| | RE: Johnson SLOW mode bypass?
If you want to disconnect the SLOW sensors, disconnect the tan/blue leads off the port and starboard temperature switches. As far as SLOW goes, it only kicks in if the temperature exceeds 240 degrees.
One thing you have to consider is that the carbs on that engine have three circuits, low, intermediate and high speed. One question I would pose is, Did you perform a link and sync on the carbs? The low speed jet is adjustable and the others are preset orifices. You have to make sure that the orifices are clear. If you adjust the carbs, make sure that you have it in the water with proper back pressure. A low idle speed can also cause it to stall on acceleration. The initial setting for those carbs is 3 turns out. Then you'll have to fine tune them. Hope this helps. Good luck.
Work is that annoying time between
