Ok thats another data point for me. I need to figure out if i can adapt the
little tach I have to work with a 1cyl-2stroke and figure out the conversin
math to see if I'm getting the RPMs i should have.
Tohatsu/Nissan/Mercury/Mariner motors have at least 3 pitches available, 7,
8, and 9 inches. 8 is stock. I think it would be prudent to carry a spare
prop anyways, so maybe I'll pick up the 7 and see how it works.
