I have a mariner with an offshore mid and clamp bracket I had built for my boat. 200 efi block ported to 280 specs, vortex pistons, brucato with matching fuel curve, steel rod cage bearings , coned cle with fat prop shaft, mariner offshore mid, alien cowl. Motor is in very good shape with less than 50 hours. Only selling to get a 250xs. not sure how much hp its putting out but it ran close to 7 mph faster on a 2002 ally than a 225pm did. No issues with the motor at all. 7800. I can text pictures if interested or you can see pictures on scream and fly, thanks. 404-993-3157

Dale is one of the best engine wizards around. If Dale worked on it, then it is legit!
