"I have three outboards I want
"I have three outboards I want to check with a tach (might re-prop, etc.). They're an Evin 1979 9.9, 1992 15 and 1996 25. This is one of the very few times I need a tach for these motors and I'm wondering what sort of multiple-purpose tool I might use to check the rpm. For instance can I use a dwell tach for a 4 cyl. and divide (or multiply) the result? I could bother a marina, but I have a few props and I'm not likely to buy anything from them (doesn't seem fair), though maybe they'd rent me one or something. Any help or ideas are wanted.
