RE: CMB motor
Well...here is what my thoughts were, right or wrong, when I got my engine. Most boats are running surface drive now. I thought surface drive was as much about RPM as it was about power. With this in mind, wouldn't even a mono (with surface drive) be better off with an HR engine, IF the HR is made more for RPM??
Anyhow, not really relavent since you are running a hydro... Never had an RS to compare the HR to, so don't know which is actually better.
