higher revs? it's whatever you set the screw to. Any governer you buy will have the no load rpm on it. The load limit screw is 2inch from boss to end of screw inside gov... and idle is once again whatever you want it. For setting max rpm, we just run aground into some sand at low tide. go wide open and let me adjust it. At high tide we float away
silver were just the v92. Okay engine, they tried to do one better than the 71's but it's sure hard to beat the 71 series. you don't see as many marine v92's as the longevity just wasn't there.
freight train, as long as your going unrealistically large....
My company will have a pair of 16v149's in a few months, probably pretty cheap.
or better yet, take a look at the MAK engine picture I posted in the 'big diesels' forum.
Just weld some wheels to it and sit in the V, but wear your seatbelt so the turbo doesn't suck you in.
