Re: 60's 33hp Evinrude with Oily Spark Plugs
Shouldn't be a different gas fitting if it's a 33hp. Ought to be the same as any modern OMC outboard. Unless you're older Evinrude has a 2-line pressure tank.<br />You can use any single line outboard tank; just get a cheap OMC fuel connector and a couple hose clamps from Canadian Tire. Remove whatever fitting you've got and fit the OMC one.<br /><br />If you can't get a running test, check the compression (both plugs out, 90psi ok, 100 good, 110 very good by my gauge). Run the compression check twice because it may be thrown off by any fogging oil he may have used to store the engine. There should be no more than a 10% variance between cylinders. If pulling, give it four or five good strong pulls for each check.<br /><br />Look for signs of overheat, like burnt paint or scorch marks particularly on the head (where the spark plugs screw in).<br /><br />Check spark (plugs out to make it easier). Should be able to draw about a 1/4" long arc on that engine. This is a frequent trouble spot, but it's fairly easily & inexpensively fixed if you're handy with wrenches and such. Often the trouble turns up as a spark that won't jump more than about 1/8".<br /><br />Check a bit of the lower unit oil. Black bad smelling stuff with metallic dust in it is actually ok (just neglected). Milky like coffee with cream means water is leaking into it (but a little hazy is rather normal). Clear stuff was recently changed. Peices of metal you can feel is very bad.<br /><br />As with any outboard, ask when the water pump impeller was last changed. If it's been a a couple years, plan on changing it yourself. If he doesn't know, the engine's been neglected.<br /><br />Check the condition of the rubber isolators you can see.
