drives take a chitkicking in rough water or when infront of big power, Bravos that is. Learning to baby the drive out of the hole and to throttle it correctly will save you thousands in the long run. Most smaller, lighter boats with stock power will have good, long service life from the drive if cared for properly. I have seen bravos with 500hrs on them with no failures. Change the oil every 15 to 20 hrs, do not hammer the throttle out of the hole and always pull back when the prop leaves the water and with a stock mag, you will be fine for years.
