i bought this boat/motor new, never had problem til other day--only use it once, twice a year for last few years. took it out, it cranked relatively quick, ran about 100 yards fine, then alarm came on. shut it off. not pumping water. trolled in emotor. took it to local merc/skeeter dealer to replace water pump.they did. then said it was also not firing all cylinders, only one.needed "trigger" $150. replaced "trigger".Said still not firing all cylinders, now firing 2+3 but not #1. Needed "power pack"(or "switchbox assembly").$250.I held them up on this til i find out more from somebody out there in cyber land! My total bill will be apprx $730 if they do this!(and all for a water impeller!) They also said they changed the lower unit lub-was milky with water. I had just changed it the day before. The fluid I drained was fine, and the new fluid was only in water for 10 minutes, and 100 yards. I did not put new gaskets on the plugs, they said that is where it leaked. (?) Any thoughts?
