On my 03 Classic / 200 Opti- Had my new hydraulic steering installed to replace my cable system and WOW. I have my best numbers to date on my classic with 200 Merc Opti. GPS 73.7 mph, 5800 rpm. The biggest difference is the ability to keep the boat balanced, as my little twitches are not resulting in over-correcting- as they were with my cables. Keeping the nose balanced is a breeze now.
