Firstly, that Velineon motor is on the hot side for this setup. So we don't know the diameter and pitch of the prop. Firstly do make sure the prop is the proper turning prop for your boat. Looking at the back (transom) the prop rotation in relation to the leading edge should turn counter clockwise. I would run the boat for a minute and bring the boat back in. Check the temp of the motor and esc. If it is still cool to the touch, run it for another minute. But run it full throttle, never run half or quarter throttle. Things specially the motor and esc will heat up quicky. And heat is a great way to kill your esc/motor. If it is still okay to touch then try running it again for a few more minutes. No longer than 5 minutes. Check again. If it is warm to the touch then you're okay. I noticed that your motor has cooling coils, which is okay. But is your esc water cooled as well?? Remember when running boats, your motor and esc needs to be water cooled as they are locked in the hull with no air coming in to cool anything. And I don't recommend running a any other motor in boats other than ones made for marine use. Unless you have some experience. I would strongly suggest figuring out the diameter of the prop. If the boat is running a little hot, you will need to prop down specially running a motor that is 3000 + KV. The higher the Kv the less torque it produces and the smaller prop you need to run.
