Forgive me if it's been posted before but is the Denso 3381 an exact replacement for the LFR6A? Being told it is but the cross reference is saying it's also good for the LFR6A-11.

The plug th reference may cross to both. The difference is the gaps. And from what I have read, gapping the -11 down to what our engine spec is can possibly cause an issue/failure. Other than that I believe the plugs are the same.

Are these the correct spark plugs for the yamaha jetboats ? Have anyone faced issues when using these plugs ?
NGK V-POWER SPARK PLUGS 6668 LFR6A

http://www.sixityauto.com/8-pc-8-x-ngk-6668-v-power-spark-plugs-6668-lfr6a-tune-up-kit-set.html


EDIT : A set of 8 of these V-Power plugs is 40$ whereas the regular spark plugs are close to $7.77 each on Amazon

Yep, NGK LFR6A is the OEM plug for your boat. No issues.

Good catch on the $5 discount! I ordered some before all the rest you the 1.8L knuckleheads eat up all their stock!
