I have a 2011 AR210, what should I gap my spark plugs at? Reason I'm asking is I lost 10 mph off my top speed since my last service and I'm going thru the process of elimination to get back up to proper performance. Thanks!
 
From another thread @txav8r stated that the correct gap is .032. I purchased the wrong iridium plug that had ~.04 gap. I used the special gapping tool to reduce the gap to .032 and I'm able to get full performance from them without issue.

Crap - I missed that you had 1052cc engines... the .032 gap is for the 1.8's..

Sorry

Not sure what engine you have however you can go to the home page to locate your specific boat and year manual to get the operators info for exact recommended gap.
