It turns out that the issue I had with the counter rotation 140 was because of a pinched wire running under the power pack, the new engine wiring harness has longer leads up there that caused one wire to end up against one of the mounting studs . This caused the alarm horn to go off and it go into limp mode a couple times. The front bilge pump hose had a bunch of perfectly rolled up leaves clogging it, most likely from some type of wasp or bee nesting in it when the boat sat for a couple years. The hose developed a leak and was very brittle, but now is replaced with a new one. Standard rotation 140 has a tach that works intermittently, could be wire connection or even the stator. I'll just keep solving them as they come, normal stuff for a 30 year old boat I guess.
