Welcome to the club.
Clinton tournament is fast approaching. Ill be in the same boat. 899 HB to learn. Doing the same as you, reading the owners manual, watching the videos that came with it, watching youtube, reading everything I can find on it. Although I still have to install mine. I need to make one more cabinet for the kitchen, then I can tear down the wood working tools and get the boat in the garage and get it ready for the season. I will be replacing the tires (3 years old) this year while tending to the bearings.

Would that be Birdy's unit he had for sale earlier this year?
