Reliable offers this engine to amateur constructors for use as an automotive or marine power plant. The design is of closed crankcase type with spool valves. There are no dead centered positions of the crankshaft so starting is always positive in reponse to the throttle. The design uses many commercial parts which are readily available.

The casting kit consists of 19 pieces, including cast semi-steel crankshaft, and weighs about 250 lbs. The finished engine is about 240 lbs.

Construction requires use of a 16 inch lathe, milling machine, and drill press.

* All plans are "shipped" electronically, as PDF files. If you do not have a PDF reader (software to let you look at, even print, a PDF) you can go to adobe.com (never use a PDF reader that wasn't made by adobe, the inventors of PDF), or click here: the One True Adobe PDF Reader - Download.

(Personally, we would turn off their "free offers" prior to clicking the download button [those are for non-Adobe products], but that's your call.)

BTW: "PDF" stands for Portable Document Format. It's just a secure way (the secure way, actually) to move documents around electronically.

HP (in this context) means Horse Power. (Of course you know that; just being thorough.) It's a unit of power equal to 550 foot-pounds per second or 735.5 (or 746 -- believe it not, opinions vary) watts, and is the usual measure of the amount of work an engine can do.

Oddly enough, not that closely related to the amount of work a Horse can do! (Go figure.)
See Does one horsepower really equal the power of one horse? (at www.carkeys.co.uk) for more information on that subject.
