what are the engine's dimentions?

[tunneltug]

Hi, I tried to reply earlier but for some reason it doesn't seem to have worked. The dimensions are 4.5" + 7.0" x 7.5" running on 150psi at 250rpm gives 15bhp

Very nice. How is the boat geting on?

Hi Daniel, The boat build is due to start in March 2010 but you know how these things seem to be very flexible. If all goes well it should be in steam by autumn of that year.

@tunneltug 5252*15bhp/250 rpm = 315 lb-ft of torque! thats gonna swing a giant oversquare!

@savedfromscrap Thanks for the comment, the boat hull build should start later this month and take about six months. I will start dismantling the engine soon ready for installation.
