what kind of tach

[rocket rich]

what kind of tach do you use for small 9.8 four 4 stoke motor . it's about the only way to help set up motor. These new motor Merc, rudes , tohatsu, nission, areall made by the same company and paint is the only difference also motors are 2 inches longer with a need to build up transom.

Some buy a tinytach.com tach, I bought this which is similar and only $ 13, just got it and haven't used it -http://www.amazon.com/Penny-Tachometer-Stroke-Outboard-Mercury/dp/B00ACDP6YU/ref=sr_1_5?ie=UTF8&qid=1401556117&sr=8-5&keywords=tachometer+boat I'm gonna use it to verify the accuracy of my console tach.

Unless you have a charging system on your motor you will have to use something like the Tiny Tach mentioned. I have used them and while not as good as a regular marine outboard tach they will get the job done.

X3 Tiny Tach runs off watch batteries. I strapped mine to the tiller arm with rubber bands where I could see RPM's . Wire runs from tach to one of your spark plug wires. Simple to use.

I agree with the Tiny Tach. Great device for small engines. Had mine for 5 years before I sold the boat.

I didn't even know you could get a tach for the smaller motors. Done went an learnth something new today.

If you go with a Tiny Tach make sure it is set for 1 spark per rotation. I think the default setting is that.

Now if someone will tell me why I need one I will have learned two things today .

I tried my $ 13 Penny tachometer today on my Merc 60. It read pretty close to what my boat tach read.

Probably the most important thing is you can tell if you are running the right prop or not. You don't want your motor over reving or lugging.
