Thats a bit shite really.
Sorry if this has already been covered.

Hi Chris
Um not sure about this.. but it certainly been frustrating finding out all about this... The honda installation guidelines gives a range and the 21" transom is within this; and yes it should have a longshaft based on this.
It seems that a long shaft is not just a longshaft. If anything Honda are longest in the range that I have just checked out!.
Honda 90 537mm
Suzuki 90 508mm
Evinrude 90 508mm
Mariner 90 508mm.
To me it means when you choose your next outboard check:-
1) your max hull design speed (mines 42 zodiac tell me)
2) your max HP rating (mines 120)
3) check the transom height (21)
4) max transom load (165kg)
5) check the length of the shaft ie 508 or 537mm....
whats been interesting to me I have spoken to many enthusiasts and professionals and there are just so many different opinions! - and it seems many will drop it on the transom shoulder regardless of whether that means its set up correctly.
What I can tell you is that none I have contacted even seemed to bother to check these details - most just seem to check the max HP rating for the hull and thats it - not surprising as both the Honda and Zodiac manuals only refer to checking HP rating and height of transom - nothing about max cruising speed (i guess it assumes the HP check covers this one) or max transom load.
Makes you wonder how many boats might actually be set-up incorrectly or have outboards that exceed the max transom weight.....
I wonder how any Rib net enthusiasts have checked theres out?
