1998 Maxum 2800 scr
Been wanting to change out my gauges as the old ones were cracked, needle jumping around all the time, and just not that attractive.
The slight problem was that the old gauges were mounted from the inside and flush (basically no lip on gauge to cover the opening).
the larger tach and speedometer had a 4" hole. almost all gauge options require a 3 1/2" hole unless I go with oversized gauges and I felt like 5" was just big for my dash.
the smaller stock gauges had a 1 3/4" hole and almost all available require 2 1/16" hole.
since the larger ones had too big of any opening I had two stainless rings from a machinist buddy. 4 7/16"OD and 3 1/2" ID.
the smaller holes needed a larger to 2 1/16". I got the 2 1/16" hole saw and drilled a hole in a piece of 3/4" plywood that was approx 3" x 3". now I had a piliot to enlarged the opening. I taped the jig over the hole with 2 faced masking tape and also held it with my hand. if that ply slips just a bit I basically trash the dash. the dash is actually metal with the woodgrain laminate of some type on top.
the original gauges are made by Faria so I purchase the same manufactuer in a different style (Faria Kronos). This way the sending units wouldn't have to be changed and the wiring just plugging right on like the old ones.Nice upgrade and a pretty easy project.
found the gauge set on ebay for $79 and they are in perfect condition so that was a deal.
