hello all. i have a 98 mariner 200 efi. been having bogging issues when i thought was just when it was cold. what i was normally doing was while loading my gear and stuff on boat i would have it running.so normally it would be running about 10 minutes and when left dock and short distance away id gun it, it would act normal no bogging. so pretty much this year that is how it went every time. other day i was planning on going out when wife got home from church. so this time i was waiting on her to get home and decided to do something different. didnt think it would make any difference.started motor up before she got home to warm it up and after 15 minutes i shut it off.it sat until she got home and we were ready to leave which was like 20 minutes after i shut it down. temperture gauge was still reading same that it was warmed up. and down bayou a ways where i can gun it i did and it just bogged. so i figured it didnt have to be warm to not bogg down it just had to be running for awhile to not bogg i guess. ANYBODY HAVE ANY IDEAS WHY THIS IS HAPPENING? I CHECKED ALL ELECTRICAL WITH DVA METER AND EVERYTHING CHECKED GOOD. REPLACED ALL FUEL LINES AND FILTERS. CLEANED FINAL FILTER AND REBUILT MANUAL FUEL PUMP. crazy to me! before use to bogg bunch different times through out the day when out fishing. noticed rectifiers were charging like 18 volts and changed them out. then it only bogged when first left the dock and if i sat few hours on a sand bar. checked tps and everytime checks good. please anybody help abrother out. thanks in advance ted
