Cost for rebuild

[spareparts]

check the gear lube, look for metal on the magnets, its could be the lower unit making that noise, even though it sounds like the power head, some times the noise travels up thru the exhaust housing and its hard to tell. I've taken the lower unit off motors just to eliminate it from the noise. Regardless of the cause, it willl be far cheaper to fix now than it would be to wait till it got worse
