Well if you want reliability and durability, you should be looking at the new evinrude e-tec:
So over engineered and durable, that there is no scheduled dealer maintenance for 3 years. My local outboard dealer stocks johnson, evinrude, mercury/mariner and honda, but swears by these. They use barely any oil, are very quiet and clean and are seriously light. There were twin 90 e-tecs on the back of the new Redbay Hurricane at the LBS.
A sworn optimax man myself, I still would have gone for one of these on my new boat, but i needed a 135, and they only go up as far as 90 at the moment.
Also don't forget that there's a new optimax 75 out now as well.
