Water Pressure Gauge.

I have one on order. Nothing in my manual shows where to hook it up, so where do it go? 115 Yamaha 4 stroke.

I've got a 60HP Yammie 4 stroke and installed it myself. Was in the same situation as you and couldn't find anything about it in the manual nor the internet. Ended up taking it to a dealer for 30 hour service and while there picking it up, popped the cowling and asked the mechanic to show me what and where. Basically on the port side of the block, there is a plug fitting that you remove and install a different fitting with a nipple that connects to the hose. Wasn't much fun snaking the line through the rubber grommit where the other cables/wires come out of the front of the motor. Other than that, it was a snap. I could pop my cowl and snap a pic for ya if you like. Probably not much difference in the location even with the different size of our motors. Mine's an 06 model BTW. Shoot me a PM if you want that pic. Don't check here often.

Since Wannabe is gettin all nautical :D

my 90 was on starboard side, a touch aft and below the oil filter.
Hex-headed plug with a fiber washer under the head, somewhere abouts
a 13 or 15 mm wrench fit it. Had to replace it with a different, longer one with a female pipe
thread in the head of it, nipple screwed into that.
It was oriented long-ways with the boat, other words the flat portion of
the bolt head was facing forward. The special bolt did not come with the kit, said
to get it from the dealer so mine is Jeffro-built outta a piece of
stainless.

Ditto on snaking the
rubber hose thru, my worst part was fishing it through parts of the boat...

p.s. my gage instructions did not have any Yamaha illustrations, but did
have one for older Mercury 4 stroke that was just like mine.

I like them tools with whole numbers on them. I know 11 is littler than 12, etc.

Never could understand why a 16/32 was different from a 1/2........

We are becoming a gadget dependent country. Looks like cursive writing may be a thing of the past.

Wonder how folks will sign their checks? Text message? My o my.

What checks? Mine go staight to the bank. I never see them. I agree tho about the metric system. So much simpler.
