Out of nothing but curiosity, does anybody know what blocks were in there for sure?

I respect the hell out of FB. The man has always been an innovative thinker and into running REAL OFFSHORE RACING, rather than some of the 1 or 2 boat field "World Championship" pond racing often found in the US in recent years.

After 15 minutes of frustrated Googling this is all I could find;

'THE series 1700 engine is available in the 700 to 2600kW output range. It is used to power new shunters or to re-power existing locomotives. The series 1300 (pictured right), which until now has been used for marine, road vehicle, and industrial applications, covers the 220 to 880kW output range. It is available in three versions: as a six cylinder in-line engine, and in a V configuration in either eight or 12-cylinder versions.

The six-cylinder in-line engine is the first series 1300 unit to be adapted for rail. This is an 11.3 litre engine with a 130mm bore and a 142mm stroke.'


So the 8 and 12cyl versions will be even larger...

fantastic I see you are doing plenty of research on the post I made in ... Best rough water boat ever built?????

Big ones

I knew about that boat years ago, just forgot it. When you have a vessel that can run 110mph in 8-10s all day you know you are almost unbeatable.

Taking a lecture last year from FB at Cowes!

Isotta F 1312-engines, V12 - 20 liters.

You're a lucky man to get face time with the Maestro...

hey get back to your side of the pond by the startled look on your face I recon Buzzi just told you how much HP those diesel's really make

At 1.07 HP/Cubic Inch, that's pretty mild. I wonder what those things weigh?
