Hr's on plugs ????

[Dave Q]

I am wondering why my Yam 2006 f75 manual say's to change plugs at 200 hrs. Truck/car plugs go for a long time. Why the diff.

I think its cause cars dont run wide open most of there lives

As I recall....Dave's boat goes about 1.8mph to 2.2mph most of the time. ;)

Aw heck...go for it, Dave. A plug usually costs less than a crankbait...and you don't need near as many spark plugs!

Thanks mr Mac. I did change the plugs ....was just killing time wondering why the big big diff. hope you had a good season :)
