It's hard to buy a "Yacht"

We had a single DD 8.2T -- 220 hp, IIRC -- in a previous boat, worked fine. Wasn't meant to be a fast boat, and the builder's common alternative had been Perkins starting at 165 hp and increasing to about 220 over the life of that boat model.

There was a significant recall mod, increasing the headbolt size (to IIRC 15mm), otherwise no other issues I was ever aware of. But then again, we didn't flog it...

They're not held in high regard, these days. And it's probably not like parts are growing on every tree you can see...

In the boat we had, as they age, a common repower is a Cummins 6BT... of various hp/ratings.

If I remember correctly the 8.2 had two different HP outputs of either 175 or 300 HP in 1986 or so. I had a couple of the 175 HP units that GM put Stamford alternators on for 75 K.W. A.C. generators on a vessel that the gens survived two years before being removed as one threw a con rod out the side of the block @ 2,ooo hours or so and started a fire and the second one kept having constant cooler failures with either the fuel cooler washing the cylinders with lube oil dilution or the oil cooler polluting the system, either way they were an abject failure as marine generator sets and weren't long on the market in that configuration.

The Meridians sort of have a following too which makes resale a little easier
