    tuner may have broken off,seen it a few times.drop the lower off and look up inside the mid,if the the tuner doesnt fall out first!

    I just put a new lower unit on it so if it's the tuner does that mean the powerhead would have to be removed?

    id drop it again and have a look up inside with a flashlight,tuner may be broken/coming loose.you will have to remove the powerhead and exhaust adapter IF this is the problem.
