Years of motors were 95, 97, 99, 01, 04, and 07. All were EFI Mercs. Correction, the 99 was 175, all others were 150s. I guess i thought the Pro XS Optis were a hotter motor than the EFI motors. I may have been mistaken on that one as i have heard that the Pro XS 150s are just a sticker difference. Your thoughts? On to reservoirs most trips are to Truman with the occasional Lake of the Ozarks, Table Rock or Perry on the Kansas side.
