Hello well i was reading some old posts from a few years back and ran into a post about the plastic intake manifolds on the 98 115 intruder, it said that the manifold after a few years warp and they start leakinf air which would cause preignition detenation due to lean fuel mixture is this true maybe someone has some information on this issue, i dont have a problem yet but i do have a 98 115 intruder that is getting some years on it so it is somthing i would look out for , is this a common problem with this outboard motor maybe some experts could answer this question for me or others that has this motor thahk you.

Very rarely I've heard of this problem. Maybe somebody else has.
