Hi Hennie,

 There are as many ways to specify engine weights as there are specifiers : = )  The Bare block 13B  with water pump is 180 lb.  That is the = only HARD data point that you can start with.   Only you can do the rest = of the math to arrive at your engine weight.

Here is the detail of the weight = info for my pusher 20B (265hp) installation.  The first column includes EVERYTHING (including coolant) back to the prop flange.  The right = hand column is the number that is a reasonable comparison to what Lyc = publishes for an IO 540.

These numbers are reasonably = consistent with John’s weight of 304# for the 13B when you take off the = roughly 90# for the additional rotor and the heavy center housing of the 20B; and a = couple of other things he didn’t include.
