Re: ’67 100 hp electric shift wiring to lower unit removal

[Don]

This can be a tricky operation indeed, especially on a salt water engine, sometimes these harnesses get packed in tight with salt where they come through the inner exhaust housing where they come through into the lower cowl. You have to pull down hard enough to pull the harness through, but know when to abort the attempt to avoid ripping the stuck harness apart. Is this a fresh or salt water motor?
Admittedly, I have never actually done a water pump job on the unique gearcase setup on one of these old 100hp engines. But, now that I think about it, I seem to remember watching another technician pull the gearcase down with the extension housing attached to it. In other words, remove any external bolts holding the extension housing to the exhaust housing and pull the gearcase and extension housing down together.
Hold off on further attempts while I look to see if I have a manual for an old 100hp, perhaps someone else has a book and can look as well.
