so to start out this is the first jetboat that i have owned. i have had jetski's and boats in the past though. wondering if there is anything i need to know before the season starts. i got boat with a blown motor, a new one will be installed in the next week or so. i have a few main questions to start, first question is there a way to check my wear ring before without taking the jet drive off or putting it in water to find theres an issue. also wondering what the minimum recommed water depth is for this boat. my is an 01 sportster le, it is a carb modle 951 motor. also is there a recommend impeller to upgrade to that is a great all round impeller. thanks for the help in advance
