"Hello,
2 questions I'm looking for some help with.
1. I have a 2000 7.4GSiPEFS engine and need to replace the lower exhaust bellows. The Volvo diagrams show this is part 3852742 however upon looking at this part it is too short by at least an inch. Someone had universal exhaust tube on there before so I couldn't get the number off of it. Any ideas on this? Anyone know if the 3863450 that spec'd for the 7.4DPX is any longer?

2. When I bought my boat the title says 385HP for this engine, however when I enter the serial number at Volvo it says 405hp? What gives? And what exactly was the difference between the GSi and DPX engines?

Thanks!
Jason"
