is a bit lighter than the powerhead coverage too. For most owners doing tune-ups, carb work, and top-end rebuilds, none of that will slow you down.\u003c\/p\u003e\n\u003cp\u003eIt's a paper manual, and that's a feature at the workbench. It stays open, it doesn't need a charged battery, and you can prop it against the cowling while you work. One tip from the crew: the binding takes a beating in a busy shop, so if this is going to live on a greasy bench all season, scan the pages you use most and keep the original clean. Treat it right and it'll outlast the project.\u003c\/p\u003e\n\u003cp\u003eNot sure it fits your motor? The quickest way to check is your engine's horsepower and year. This edition is built around the 3 and 4 cylinder Mercury outboards of the 1965 to 1989 span. If your motor falls in that range, you're in the right place. If you've got a big V6 or a very early single, give us a shout and we'll point you to the correct Seloc coverage.\u003c\/p\u003e\n\u003cp\u003eBottom line, if you're wrenching on a 1965 to 1989 Mercury outboard, this Seloc manual pays for itself the first time it saves you a trip to the dealer. We stock it, and we're happy to confirm it's the right coverage for your exact engine before you buy.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eCovers Mercury outboards from 1965 to 1989, so one book handles a wide range of older motors\u003c\/li\u003e\n  \u003cli\u003eFocused on the 3 and 4 cylinder engines, the 40 to 115 horse workhorses of that era\u003c\/li\u003e\n  \u003cli\u003eStep-by-step procedures with exploded views, so you know the order parts come apart and go back together\u003c\/li\u003e\n  \u003cli\u003eWiring diagrams included for tracing circuits on boats that have been rewired over the years\u003c\/li\u003e\n  \u003cli\u003eTune-up specs, gap settings, and torque values laid out in quick-reference tables\u003c\/li\u003e\n  \u003cli\u003eStrong coverage of 2-stroke carburetor and breaker-point ignition service on the earlier models\u003c\/li\u003e\n  \u003cli\u003eTroubleshooting charts to diagnose running problems before you start pulling parts\u003c\/li\u003e\n  \u003cli\u003ePaper format that stays open on the bench and needs no battery or screen\u003c\/li\u003e\n  \u003cli\u003ePrinted in English by Seloc, the long-trusted name in outboard service manuals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sierra Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat years and engines does this manual cover?\u003c\/summary\u003e\n    \u003cp\u003eIt covers Mercury outboards built from 1965 through 1989, centered on the 3 and 4 cylinder models in the 40 to 115 horsepower range.
