Re: outboard

The half throttle comment was mine, and it only works because the 
9.8 and 15 hp engines are the same size and weight.  But I can 
feel a huge performance difference between the old Honda 7.5 and 
the current Johnson 15.  (I think the Honda could have used a 
better prop.)  I don't know what actual difference is  because I 
installed the knotmeter after I changed engines.  And I probably 
wouldn't believe it anyway, because the uncalibrated meter 
sometimes tells me I'm doing six knots idling across the harbor 
without a wake.
