Related to another post...but as I started changing plugs...they were all coming out perfect. The engine only has 70 hours...so with Platinum Plus I would expect that.

I found the problem on plug 3, actually turns out it was the wire...it was burnt and core was jacked.

So question is...I have twin 496, and it will take me (who really sucks at this stuff) another 4-5 hours or so to finish changing the last 5...and I am not even sure I can get to 3 of them with the tools i have.

Can I just change the 3 and leave it at that...since the once coming out were near perfect...what harm would this cause, if any? Thanks in advance!

You'll be fine. Change them all out at the end of the season if you feel better about it.

i had only one foul out before. Change only one will work fine IMO.

If the boat is still running the same speed dont even bother. On a 496 you will know they are going bad - the boat starts to lose top end speed.

I think the manual says every 100 HRS.
