ok first things first , i have a 1996 proline 251 had a merc 225 efi with a single engine bracket! i since took engine off and currently parting out ! the boat placard says rated for 300 hp , here comes the tough question what should i put on with todays technoligy ? yamaha , evinrude ,merc, ect need input. i like yamaha so far ,! dont really wanna deal with 2 stroke oil ! another question is i wanna put a 350 but if i can only handle a 300 being thats what the placard says then so be it but, would i be able to put a 350 ? any input would be greatly appreciated ! and if u have had a repower done what do they include or what do u pay extra for when installing ! last but not least who or where are some places in middlesex or monmouth with really good quality work with installs and customer service
