Check the sail drive
oil for colour and make sure its not milky. I have Volvos with 4000 plus hours on them on a 2000 model year
hull #24. Sail drives have been replaced once as the previous owner left them several years without checking / changing the zincs,
electrolysis ate them away. If you have the option pull an
oil sample from each of the engines and have it tested. Will show any excess metals and give you a base line should you
purchase. Check the
saloon floor for soft spots. I have not had the issue but have heard of a few cases. check the rubber boot on the
exhaust /
heat exchanger exit. The Volvos are prone to
corrosion issues at the
steel elbow there. I have done one of those and one heat exchange unit. I have good quality
bronze through hulls but they were on the
boat when I got it 5 years ago. I do not know if they are original or not. I have heard via this site that there have been issues before but I believe it was on newer model year hulls. Mine has original
ports and hatches. Some of the hatches have crazed
Lexan that I'll replace someday.
Wiring in mine is a rats nest that I am trying to
work through. Part
Lagoon part 3 previous owners all with different ideas as to how a boat should be wired

Get a
surveyor you trust to give it the once over and good luck. PM me if you wish.
