I have attached a picture of where my motor sits in the water. I showed this to a mechanic and he said wow, you need to lift it. I will try this weekend to lift it. I have a yamaha jack plate, does anyone know if you for sure how to slide it up? is it just the 2 bolts on each side? Thanks for all your help so far.

So my cavitation plate is 2 1/2 inches above the bottom of the boat. I was told that would be better for top speed, yet I cannot get top speed. Does anyone know on your 2190 where the motor sits? I did talk to a guy and he said that is where I am getting purpoising from. He recommended setting it down 2 inches on the jack plate. Let me know your thoughts/opinions on this and thanks for the information you have given already.

sounds like the 3600 is the most common. Thanks for all the info.
