Volvo D6 350hp & DP-R drive

Any experience or thoughts about this combination ?
I have currently an E-TEC 250H.O. on my boat and no experience at all with diesel boats .
While the Yanmar has the reputation being bullet proof but suffers from turbo lag - what about the Volvo ?
It's been on the market already quite a while .
Any issues with hardware ?
Electronics ?
What about the DP-R drive ?

"the Yanmar"?

A specific Yanmar or all of them?

The 315hp 6LP is notorious for turbo lag - I wouldn't give the steam off my p1ss for a 6LP. The 8LV is a different story entirely

Yes - "the" Yanmar with 315hp ..
I know a few people having boats with this motor but I don't know anything about the Volvo D6 350 .
Will have a look at 2 boats - 1 comes with 6PL - the other one with D6 ..

You don't need a computer to fix a 6lp!!

The modern D6 Volvos and the v8 Yanmar are both good engines Jurgen
I think that the Volvos seem to have a better reputation with the out drives the New Yanmar drive has been a bit temperamental.the other issue is dealers. volvos have a lot more

Mike , I regret that I never jumped on Fast Forward to "feel" the 6LP ..
Non existing electronics would have saved my Corsica cruise in September .. ))
The Volvo I mean is the older D6 350 common rail .
In addition to the turbo it has a compressor which helps to overcome the turbo lag .
Hope somebody here has one and can comment .

I can't comment on the Volvo, but I love my 6LP, and the simplicity of it as commented above! Yes it has a bit of turbo lag, but I've never had any particular issues due to that. I certainly wouldn't completely discount a RIB with a 6LP before you've given one a decent test.

Donít know the 350, only the 330 and 370.
Both donít have the compressor.
Bulletproof engines and more snappy than the yanmar.
Pain in the .... to repair $$$ you need a dealer with vdo computer to do anything.
A lot is replaceble but ďifĒ your cilinders are worn, you need a new bare block (donít know If yanmar has replaceble cilinderliners)
They pull a lot of power from a relative smal displacement engine (5.5liter) so donít expect to run commercial hours. Can be worse, they have a 435hp with compressor same engine!!!
All in all a very good reliable engine that is very sensitive for clean fuel (Commonrail) with a good duoprop leg. (drive)
If you can do it a little slower go for the yanmar, 50% less electronic sh.. and alarm trash!!! Runs forever even on urine.
The Volvo leg (drive) is the better one.
It takes a few seconds more to reach speed but when u run, the yanmar can go and go and go forever.
Just my experience (run both commercialy and run a Volvo penta kad 44 with alamarin 245jet privat)
You can go for the rich kid Volvo with the fancy dials or for the bulletproof tracktor Yanmar and run forever

Many thanks for feedback - this is exactly the feedback I hoped to receive - much appreciated !
Being used to the ETEC G1 250 and now the G2 250H.O. I probably should not be over excited regarding hole shot .
I am lucky enough to have for both motors the diagnostic software but when you are on the water the last thing you want to do is to open your laptop ..
So looking very much forward to get out first time with an Yanmar .

Yeah, the advice is: if you buy a Volvo, you want to be near a dealer.

Is your observation regarding the Volvo and Yanmar legs from personal experience or mechanics observations? RBB have used both and the Volvos were the units with issues - crunchy gearchanges and a lot of sensor faults. Yanmar only make one leg AFAIK, the ZT370 and after five years of installs they seem to be holding up well. A lot of Yanmars got hitched to Mercury legs and it wasn't always the happiest of marriages. The Yanmar ZT350 leg wasn't a success and the clutch packs were all upgraded to cope with the torque...

...oh yeah, the torque, did I mention the torque? Yanmar are fitting extra torques to all their 8LV blocks. Apparently they found a shed full of it that someone had forgotten to put in the 6LPs....
