Pair of Diesels Wanted

[Latestarter1]

I really appreciate your thoughts, guys!

Funnily enough, I was thinking about a pair of Sabre 370s. They're coming with 1:1 gearboxes, rather than my existing 2:1 (or maybe 2.5:1 - I haven't got the details in front of me). As I'll be doubling the horsepower, then surely it would make sense to keep the 1:1 'boxes. The shafts are 1 3/4" thick, and the p-brackets very meaty (they're steel so additional beefing-up shouldn't be too difficult if that's needed). Then the props should simply be turned through the water twice as fast... I know it's not that straightforward... but...

Thanks for the heads-up on the Sabre 370s, by the way. I had no idea they used so many bespoke Sabre parts: I thought it was just a case of cooling the air down as much as possible and using a bigger turbocharger. After all, what else is there to fiddle with - other than cylinder-head porting - really just to get as much oxygen in as possible, as quickly as possible.

I wonder what existing Sabre 370 owners do for parts, or have they just all written theirs off and they'll keep on using them until they die and then repower? I might just pose the question on here to see what people are doing about that...

If engines are with 1:1 72C's likely came from Fairey Spearfish 'Growler'. Owner spent $$ with upgraded pressure relief valves and different clutch plates from U.S, none of it worked. Subsequent owner did sensible thing and ripped engines and boxes out and started again.

What do owners of these engines do? Have sleepless nights. Quite a few were used in Nelson 45's. There is an immaculate 45 around with an very well maintained pair, retired owner put vessel on the market and was horrified when he discovered that his pride and joy could only attact value of a repower project...

Sabre used 115 mm cranks from Ford GB and 112 mm pistons from big 7.7 out of Ford Brazil and had their own block cast for the 370. All ended in tears, Ford shifted Dover production to Otosan of Turkey and shut their Brazil operation completely cutting supply of 7.7 stuff. Ford then sourced B & C engines from Cummins for Ford trucks.

CAT purchased Sabre Engines shortly after buying out Perkins. Spares for EVERYTHING other than plain vanilla Dover 212/225's went to the scrap man.......................

That's that idea out of the window, then! I can't tell you how much your wise words are appreciated. I think I'm veering back towards just having both the existing engines rebuilt. On the subject of which, YHM!
