Tachometer for Yanmar 1GM10

I was thinking about tachometer for Yanmar 1GM10. The original option of Yanmar were way too expensive, at least the stuff which I found in the net were above 200 euro. The cheap options like normal tachometers which one could find in the shops have to be connected to the alternator. The Yanmar 1GM10 does not have such an output and an extra cable have to be soldered. The Tiny-Tach is a great alternative. Simply you attach the transducer to the fuel pipe inlet, and it is basically plug and play. I went for their device for diesel engines Diesel Tiny-Tach. Looks good, and indeed it is tiny :) I ordered it directly from the US shop it arrived in the Netherlands less than a week after the order was placed. The price including the delivery was about 95 euro.

Uses a transducer on the fuel line which must be the correct size for the line-6mm, 7mm, 1/4.

it is tiny indeed :)
