Cheap hourmeters

[low277]

Has anyone put one of the cheap rectangular self powered hour meters / tachometers on a 3 - 4 cylinder outboard? I have one for my small generator, you just mount the unit and wrap the pickup wire around the spark plug wire.

I wasn't sure if they would read correctly on multi-cylinder engines.

Thanks

It is an inductive meter, as long as the lead is wrapped around only one plug wire it will only read one ignition cycle. It will work just fine for single or multi cylinder engines.

I know there are some that you can change a few settings in such as the Tiny Tach. Some outboards may not read the correct RPM's due to the firing order of the plugs and/or how often they fire.

I just picked up one made by Hardline and will be throwing it on my Yamaha 25 4 stroke.

A few years ago I had a dealer put an hour meter in one of the blank gage holes in the dash. It works well, I am not sure where it is wired in to but it is so NOISY!!! When you are trolling it drives most of my fishing partners crazy, Its mine so I have to put up with it.
