My grandfather just gave me his Johnson FD-22a, # j2892874. I am not finding much on the net about an fd-22a, and hope someone may be able to tell me what year, hp, mix ratio, and book I should get to maintain it.<br /><br />THANKS!

Re: Grandfather's motor - help!

Welcome to Iboats, etarbox. You came to the right place.<br />Johnson Model FD-22<br />Year: 1968<br />HP: 20<br />WOT RPMS: 4500<br />Displacement: 22.0 cu.in. = 360.5 ccm<br />Cylinders: 2<br />Weight: 79 - 81 lbs. = 35.8 - 36.7 Kg <br />Gear Ratio: 12:21<br />Spark plugs: Champion J4C gapped at .030"<br />Fuel/oil mix: 50:1 87 octane gas to TCW-3 rated outboard oil.<br />Lower unit oil: Bombardier 'HiVis' or common 90W outboard motor gear oil.<br /> Picture<br />From the Old OMC Site<br /><br />Iboats sells aftermarket, generic repair manuals which cover your engine. And the one they sell that covers your engine is not bad at all (Seloc I). Likely, you'll find them also at your local libary. The superior manual is the original OMC factory service manual, which are still reprinted. Here's a few suppliers:<br />TheOutboardWizard<br />Mastertech<br />Marine Engine<br />Ken Cook <br />If the engine's been sitting unused for some time, you'll want to change out the water pump impeller at least. Parts are available and inexpensive.

Welcome to iboats.<br /><br />Congradulations on your acquisition of a 1968 20Hp Johnson. Good motors, still plenty of them in service. Premix is 50:1, points gap is .020", Champion J4C gap is .030". Plenty of parts still available to keep that classic purring. There are a few aftermarket manuals available. Try Ken Cook for factory manuals.
