Installing Gauges?????

[gstanford85]

I have an 1975 evinrude hustler 75hp and want to put at least a tach,oil press,water temp, and tilt gauges on it. If this was a sbc I would have no problem doing this but boats are foreign to me. I was also wanting to put a speedo on the boat. Any advise on what gauges will work what won't, and most importantly how to do it would be greatly appreciated. Thank you in advance.
