Sorry guys going to have to jump in here with the standard quote "2 > 4". Both have arguments in either way, however RIBS are very traditional boats, in essence they are the sports cars of the seas. A less powerful (albeit smoother) f/ does not suit a rib whereas a family cruiser it of course does. With the advent of the latest Optimax and Etec technology, the arguments against two strokes have been blown out the water. The inherently greater torque and power of a two stroke which used to be traded against poor fuel economy, greater noise and smoke is now defunct. At idle, the etec is as quiet as any f/ bar the Veradoro, however the Optimax is still fairly loud. They also both consume the same amount of fuel as a typical 4/.
All engines have their faults, in the beginning, etecs ate their injectors, Optis ate their compressors and Yamahas blew up
. No engine is fault free but you only find out about the ones that go wrong, not the thousands that are fine for every one that is a dud.
