Water Pressure Guage installation

[notarealone]

I can find all kinds of water pressure guages but none for the Yamaha V4 115. (Except through Yamaha $$$)<br />Is this a totally different type of unit than the others or will any pressure unit work? <br />Also, how do I install the connection fittings if I can use any pressure guage?

the connection is metric, the fitting is the top of the block on the port side. remove the 14mm hex bolt and red washer. the fitting comes in the yam kit. sometimes saltwater ones will bring the threads out with it.my adviuce is save the money and replace the pump everyother year, unless your running a jackplate or extreme engine heights.

you can put aftermarket gauges on you need part# MAR-WPRES-AD-TR it is an adapter for aftermarket gauges it has a nipple on the end of it you can attach it on port side head their is a plug that you can take out dont put it on the starboard side the cylinder sets to high and the tube hits the cowling

I have a book with a pic and a scanner but I cant figgure out how to move them. the adapter needs to be mated to the correct size tubing or the fitting will leak.
