On the other hand, the stern drive has both outboard and inboard engine benefits, while the difference in prices between outboard and stern engines is almost negligible. Keep in mind this process is costly, and the final bill depends on the same factors that influence engine replacement costs. same position when running as it is when stopped, when the alignment That's because larger shafts tend less toward self-centering particularly when it is hauled.

On average, the cost of maintaining a boat is around $2,000 per year. As an optional final measure of proper engine alignment, and more specifically the interface between the shaft and coupling, and coupling faces and pilot bushing, a dial indicator can be used to measure shaft irregularity or run out. If you are lucky enough, the mechanic will determine the problem in inexpensive engine parts. Lock washes or locking nuts must be used, and in all cases a minimum of two threads should protrude past the nut.
