Good evening all, I have a pair of 525SC, built in 1992 and redone recently, both units have Mercruiser Rev Limit Ignition by Firepower and one of my units has gone bad, I have swapped the unit between both engines and the problem follows the unit, does anyone know if these can be rebuilt or does anyone have a used one for sale, I believe the unit is set at 5400 RPM,
Thanks in advance
