I'm into my 4th season with this motor after repowering my 16' Princecraft. Except for the first year, I have hada continual problem with fouling of the spark plugs with the engine stalling and won't restart. This happens after I have been trolling. I've used carbon guard and continue to use 2+4 and I've switched to XD-100. The latest episode happened after about 12 hours or so of total trolling time (about 4 outings) and the engine stalled after hesitating on acceleration. I'm pretty sure this problem is all about trolling with the etec because it seems to run fine if not trolling.

Does anyone else have a similar problem with trolling with etecs? I'm thinking that for my situation, a 4 stroke may have been a better choice.
