Hello there Westcoaster,
Your FR2 looks fairly complete, and as long as it has the injection gear undamaged, it's a good chance it could be salvaged. Their design
postdates the CS types and they are one robust engine. They were only in production for 9 or 10 years from mid 1950's I think, and were discontinued when the new
aircooled series proved more popular,(and possibly cheaper to make). Being totally enclosed and self lubricating, they were a great marine engine. I hope to find one
someday, but they seem thin on the ground here in Australia. Spares can be a problem, as I don't think the Indians built anything equivalent. If you are keen on
rebuilding or restoring, grab it with both hands, or pass it on to someone who will give it the attention it deserves, Regards, Combustor.
