I'm off on holiday tomorrow so I'm at home without a pricelist in sight!! As far as I can remember the D3-160 retails at around £13500 give or take a little. As I work for the head office and we sell engines through our dealer network I have to be a little careful about what i say here in case they are watching!! We can only quote retail, our dealers get a discount off that price some of which is passed onto the customer but legaly we cannot dictate what they sell at. You will not go far wrong with either Chris French at French Marine or Bob Brammer at Volspec who are your nearest dealers. There is also Peter Saunders at Northgate Marine, he has just moved from Beccles to Lowestoft, all of them very experienced Volvo dealers. Please don't quote me but the discount can range from 15 up to 30%. Plus if your existing engines/drives/props are servicable there is the outside chance to part ex them to the dealer or sell them on yourself.
As you know there are also costs involved with installation, electrics as the D3 puts out 140 amps, the transom shield may need adapters at aprox £300 each plus you would need new props and possibly new throttle controls as well.
I'm afraid it all gets very expensive!!
Still if your 32's are behaving themselves then you should be ok for a while yet. The only major problem that I'm aware of is the cylinder heads can warp if they are overheated and are very, very difficult to source.
Right I'm off to jump on a suitcase to close it after my wife has packed it
