Hello All.
I'm keen to fit a tachometer to monitor engine speed on my J35TEL3EEM 35hp 3-cyl 2-stroke outboard.
A genuine new item is beyond my budget, so I'm looking for a used unit.
I have yet to see a genuine Johnson tachometer advertised locally here in Brisbane, Australia. But tachometers for other makes, as well as generic units, are much more common.
What do I need to know to avoid buying something incompatible? I know alternator pole count is important, but how many poles does my alternator have?
Any other trap to be aware of?
Thanks.
