Mr. AE. I tend to agree with Mr. CP regarding parts availability for certain Volvo engines although my
opinion is based solely on anecdotal "rumors". One other issue that I would be concerned about is space in the ER. Two engines and a generator in there might
make it tight for some routine maintenance. When you go and look at her, get into the ER space and try to reach; oil filters, water pumps, stuffing boxes, starter motors, alternators, batteries etc. and consider what position you have to bend your body into to achieve turning a wrench on any particular device. THEN, consider if you can maintain said position for 15 minutes to 1/2 hour. Can you get TWO hands into that space WITH a wrench or screwdriver? Space man!
