I have a Mercury V6 200 HP? <br />Powerhead Ser# D137049<br />Leg Ser# 6110255<br />I would like to ascertain what I have here. Firstly are they compatable? Secondly identity for parts ordering.<br />BOB (Laddies) answered this previously but left with the note "could be different" leading me to reask the question. <br />I am not satisfied with output is the reason for asking compatability question. I have an 18' Bass boat use 19 pitch prop at 3000 ft. elevation and it's a dog out the hole. I am currently working on Carb overhaul because it did sit for a while and I feel it that they are gummed up. ERGO Ser# for parts which started this Thread.<br />Thanks for any help
