Mr. D. YES, tunnel drive AND the patented Penn-Tone exhaust (ya gotta love it). As I said, I am under severe time constraints (no explanation will be given-sorry) and Ms. PH's suggestion came a bit too late so I'm locked in, as it were, to my purchase unless I can flog the brand new system and buy the "better" system. As has been mentioned VERY many times, all boats are a compromise.
The really weird part is I have yet to see the new (to me) vessel in person! Life is full of surprises and this will be one of them. Even picked out a new name "PY-jammas" although I'll have to float that one by the Admiral.
