Thanks for posting this. Hadn't seen the batteries in the back like that. Pretty sweet.
Do you have the part number for that volvo penta bracket? (no worries if not) Might look into that next summer/winter.
Also, the air filter is the same right? Just on the end of a silicone elbow to make room for 2nd alternator?
Selfishly it's GREAT to have another 8.1 247 on here.
