It's the shop-bench reference for tune-ups, carb rebuilds, lower unit work, and troubleshooting on those older two-strokes. English, paper format, written for the boater actually doing the work.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSierra's 18-01308 is the Seloc repair manual covering Johnson and Evinrude outboard motors built between 1973 and 1991. That's nearly two decades of two-stroke powerheads in one book, from the little kickers up through the mid-range motors that pushed a whole generation of fishing boats. Inside you get step-by-step repair procedures, exploded diagrams, maintenance schedules, tune-up specs, and troubleshooting charts written for the person actually turning the wrenches.\u003c\/p\u003e\n\u003cp\u003eThis is a bench manual, plain and simple. If you keep an older Johnson or Evinrude running yourself, it walks you through the jobs you'll actually face over a season. Carburetor rebuilds, ignition timing, water pump and impeller service, lower unit work, and the tune-up steps that keep an old two-stroke starting on the first or second pull. It's the reference you reach for before you pull a powerhead, not after.\u003c\/p\u003e\n\u003cp\u003eWhat sets a full service manual apart from a quick reference card is the depth. You get exploded views that show how every part stacks together, so when you've got a lower unit apart on the bench you can see exactly what order the shims, seals, and bearings go back in. There are torque values for the fasteners that matter, gap and timing figures for the ignition, and clearance specs for the powerhead. For a decades-old motor with no dealer support left, that kind of detail is the difference between a clean rebuild and a box of leftover parts.\u003c\/p\u003e\n\u003cp\u003eIt fits some motors better than others. Owners tell us it's strongest on the 1973 to 1985 range, especially the 9.9 and 15 horse motors you'll find on dinghies and tiller-handle fishing boats, and the 35 to 70 horse mid-range engines. The carb and ignition timing sections for those 1970s motors are detailed and easy to follow. If you're doing a full top-end job, pair the manual with a compression tester and a carb sync tool and you'll have what you need to work through it methodically.\u003c\/p\u003e\n\u003cp\u003eWe'll be straight with you about the limits, because that's how we'd want it. The manual is thinner on the later 1989 and up V4 crankcase seal work, and it doesn't carry full wiring diagrams for the 1990 to 1991 models with optical ignition. For those, cross-reference the factory service bulletins. A few torque specs on lower unit work aren't spelled out either, so keep a factory parts catalog handy for the final numbers. And if you're running a big 150 horse and up V6 powerhead, this book covers it but doesn't go as deep as it does on the smaller motors.\u003c\/p\u003e\n\u003cp\u003eOne practical note from the shop. It's paper, and two-stroke oil and gas will soak into paper and tear it fast once your hands are dirty. Slide the pages you use most into a plastic sleeve, or laminate them, and the book will last for years on the bench. The photos run a little low on contrast too, so a good work light helps when you're trying to pick out a small part in a diagram.\u003c\/p\u003e\n\u003cp\u003eThink of it as part of your winter routine too. Come haul-out, the maintenance section walks you through fogging the cylinders, servicing the water pump, changing the lower unit oil, and stabilizing the fuel system so the motor fires up cleanly in spring. Do that every year and an old Johnson or Evinrude will outlast boats twice its age.\u003c\/p\u003e\n\u003cp\u003eBottom line, if you own an older Johnson or Evinrude and you'd rather fix it than pay someone else to, this is cheap insurance against a bad weekend. Sierra distributes the Seloc manual as their standard shop reference for these legacy outboards, and for the money it pays for itself the first time it saves you a trip to the mechanic.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eCovers Johnson and Evinrude outboards from 1973 to 1991, nearly two decades of two-stroke motors in one book\u003c\/li\u003e\n  \u003cli\u003eStep-by-step repair procedures with exploded diagrams for carb rebuilds, powerhead work, and lower unit service\u003c\/li\u003e\n  \u003cli\u003eTune-up and ignition timing specs for the 1970s 35 to 70 horse models, so you can dial it in without guessing\u003c\/li\u003e\n  \u003cli\u003eTroubleshooting charts for hard-starting, no-spark, and running issues on older two-strokes\u003c\/li\u003e\n  \u003cli\u003eMaintenance and winterizing sections covering water pump service, fogging, and fuel stabilization\u003c\/li\u003e\n  \u003cli\u003ePaper format, English, sized to live on the bench next to the motor\u003c\/li\u003e\n  \u003cli\u003eSeloc-authored reference distributed by Sierra Marine, the standard shop manual for legacy outboards\u003c\/li\u003e\n  \u003cli\u003eBest matched to 9.9, 15, and 35 to 70 horse motors on tiller-handle fishing boats and dinghies\u003c\/li\u003e\n  \u003cli\u003ePairs with a compression tester and carb sync tool for a complete top-end job\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 engines and years does this manual cover?\u003c\/summary\u003e\n    \u003cp\u003eJohnson and Evinrude outboard motors built from 1973 through 1991.
