Thin-wall spark plug wrench for Yamaha?

[2cycle1]

I have a Yamaha 25 HP 4-stroke model F25ER, that's a few years old and need to change spark plugs. I know it takes an 18mm, deep socket wrench, but the clearance to the casting around the plug is really small and I haven't found a deep socket or spark plug wrench that is thin-walled enough to work. What have others used??

I'm thinking of buying a cheap, deep, 18mm socket and grinding the outer wall down, but I know tool-steel is hard and may not grind easy.

Help!
Thanks!

You can buy a cheap little tool that is made for motorcycle engines but it isn't a socket that can mount on a ratchet....or you can get a
Blackhawk, Snap-On, Matco, or other high quality socket that uses better steel and doesn't have to be so thick to be strong....you'll find lots of applications on Yamaha's that require better tools to get clearance.

I have an '06 50hp 2-stroke and I use a craftsmen socket...not sure if you've tried one of theirs? Even if you have to buy a $30 snap-on socket, it'd be the last one you ever have to buy atleast!

I have a 2005 25hp Yamaha and this is what you need. Cost me .50 cents bought from a lawn-mower shop.
