Like Josh, I find the tachometer is most useful for shifting the transmission. With my 3MQ30, pushing the throttle down too far shuts the engine off...not what you want to happen while docking. Unfortunately, my tach just recently only works when the engine is cold...once up to temp, its stops working. I miss it when it goes on the fritz.
