I have just ordered a 435 for a long trip, and I was wondering if I could clarify a few points
1. The boat comes with Volvo MD22 as standard. You said this had problems, and you would use a Yanmar in future. The MD22 is fairly commonplace, although the Yanmar has a better reputation. Is this a problem with installation, or just a poorer engine design in your experience? Maybe I should switch if possible.
Engine - I cannot comment on Volvo's quality (MD22) - I did have a lot of problems with the sea water pump, but what annoyed me most was the bad after-sales service, even while the engine was still under guarantee. I just hope Yanmar are better in this respect. My Volvo is running well, so no complaints on that score.
