Author	Topic:   OUTRAGE 25: Engine Mounting Height
summersalt	posted 04-19-2007 09:51 AM ET (US)         The shop that mounted my new Honda 225 used the exact same mounting holes that the 1996 Johnson 225 had occupied. They are both 25" engines. The problem is that the Honda is creating a V-spray at 5-knot to 15-knots which the Johnson did not. Does the Honda needs to be mounted higher? The shop will remount it until I'm happy and I'd like to get this done in one shot since they're being very cool about it. [The boat on which this engine is mounted is a Boston Whaler] 1983 OUTRAGE 25. Thanks

The bolts will stay through the holes in the transom, but the engine can be adjusted to slide up or down by loosening the 2 bottom bolts & removing the 2 top bolts & tightening them after you raise the engine. I would raise it 1 set of holes first & see if it cures the "V". If you look at the bracket you will see what I'm talking about. Sal

jimh	posted 04-19-2007 10:02 PM ET (US)             As a general rule we usually use statute miles per hour to specify the speed of our Boston Whaler boats. Most of the time a Boston Whaler boat is not on a voyage on the high seas. When on the high seas it is common to measure distances in nautical miles, but on most inland and coastal boating it is more common to measure distances in statute miles and to use statute miles per hour as the unit of measurement of speed. Another reason for preferring statute miles per hours is that any time someone mentions "knots" there is an ambiguity. Are they really talking about nautical miles per hour, or have they just slipped into a nautical form of speech but really mean statute miles per hour?
