New CAT engines

CAT came out with an engine to rival the 16v2000's with the proper weight and size a while back. They built and tested like 6 sets. They asked the heavy machinery division if they could use it, the generator division, they said no. It never got approved, so the project was canned.

They are going to produce the motor in 2000, 2200 and 2400 hp versions. The larger hp will have sequential turbos. Supposedly will be ready for installs in January.
The up graded motors cat was going to produce a few years back were on the trucks ready to deliver when they pulled the plug. They really hurt a few builds waiting for them. Yes construction dictates the motors they build, marine is just a tiny fraction the size.

One of the new builds I think had them installed when they pulled the plug, for a large CAT dealer.

All the engine manufacturers have larger for construction or commercial, just a matter of tuning for yachts and also just the physical size issue.

No the larger are too heavy for the HP output, so only suited to displacement yachts (mega yachts). CAT came out with a motor above C32, that was compact and light weight, but since the marine industry (yachts) comprises 5% of their sales, and nobody cares about weight in an earth mover, it never got passed.

Yes same package as c32 with additional turbo. The 2025 is same dimensions as current, drop in ready. The 2200 and 2400 are dimensionally larger but don't know exactly how big. Spencer and scarbrough are each building a new boat specially for these new motors.

I would think it would be similar to other manufacturers in those horsepower ranges.

Makes one wonder if, while they were at that, they also thought to fit some half decent intercoolers...

so cat launched the C32B at 2025HP...is 2200 and 2400 hp coming later?

Yes, supposedly.

Interesting to hear that...

"Sea water system is electrically bonded, so there is no longer zinc anodes to replace."

I always wondered why they never followed the route the Germans took 30+years ago.
It's a bit disappointing to hear now that they simply needed so much time to learn.
Maybe they should have moved engines design to PRC, to speed up development...

I just wonder if they're as noisy or worse than the rest of the line.

No, they are supposedly much better. Multiple injections of fuel per cycle to help with noise per cat rep up to 1200 rpm.

Triple turbo's? Sounds like a lot of boost crammed into the same engine.

2400 has triple turbos, yes is alot of power from that block.
