I just bought this boat motor combo, I ran the motor and the tell tail dosnt seem right, replaced the thermostats, they look bad. replaced the empeller, looking okay changed both fuel filters no water and gas looked good. still at over 4000 rpm the tell tail stream cuts in and out. did a compression check all are between 120 and 122. the SR is OT630735 its an 150XL on the back of a 2003 212 hydra sport CC.
