Welcome to the forum!
Nothing to worry about with the Volvo drive. There are plenty of them out there still going strong. Props used to be a bit of an issue, but one of our former members worked wth Solus to develop a prop that almost everybody agrees works very well. Plenty of Volvo knowledge on the forum - I'm sure we can walk you through anything that might come up.
