1962 Evinrude 40 hp oil leak

[Merrill]

I have a 1962 Evinrude that has developed an oil leak. The oil is comming from a weep hole about 3" above the prop on the righ side. I have a nice shop and tools, I would like to fix it myself. Any advice and/or part numbers would be welcome. Thanks!

I think you are looking at unburned fuel/oil leaking out of the exhaust housing. Normal.<br /><br />If your lower unit fluid is clean and not milky-no worries.<br /><br />You may want to do this.<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=36;t=000016

The weep hole I'm refering to is about 1/4 inch in size. The fluid leaking is close to black. Thanks

I just checked the gear oil and it's still full. I think the problem is the carb weeping a little gas and washing a little grease down to that weep hole. I have a carb kit on order, should be here tomorrow. The gas seems to be leaking from the unit next to the carb that has the lean/rich (choke?) writing on it. Hope the kit includes those gaskets as well.

All the exhaust runs out through the lower unit, and a lot of unburnt fuel/oil (especially with a 24:1 mix) comes out various weep holes in the lower unit. It gets black from washing carbon out of the midsection on it's way down. All two-stroke engines will do this especially if it's been idled a while.<br /><br />If you look on your engine block, in the front but way down there's a little panel held on by two screws. That's a valve that's designed to take fuel/oil which puddles in various spots inside the engine and dump it down the leg. It comes out pretty much just next to the driveshaft inside the midsection.<br /><br />The carb kit has gaskets and such for every part of the carb, including the rich/lean knob packing.
