You can find a shop manual for your engine on the internet. That's the first thing you should buy. One place that has them is marineengine.com.<br /><br />Libraries often have copies of the Seloc or Clymer manuals that cover these old engines as well.<br /><br />Also, do a search on this forum. Those 10 hp QD models are quite popular and there are quite a few message threads on them here.

Howdy, Savage.<br /><br />Welcome to iboats. <br /><br />You came to the right place.<br /><br />QD-15 (1954): BoreXstroke 2-3/8"X 1-7/8". <br />16.6 Cubic inch twin cylinder.<br />10HP @ 4000rpm<br /><br />Double mageneto ignition. Point gap .020"<br />Champion J6C (replaced J6J) spark plugs gapped at .030".<br /><br />Fuel mix: 24:1, 87 octane unleaded gas and TC-W3 rated outboard oil. One quart oil to a six gallon tank of gas. Uses pressure tank system, no fuel pump.<br /><br />Weight: 60lb.<br /><br />Very good little engines that are smooth running and easy to work on. Very torquey at low rpm/trolling speeds.<br /><br />Aftermarket manuals here: http://www.boatmotors.com/manuals.html <br /><br />marineengine.com (mentioned by CAT) and kencook.com have reprints of the original OEM Manuals, which I recommend, or you might find one on ebay.<br /><br />You can find some parts here: http://www.boatmotors.com/parts/ <br /><br />Parts can also be ordered from your JohnnyRude dealer or a NAPA store.<br /><br /><br />Treat her well, she is a winner.
