One printed volume, written for the person actually turning the wrenches, with step-by-step procedures, wiring diagrams, and real photos. If you're keeping an older two-stroke running, it belongs on your bench.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're keeping an older Johnson or Evinrude outboard running, this is the book that lives on your bench. It's the Seloc manual covering Johnson and Evinrude outboard engines built from 1971 all the way through 1989. One volume, English, printed on paper so you can flip to a page with greasy hands and prop it open next to the powerhead.\u003c\/p\u003e\n\u003cp\u003eSeloc manuals earned their reputation the honest way, by being written for the person actually turning the wrenches. You get step-by-step procedures, exploded views, and real photos, not a wall of theory. Whether you're doing a seasonal tune-up on a 9.9 portable or splitting into a bigger V4, the sequence is laid out so you know what comes off first and what the numbers should read when you put it back together.\u003c\/p\u003e\n\u003cp\u003eThe 1971 to 1989 span is a wide one, and it's a good chunk of the outboards still working lakes and bays today. Small portables in the 2 to 15 horse range, the popular mid-size 25, 35, and 40 horse motors, the 70 and 75 three-cylinders, and the bigger V4 and V6 powerheads. The manual groups the procedures by system and by engine family, so once you know your model and year you can jump straight to the section that applies without wading through motors you don't own.\u003c\/p\u003e\n\u003cp\u003eBeyond the big repairs, the routine maintenance chapters are what most owners open the most. Water pump and impeller replacement, spark plug and gap specs, gear oil changes, fuel filter service, and the seasonal winterizing and spring commissioning steps are all spelled out with the intervals these motors were built around. Stay on that schedule and one of these outboards will outlast the boat it's bolted to. Skip it, and you'll meet the troubleshooting chapters a lot sooner than you'd like.\u003c\/p\u003e\n\u003cp\u003eThe electrical coverage is where a lot of owners get their money back. There are wiring diagrams to trace a no-spark problem, and the ignition sections walk you through testing so you're not just throwing parts at it. Pair the book with a decent multimeter and you can chase down most starting and running faults on the older two-strokes without a trip to the shop. A common job on these motors, a 115 that won't fire, becomes a methodical checklist instead of a guess.\u003c\/p\u003e\n\u003cp\u003eFuel and carburetor work is covered thoroughly. Rebuild steps, jet and float settings, and carburetor synchronization on the multi-cylinder motors are all in here, which matters because a rough-idling 70 three-cylinder is almost always a sync or a dirty carb. Down low, the lower unit sections cover gearcase service and seal replacement, the kind of work that keeps water out of your gear oil on the 25 to 40 horse motors that see the most abuse.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anybody maintaining a 1971 to 1989 Johnson or Evinrude, from the weekend owner doing plugs and impellers to the shop tech who wants torque specs and timing values in one place. It's an aftermarket service manual, so for a few of the late-1980s loop-charged and oil-injection updates you'll want to cross-check against your OEM parts fiche. That's normal for any manual of this era, and it's honest to say so up front.\u003c\/p\u003e\n\u003cp\u003eOne tip from the crew. Paper soaks up oil fast when it's riding around in a bilge or an open toolbox, so a lot of owners tuck it in a zip bag or laminate the pages they use most. Treat the spine kindly on the first few opens and it'll ride out years of spring commissioning. For the money, it's the reference that pays for itself the first time it saves you a shop visit. And on a motor this age, parts and know-how are half the battle, so having the right procedure in front of you keeps a small job from turning into a big one. Keep it on the shelf next to your torque wrench and it'll earn its spot.\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 outboard engines from 1971 through 1989 in one volume\u003c\/li\u003e\n  \u003cli\u003eStep-by-step repair procedures with exploded views and real photos, not just theory\u003c\/li\u003e\n  \u003cli\u003eWiring diagrams for tracing no-spark and electrical faults with a multimeter\u003c\/li\u003e\n  \u003cli\u003eCarburetor rebuild, jet and float settings, and multi-cylinder carb synchronization\u003c\/li\u003e\n  \u003cli\u003eLower unit and gearcase service including seal replacement\u003c\/li\u003e\n  \u003cli\u003eIgnition testing and timing procedures for the older two-strokes\u003c\/li\u003e\n  \u003cli\u003eRoutine maintenance coverage: water pump, impeller, plugs, gear oil, winterizing\u003c\/li\u003e\n  \u003cli\u003eTorque specifications and factory service intervals in one reference\u003c\/li\u003e\n  \u003cli\u003eEnglish-language paper format sized for the workbench\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 does this manual cover?\u003c\/summary\u003e\n    \u003cp\u003eIt covers Johnson and Evinrude outboard motors built from 1971 through 1989, from the small 2 to 15 horse portables up through the 25 to 40 horse mid-size motors, the 70 and 75 three-cylinders, and the larger V4 and V6 powerheads.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this a printed manual or a digital download?\u003c\/summary\u003e\n    \u003cp\u003eIt's a printed paper manual in English.
