Official Yamaha Jetboat Periodic Maintenance By The Book

Yamaha Periodic Maintenance Chart for Jetboats. Each model and year has one. Find yours and go through it each year. This year I found things stuck in my gravity drain. I also found loose screws, bolts and nuts around the boat and I found water in my gas tank storage hold because I forgot to install the drain plug last time (face palm). A deep maintenance dive into your boat is a great way to still be "boating" during any down time. Do it now so you can boat later. Features include Hawaii, Oahu, Yamaha Jet Boat, SX190.
