boat I've put a deposit on has twins.
Mechanical survey result was excellent condition. Has 800 hours both.
I have 2 of those. Both were originally installed in a Commander 30 and removed to allow that boater to go much faster with bigger Volvos. I got them at 1500 hrs, redid the injectors before installation. No unusual expense then, nor since. That was in 2000, so I now have 20 more years and ~2000 more hours. I have had no issues whatsoever with one engine, but the other had a failure of its raw water pump and developed a hole in its oil cooler. No silly expenses for either, No difficulty getting parts when I needed them. The water pump was an in-stock item at my local VP dealer, the oil cooler was repaired and has another 10 yrs on it without issue. Great engines, start instantly, even in the winter. They smoke slightly on startup, but it clears on warming up.
If you read the posts on Volvo threads here, you will see strident anti-Volvo rants by a very small but vocal group. Claims that parts are silly expensive seem to be an East Coast thing, claims that Volvo doesn't support "legacy" engines shouldn't now apply to these, but if you plan to keep your boat until its engines are 50+ yrs old these may then be called "legacy" and you will get to evaluate Volvo support at that time yourself.
I also have a Cummins ISL 400hp, and when I recently (June 2020) shopped for oil filters for both my Volvos and my Cummins, I got 2 for the Volvos for the price of 1 for the Cummins. In the same store, same price per hp. I have found other comparatives that measure up the same way, so won't credit reports by posters who don't supply real evidence.
