    Removing a 1988 Mariner 45 / Mercury Classic 50 powerhead Question.

    Thank You I believe the lower has two seals and an o-ring that gets replaced is there also a gasket?

    Removing a 1988 Mariner 45 / Mercury Classic 50 powerhead Question.

    Would removing the lower unit first be smart for reassembly of the powerhead? This is why I ask, the water pump tube and the shift shaft will need to be realigned when the powerhead is being reassembled sounds like a blind task I know with the powerhead on the mid shaft to align those two is...

    1988 Mariner 45 water mixed into cylinders 3&4........?

    Agreed that's the other possibility. But would the crank seal just contaminare the bottom two cylinders ? I guess I will find out. Thanks.

    Did that a few times in the last years and running premixed now......Mine is fine but I just don't think it's needed for the extra worry involved.

The boat is mine since new...

    Yes I see in the manual the baffle plate kind of isolates those two bottom cylinders a water jacket leak in that extended baffled area could be the problem. I will let you know what I find soon I hope.

    1988 Mariner 45 water mixed into cylinders 3&4........?

    Well I am stumped by only two cylinders at the bottom with the same problem ......do you know if the exhaust ports are separated 1&2 / 3&4 in the exhaust chamber? In other words can a water jacket leak on the exhaust side effect only two cylinders? Thank You

    1988 Mariner 45 water mixed into cylinders 3&4........?

    Since Cyl 3&4 are connected by the Transfer Port can water get into the these cylinders with a bad Transfer port gasket? Top Cylinders 1&2 are fine the bottom two have the same amount of moisture......any ideas? I guess this would be the same as the Mercury inline 4&6 cylinders. Thank You !
