282 Engine Mainteance & plug access

[PGI CONCH 0]

Considering purchase of a 2004 282 Express. Appears to be twin VP 270hp engines. Not sure of the model as it isn't listed. Wondering how accessible the spark plugs are on the outboard sides of each of the engines? Also wondering if there are any other maintenance headaches on Volvo Pentas. I've worked on several Mercruiser models over the years, but not VP's. Thanks in advance for any thoughts and feedback.
