Any luck dredging up some examples of manufacturers using twin
inboards rated at only 50-60% of the HP used for single engine
applications in the same hull?

Aside from needless remarks about "stupid" people "running around
hysterically trying to move the goalposts" we actually had a boating
related discussion going. Please don't just disappear when challenged
to provide some examples of your theory. Doesn't have to be elaborate,
maybe something similar to the format I used when providing the
example that validates my observations regarding this issue.

Looking forward to your response on this issue......
