[QUOTE="JaguarJim, post: 412610, member: 20785"] Hey bud have been having same kind of issues with my 3cyl 25 Johnson, you can usually tell if the switch box is acting up on these motors because either the quickstart doesn't activate on startup or never shuts off leaving it on high idle, unfortunately there is no way to test these packs, and new OEM one will set you back almost 500, optical timer base isn't cheap either. I've changed carb parts, rebuilt fuel pumps, even changed all fuel lines through out, and reset idle needles on mine, helped a little, but still wanting to die after restart and running down the lake. If you have service manual, go through it, and look at the idle sync section make sure all that stuff is set correctly, mine wasn't and mine was installed by an OMC/BRP dealer who should've known better, that was bought to my attention by some other members on here, that I needed to check that stuff before proceeding, it helped a bit, but I too am in suspect of the switchbox now. On these motors they are notorious for going bad, the newer version of box after 1999 is supposed to be better, but have heard of guys burning newer ones up too. [/QUOTE]
