I am a new member to the forum here as well as a first time owner of a pwc. I have owned boats for many years but none with a jet drive. I bought my Spark about four weeks ago and have 5 hours on it. Today I sucked up a stick and apparently damaged the wear ring. I took it to the dealership where I bought it and they pulled the stick out for me, and advised me that it may or may not be damaged. Put it back in the water and sure enough the engine revs but no go. So what should I use to replace this wear ring? The 70 dollar plastic part or the 180 dollar stainless steel part? I understand the plastic is sacrificial but wouldn't a stainless ring and impeller chop your average stick and send it on through? What am I missing?
