I can't tell you all the differences, but it may not be just a SW change. I Would be checking to see if the turbos are the same as one obvious...
Seized wastegate, variable vanes not operating, all causes of failures in modern marine diesels. Was talking yesterday to a person who had...
At 5000hrs and many years old you are buying them on the basis that you may need to spend money on them. There is no doubt that well maintained...
It may not be relevant to your engine, but we recently had an issue with water in the rear cylinders of a Mercruiser (VM) 4.2l 220hp. That was...
I currently have 7 diesels in boats. 4 Common rail electronic engines and 3 older mechanically injected engines. The ones that give the most...
My twin 330's run at 15lph (combined) at 8 - 8.5knts in my 43ft planing hull. L/NM basically doubles if I go from 8knts up to 18 - 20knts. We also...
I run my twin 330hp 5.9l diesels at 1200rpm rather than the rated 2400 - 2500rpm cruise speed for around 85% - 90% of the time. They do get a...
As previously mentioned, buy one of those cheap IR thermometer guns and shoot the whole cooling system on both engines for comparison. I think you...
TB - there are only a few possible 'normal' reasons for the overheat if the engine is running well and not losing coolant. First and most likely...
Have you checked the raw water flows at high rpm or only at idle? A restriction like an elbow etc may not affect the flow at idle, but may do at...
I don't know that engine, but after the impeller and heat exchanger the next logical things are a blocked exhaust elbow or intercooler (probably...
I agree with this. I have twin 330hp in my 43fter, and yes I burn 21gph (combined) at 18 - 20knts cruise, but at 7 - 8knts it is only 3 - 4 gph...
Changing engines is going to be expensive. I don't know the 555's very well, but at 270hp and 9.1l they should go way more than 2000hrs, but they...
Just to set the record straight, Yamaha build the 4.2l (~315hp) diesel for Toyota. We mostly know it as the Toyota Landcruiser engine, but they...
What engine sizes is this correct for? I know at least some Yanmars come out of BMW's factory, and others out of Yamaha's.
If that FL6 engine is the 5.5l one, then no, the drive almost certainly won't handle it.
As mentioned above, it is the torque of the engine that is the concern, not the hp. A leg that might take a 225hp petrol engine making it's hp at...
Can't answer for Aus, but there is a market in NZ if the price is right. The KAD 300's are not one of Volvo's best so I would be wary about them,...
Whitepointer - I could be wrong, but they would have had to be back in the early 1990's or earlier, and I think that was D'tronic time which was a...
Lots of things don't quite add up with this. If you are at 7knts just above idle (say ~900 rpm?) then those engines should be at say 1200rpm -...
