    2004 Merc 2 stroke 90HP seized after rebuild

    did you thoroughly clean the block after getting it from the machine shop? or just get it and start assembling? Normally it takes about 25 minutes of washing going into each and every passage with pressurized water, dawn dish soap and a variety of scrub brushes and pipe cleaners.

    Totally baffling !!! Impeller replaced !! And not pumping

    stop trying to pump water from a tote. if it works, you are lucky. these pumps are flood to prime, meaning the water level must be 6" or more above the impeller or use muffs. to get water 6" or more above the impeller, the boat must be in a tote big enough to get the drives submerged.
