We put Mercury 200 hp on both mine ex 1900SS and my friends 2100SS we both fitted Land & Sea lifts, foot throttle and Torque shift propeller. 2100SS was faster by 4 knoths but the 1900SS gave softer ride in waves, also is more sexy looking than the old 2100SS design. I miss the old beauty and would love have another one again instead of my Fletcher.
