Need some advise on new guages

[MRBM237]

I am repowering my 97 21' Tracker fishing barge with a 2000 Yamaha 90 2-stroke (TLRY) I love these gauges on ebay...

I see they are for 2001 and newer and also they are for 4/6/8 Cyl motors which I do not have mine is a 3 cyl. I don't care about the speedometer but I want the tach with the trim and fuel, oil, temp, volts and also I want to add a water pressure gauge that matches. What is the difference why these wont work on my engine and what do I need to look for when getting gauges for this motor. Thanks for any help.

IDK if they will work but they sure are nice. I know you need to add a fitting for the water pressure gauge hose to connect to, at the top of the block.

If you know how to hook all the the gauges up your smarter than I am. I would check here, this might help.
