Tachometer recommendations

On the Mycron 3 or 4, how do you pick up an rpm siginal?

wire

They use an insolated wire that loops through a connection on the back. you take the wire to your spark plug wire using a clip that is provided. you can replace the factory wire if you need it longer then what is provided.

I am fairly sure that they use wires which means you have to special order longer ones since a boat is a wee bit longer than a go-Kart

Hi Mike, on the RPM no special wire. I don't remember off the top of my head what size but its just auto electrical wire. If your wire gets so long that you are not getting a good signal for the rpm, you can wrap it around the spark plug wire a time or two to boost the input signal.

Well I hope this info help Tytruly.

I found it and I had trouble cause it is spelled Mychron 4. I checked them out and they are made for Karting and are $680 for the basic version.

I also checked out another place called Digatron and they have a DT31 tach version for $230 but I contacted them a couple years ago and they said they would not work on our outboards. I don't know why but thats what they said.

thats BS, I have had Digitrons for 10yrs now and they all work fine on my motors (OMC, Merc, Yamato, Tohatsu)..................DIGITRON even sponsored a SLORA racer in the past....

Can any of these Tachs be hardwired to the ignition system or do they all get wrapped around a plug wire?

The reason why the mycron is such a good tach. After you take a run, you can go back and review the whole run and see what your rpm was as you were running. So the turn shows it going down some and then the straightaway you see how your rpm gains. You might have a high speed reading for a prop but the rpm is way down in the corner. As long as you take a test run the same every time you will see what each prop is doing. We run the same lap every time. The prop makers like this info if your having them rework your props also. Its worth the investment!!!! Mikey

Great info Mike, really points out the true "value" of a good tach. Looks like I need to upgrade.

I know that Craig Dewald wants tach readings at the end of the strait and exit of the corner to make good accurate prop changes.

Has anyone tried the Mychron 4 on a Y-80?

[17W]

Yup!

Donny Allen does.

Digatron.....DT-6E

Works great on pointed ignitions. The newer models work on the electronic ignitions.

They are out of the great Northwest. Google them and talk to someone who knows powerboats!

I have tried half a dozen tiny tachs and they all break or don't work at all. And yes the Micron is cool but not always user friendly!.........

Matt once you master programing the VCR this thing is a snap!!!!!
