need information on replacing impeller on a 1998 mercury 90hp outboard . it sat for a year before i bought it, ran it 3 times so far pulled up to a sandy shore and noticed it didnt seem to be peeing from motor as good as before. no heat warnings or anything, the water coming out is not spraying out as far, but is not hot just slightly warm,someone said the thermostat might be hanging due to sand. anyway if anyone has some info on if its a big job to replace or if it easy please let me know. thanks
