Re: Difference between 2005 and 2006 90 HP Merc 4-strokes
Welcome to iboats.
<br /><br />No difference that I'm aware of. With the pending separation of Yamaha from Merc, I doubt Yamaha has let any of their new improvements trickle down to the Merc product. More of the Yamahas of that general size have been upgraded to EFI over Merc's carbed versions. Still a good product, tho.
