Anyone got an idea why our 200XS GEN II is running really rich and burning twice as much oil and fuel as the other boats running with the same motor? We are also around 700rpm down as well, the boat has been put on diagnostics and all the test carried out are spot on which seem strange to me !
mercs had a problem with coils,they were working but not giving enough spark so not burning fuel properly,change the coils for the latest part no and you will find big difference,thats why you will not pick up fault on ddt,
