Need a tach tool for testing RPM's 2 and 4 stroke (And others)

[DamianJP]

Hopefully my post isnt in the wrong place, figured prop section would know of a tach tool that had ACCURATE readings.

Looking for a tach tool that I can set/check 2 and 4 stroke outboards I work on. Plus if it can do other small engines too that would be good(ie: mowers,chainsaws,weedeater,ect).

I had a Actron CP7529 but only used it twice and it was stolen. Never got to see if it was accurate, but both motors dialed in good.

Was looking at a ES EZ Tach Plus 328, because I never really used the light feature.

Maybe someone could point me in the right direction. Light feature a nice option to have? Any other features I should look out for?

Again hopefully my post isnt in the wrong place.


Thank You for your time/help,

I use a photo tach from amazon. I think it was $11

Tiny tach are apparently good.

Scott is this the one?
Hows the no contact readings?

Iv'e been hearing this aswell.


Can these units handle idle speed screw adjustments, and other tests too?

Not looking for a permanent tach on motor, just a test tool I can use for 2-4 stroke outboards (And other small engine and automotive work).

If they can , I need to grab one.


Thank You big time guys,

I think I have this one. https://www.amazon.com/AGPtek®-Professional-Digital-Tachometer-Contact/dp/B004Q8L894. Either way it was $11, so I dont feel bad if I drop it

For outboard use, would like to see anyone pointing a tach lasser against a flywheel with removed cowl while boat is running at full throttle. Are only good for idle adjustments or running full wot revs inside a test tank with a special test prop.

A Hardline induction tach HR-8061-2.model will be more suitable, esay to install and remove. Good for 2-4 strokes OB's and max 2 cylinder engines. Measures all the rpm range at all throttle settings, ideal for prop maximizations and records hour of use.

If wanting to test more cylinder engines than 2 and up to 8 cylinders, will need model : HR-8062-2

Check Iboats, Amazon for them...

Happy Boating

Doea take 2 people to check OB WOT.

Even if you purchase "Hardline induction tach HR-8061-2" for the WOT O/B check, I'd pick up an inexpensive photo tach per Scott Danforth. They are accurate and very versatile. Especially when you are tweaking in a small engine governor for rated rpm, checking electric motor speeds, etc.

Well, OP didn't say a word about Electric Motors, he stated "Looking for a tach tool that I can set/check 2 and 4 stroke outboards I work on. Plus if it can do other small engines too that would be good(ie: mowers,chainsaws,weedeater,ect)"

My guess is that if on a budget or wanting to spend the least on a tach will definitely go per the first option...
