I don't know about internal parasitic losses, but I have a few external ones: Inland Revenue, Council Tax to name but two.... oh and offsprings. Friction........................... I will leave it to the younger members (no pun intended) to discuss frictional losses. Young engines/boaters have more frictional losses? windage in the crankcase.............. Ah that is something I can understand. I usually say *pardon me*. Phil ------------------------ Yahoo! Groups Sponsor --------------------~--> Great things are happening at Yahoo! Groups.
