Re: Yamaha 9.9 Four stroke outboard
Hi,<br /><br />If You go to Yamaha US website You can have a look in the Owners manual available there in PDF (You can view it but not print it).<br /><br />
Link <br /><br />For example in the manual for 2005 F9.9 4-stroke they mention:<br />NGK CR6HSA with gap 0.6-0.7 mm / 0.24-0.28 inch.<br /><br />You can view Owners manuals back to 1998 on Yamaha US website.<br /><br />Hope it helps.<br /><br />/Bo
