This is my latest attempt at more thrust. It is a 440cc liquid cooled two
stroke snowmobile engine capable of producing about 55hp with a redline of about 7000rpm. The fan is geared to turn
at 3000rpm max. The engine has lots of compression. It only has a pull starter right now but if it proves itself to be a good
engine, It will get an electric starter.

The exhaust fit really well. It has lots of room for heat dissipation too.
I have a 2" tailpipe on it that puts the exhaust gases out past the thrust duct.
The electric fuel pump is to help the lift engine. Both engines have mechanical
fuel pumps.
