Re: Johnson 9.9 or Mariner 8 hp ?
i have similar motors, a 2001 merc 8hp 2 stroke and have several, omc 9.9 and 15s and i would choose the johnson. the reason being, is my 8 hp merc doesn't put out as much power as i think it should, i think it's based on the 6hp block. what kind of boat and how is it loaded, my merc runs great, but doesn't do well with a heavy load, the 9.9's do better. lastly, omc parts seem cheaper for some reason.
