Also, how does the M-45 ride in rougher water. 

[M-45. Looking for used late model. 250hp]

Looking for a well maintained used M-45. Also, I’d like feedback on how it rides in rougher water as it will be on Lake Ontario. Would love to ride on one for a few minutes. I’ll buy the gas and the drinks. Wondering if it would be good in rough water or is the SS line better like the 235SS?  Not sure if the 235SS has a head though.
