Nope, that's weight of engine and required systems (cooling, redrive, alternator & starter).
. Trying to define it in the same way that Lycoming defines their engine weight for comparison purposes. eng mount, brackets, ducts, prop, mounting hardware, exhaust system, etc must be added for FWF weight.

Hi Dwayne, I estimate I'm getting about 200 HP at 7200 rpm on the Renesis. 230 is probably the best you are likely to get when normally aspirated and then you will need to turn it a bit faster. I went all out for weight reduction on my RV-4 so the engine & systems came out around 260 lbs.
OTOH, I'm getting about 270 effortless HP from the 20B at 6250 rpm. Should get 300 if turned to 7000. This install weighs about 90 pounds more than the Renesis though. Tracy
