Wait, so they are claiming a 450hp tune of the 400R without a dyno pull to confirm? Interesting...

How can anyone offer a new tune for a motor and claim any HP gains without testing on a dyno? All re-flashes should be analysed on a dyno including analyzing air fuel ratio, engine temp, EGT, exhaust gas composition, etc.

My prediction is a sub 400lb 250 or 300HP N/A racing motor loosely based on a current production powerhead, with DOHC and 4 or 5 valves per cylinder and NORMAL rigging, in 12, 15, and 20" versions. The Verado platform is mature and was never geared toward high perf use as most of us know it, they need a clean slate based on another production motor to keep the costs in check.

Furthermore, most people bitching and whining about the demise of the "lightweight" motors will still bitch and whine because 90% are broke dick boaters who were running 20+ year old cobbled together fishing motors and have never bought a new Merc Racing 2.5 even when they were available. The mainstream guys who actually bought new 2.5 drags and 280s will eventually start repowering and the early adopters will be all over them.

But why listen to me? I'm just a poor, dumb, cad guy.

I'm just waiting for a clapped out chinese 60 hp to come around cheap so I can slap a turbo on it and satisfy my sadistic curiosity of when

happens.

After taking inventory of my old sh*tty obsolete racing motor hoard yesterday and I'm good for quite a few years. Still a few unopened cardboard boxes with big long part numbers on the stickers.

Surely someone has tried the reflash, and could share the results???

I would not bet on it. The way 400r's are selling it may be longer than that! We can only hope.

**KakaroT** · 05-18-2018, 12:12 PM

For sure they gona supercharge that unit soon

Each major marine show has had rumors of a 450 or 500 HP Verado and each has was met with denials from Merc racing. Eventually increases will happen but nothing official to affect buying decisions.

They just need to amortize their 400R expenses first and then the fun begins with the new V8s.

**fatherb68** · 08-01-2018, 09:51 PM

I have heard there already is a 525 based on the v8. They have tested it and cant keep a gear case on it. That what I heard from someone in Florida.

Sounds like fake news to me. Looking forward to the future-

Remember the v8 hyabusa tested to try and be a f1 replacment and the other v6 4stroke..
High teving multivalve 4s, cant compete unless boosted or needs multispeed gearboxes

I wouldn't be surprised if an automobile supercharger guru is already working on supercharging the latest 300R V8 from Merc as an after market product

300R Seems like a good platform to be done on
