Bob,

The answer is - Yes - to both

Somehow I am certain that you didn't ask the entire question, but I can
only guess.

If you are asking will the boat go twice as fast - No - again to both

This then comes into hull dynamics that will take much more information
effectively answer.

Do two 9 hp motors equal one 18 hp motor?

In terms of boat performance, not necessarily theoretically.

Thanks,
