Helping out another boater. Boat was running great with no issues. Yesterday while on water the boat would stalll when plAced in gear. I disconnected the shift interrupter wire and it would not stall when placed in gear so he was able to drive back to the dock. Question . is there Any quick diagnosis for the cable or interrupted since we are in northern Michigan and no were near my manuals and reference material , and Internet is limited up here lol.. The only info on boat rt now is a 85 merc 350 with alpha one drive can get more if needed . It does have the older style roller interrupter assemble . Thanks
