Murphy has been rough on me today. Yesterday I lost a nut in the grass. Not even a magnet would find it.
I noticed the new to me 1977 Evinrude 9.9 outboard wasnt idling properly so I decided to stick it in the tank and figure it out today. after re-gapping the plugs, running some sea foam, and carb cleaner (and making a huge adjustment to the idle mix knob) I had it purring at ldle like it should.
I noticed some oil in the tank but assumed it was unburnt 2 cycle due to running rich. Nope. Dropped the water in the tank and the prop was COVERED in grey gear oil. All around the outside, and tons collected inside the prop hub. Spun out the gearbox drain and sure enough, grey oil.
I think its probably the prop shaft seal given how its all coming out around the prop. And possibly a bearing since it feels gritty as I spin it by hand. Somebody else also suggested the upper crankshaft seal. I THINK I can tackle it as it looks pretty easy at least to get the lower off after watching a howto on an impeller replacement. But wanting to get an idea what a pro would charge in case it might be worth my while to leave it to an expert instead of teaching my kids a handful of new swear words.
And avoiding the big shops if possible as they have more overhead than smaller shops.
Suggestions?
