    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    Well, after a day in the barn,I think there is a reasonably happy ending! Thank you all for the suggestions. I bought the motor last fall, ran it once and realized I had some work to do. I think I was flummoxed because there were multiple issues... all the seals were original and completely...

    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    definitely a fan of seafoam, when it works! Much rather be fishing than tearing down a motor... The old 1963 Montgomery ward Sea King looks good on my 1963 Sears boat! Thanks for the timing video. Hadn't seen that- I'll save my 50 bucks for the timing tool and go that route! My motor is a 1963...

    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    Unfortunately, I didn't take photos as I went, and the lower unit is torn down again. At this I think I may be looking at a combination of things- *compression 80 in upper cyl, 85 in lower, so not great.- lot of carbon on pistons, etc. * gear case held 15psi, was able to create small leak at...

    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    Okay- here's the report- took a minute because I had to turn an adapter for the 3/8 machine thread on the lower unit to 1/8-27 npt to connect the vacuum pump... I was able to produce a small leak wiggling the shift rod. removing the bushing and o-ring for the shift rod I confirmed something I...

    Thanks for the tip. Pressure testing is all over the forums, but this is the first I've heard about vac testing. I'll give it a try and let you know what happened

    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    Just looked at my last post- The sheesh at the end wasn't a response to your post! I appreciate all thoughts. It was my frustration that the unit holds air but something is still leaking, poorly stated. Apologies. I may be dating myself, but I first used 2 cycle outboards in the early 70's...

    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    Hi, Thanks. Yup, replaced the shift o-ring. The oil was definitely gloppy gear oil, and lots of it. The only other observation I have that I left out is that it seemed to be leaking more after the engine was hot. May be that it simply took a while for me to notice the oil as it accumulated in...

    leaking lower unit, 1963 Gale Sea King (OMC) 15hp

    I am new to this forum, so hello. I am truly and most sincerely stumped. I have a 1963 Gale Sea King 15hp. I have completely disassembled the lower unit cleaned and re-assembled with all new Sierra seals. The original driveshaft seal was a single seal; the replacement is two seals that I...
