hello, I see your asking specifically about the F200 4 cyl,, not the 6cyl, not the f225,f250,G2,or suzuki so lets stick with that. im looking into those same motors for numerous reasons. I have a 2001 265 express. our boats are similiar in weight I believe. I called grady and they said the 4cyl would be a good match for " me" i'll explain why later. also that it would be a direct replacement. I called Yamaha and they said 1. ask my grady dealer, 2. in my words not get on plane as quick "maybe". grady is putting these motors on one of their 27' cc and bowriders?? that weight similar to our boats. I will double check & give u the names. my yami/grady dealer owner has them on his 27' and offered to take me out. as far as prop goes im not sure . the 265 express had changes made in the transom area after 2002? to accommodate the heavier 4strokes they were now putting on em. I would have to do numerous changes to accommodate a heavier/bulkier motor, I doubt you would if you were to go 6cyl. these motors have only been out a short time so far I haven't read any major complaints.
