Just about all (electric start) outboards built within the last 30 or 40 years use a tach that gets its signal from the alternator. They count the AC pulses from the alternator. Check it out, but I think your 50hp has 5 pulses per revolution.
So, the question becomes does the tach in question have a selector switch to determine the number of pulses? Well backing up, I suppose the first question is whether or not it is an alternator tach.
I don’t know the answer to those questions.
