[buggiedad_67]

86 glasstream with 120hp merc and alpha 1, put it into water after the bellow and bearing change, found it leaking where the exhaust hooks to transome, seal gone i know. but what i was wondering can this be changed whitout pulling motor out, or maybe the best way to put it is has anyone changed this seal without pulling motor. thanks guys richard

You have to pull the engine.

boy aint that the truth, i have looked for that seal part number and i guess i am just plain blind does anyone happen to have that part number, i have the elbow gasket number and i have already put new exhaust bellows on butsince i was pulling it i was going to go ahead and change the transome seal i found that part number, but just cant seem to find exhasut pipe seal.

Merc PN 41802

You have to look in the drive section and the gimbal housing for the seal. They call it an oring, but it's not round.

well pulled the engine today and when i removed the exhaust pipe guess what i found? three old head bolts one wedged up against the relief port and the other two just banging around, i wonder if that was the ghost noise i was looking for. so i got to looking and found the bottom two stud nuts a 1/2 in from being tight, then i found the four other bolts there loose, i check the showing wood and thank goodness i found no rot, who ever had rebuilt the engine i gusse had the transome plates off and forgot to tighten this stuff down, so while i am in there is there anything else i need to check before i put her back together. as i saying i have grown to like. you cant fix stupid.

If the wood is good, time for coats of epoxy.
check everything, including bolt holes.

went back out and looking things over and i found something i know just aint right, the rear mounts has what looks like a fiber ring, but it has two lock washers in the middle of that ring where the bolts go through i know that cant be right, is it???

Those "double wound" washers are correct.

i bought this boat used and i have found more things that were left undone and half way right, so when i found that i thought just one more to the list, however the man that own the bost was at the river the other day and he couldnt believe the differance in her she runs strong and quick, once i get all the jerry riggin done she should be a good boat.

Re: motor pull for leak?

If the NEW style Merc rear motor mounts were used, then no there is no double wound lock washer.
Here is a service bulletin and and installation instructions for the new mounts.
