Thanks a bunch Paul. Actually, Latestarter must live quite close to Portishead?

Let us know how you get on today.

Sea Trial is Saturday VP, assuming the plans come together.

Easy enough to convert hours to miles, in a traditional truck.

Most medium commercials rack up around 30mph average during their lives. Sure, some are in the city and do less, others will average a bit more, but 30mph is a fair shout.

Take an engine of 2000 hours, multiply by 30 and you get 60,000 miles.

This would be very little in a 7.5 tonne truck.

I would expect the truck engine to do around 500,000 miles and be serviceable if not a bit past it's prime, which is just under 17,000hrs.

IMHO etc etc...

NR, this ignores duty cycle. Is the duty cycle in a boat, the same or different in a truck?

Tricky to say, as they will vary so much.

The truck will do around 50000-75000 miles a year, while the boat may take 30 years to do this!

However, once started, most boats are used for three to five hours at a time where we come from, then perhaps turned off for a week...

Yes, but the real question isn't the running time, but how hard the motors are working during that running time. If running at 90-95% wot most of the time takes a lot more out of the engine than 70-75%. That is why Latestarter and VolvoPaul said it depends on how much fuel is consumed per hour when running. This is the key question.

Absolutely spot on..

Super motor a real icon, however later 3208 TA 'E' ratings were a bit of a spoiler the 450hp/456mhp was a real lemon.

I use oil sampling all the time, but never this one shot wonder stuff. Regular sampling gives wear trends and whole bundle of useful data. Snapshot samples are used all the time in US for pre-purchase surveys, causes many sales to abort because of screwy #'s which are subsequently discredited.

Far better to have engine survey by distributor, proper blow by check and a piece of paper which is money in the bank.

Are you suggesting to steer well clear of this 450hp version? Even if way under 500 hours recorded.
I rather fancy the idea of an Azimut 46 as a cheap floating caravan for my med venture but most of these seem to be fitted with this motor.

As with many threads
Where did the OP go

I don't know that the AZ46 had a 450hp version of this engine. I had an AZ46 myself with Cat 3208TAs and the rated hp was 425hp. FWIW and as I said before, I've had these engines in 3 boats incl an AZ46 and they never missed a beat. At 500hrs, I would get them checked out by a Cat dealer and if he gives them a clean bill of health, no worries go for it
