Hi!

Does anyone know real HP for

VRod 400 comsumer model (2020)
Vrod 400R
Merc 450R

I hear that NorTech has experienced loss in speed with the new Vrod 400 over the Vrod 400R.

Thanks :)

Cheeers, Toffen

Excuse my ignorance but what is the advantage of a twin 400hp outboard vs twin 400 hp I/O. With that mild power engine shouldn't engine life, performance and maintenance be similar. I dont understand outboards for everything?

The new OB engines are designed with much newer/better technology. Your old 502 mpi had pushrod valve train instead of a overhead cam system is just one of the 100's of major differences between the two. Your not going to see your 502 mpi last 2000 hrs yet the outboards are doing that.

.... and they're running at all rpm's in low decibels and sipping fuel vs. the I/o counterparts.

The big o/b's are in the 2010's (to date) what the 525 was just prior to the Outboard domination trend took off in the boating market,

I wouldn't say the 525 was, that thing is still based on the replacement for the W motor of the early 60's.

The LS based motors are at least closer but no one uses them in a performance boat.

That said the new 300R at 4.6 Liter and 300HP has to be one under stressed motor. But at the price tags of these things they should be reliable, just wish there were more performance V's being built.

I was just referring to the period of time when the market trend was to have the 525 blue motor otherwise it was considered not enough power to envy or you needed to be on a first name basis with your mechanic as you were breaking parts and/or drives.

No different than a merc blue engine will resell a boat faster than alternative brands - its the perception of being more reliable until the next trend in superior technology spanks the Verado.

MPIs can last a long time. Not a ton of outboards doing 2k hrs that I’ve seen. Unless it’s a daily type of operation. Pleasure boaters roll the hours up slower.

I will say my 454 MPIs sound 10x better than my Suzuki V6s. The OBs are quiet at low speed though. I hope Mercs V8s sound better, I’d like to have a set but need to see what reputation they get first.
