I've found it doesn't matter, none of the gauges work anyway except the trim. Oh yeah the speedometer does go up to 20 when I'm runnin about 50
On my 1987 Nitro (pre-BPS model), I have no speedometer,no trim gauge,intermittent fuel gauge and working tach.
Most of the labels are long gone.
But it still catches fish and no payments for a long time.
