So I want to remove the engine cover and look inside my new-to-me Evinrude 9.9 HP 4-stroke, but I can't. I can take the top cover off, but the lower cover is being a sumbeach.

On the back of the engine, under the grab handle on the inside there is a bolt I cannot reach.

Does anyone have a secret to removing this bolt? Its only purpose is to hold together the 2 halfs of the lower engine cover. it is below the grab handle on the inside of the cover, at the back of the engine. Below this there is a rubber bumper thinggie right where the 2 halfs of the cover come together. I suspect another fastener is hiding under there as well.

Figured it out - used a 8 mm extra deep and got to it. Now I have to track down a gasket for the valve cover and I think I'm all set.

With the engine cover off the next logical step was to check the oil filter. Damn thing wouldn't come off.

Being so very clever, I used the technique taught to me by the shadetree mechanic I apprenticed under in High School; back when pulling an engine looked like a fun thing to do. I drove a screwdriver though the sucker, and reefed on both sides until the filter turned. It actually bent the screwdriver.

I now have an oil filter with 4 holes through it, but it is no longer attached to the engine.

The local parts store doesn't stock marine oil filters. Arrrgh. It has a Bombardier part number on it. You think an ATV/Skidoo place would have one??

Glad you're improvising successfully--I think you're on your own!

I, unfortunately, have experience with a 1995-6 evinrude 9.9 4 stroke.

if yours is a similar year I can help. I even have a parts motor.

I liked the fuel effeciency and quiet running. I didn't like the over 125 lbs perched on the end of the boat, or trying to lugg it around.

the death knell for me was a $300+ powerpack CDI

parts are available and bombardier has parts diagrams online.

Thansk for the link Ken. The engine is heavy, but I didn't find it to be worlds heavier than the old 9.9 Evinrude 2 stroke I've been using. Maybe I should weigh it to see.

I'm just guessing at the weight. I had to add the longshaft parts to mine, and it seemed so heavy that I was reluctant to take it on and off the mount like I used to with the two strokes. (for theft prevention) I put two locks on it and hoped for the best.
it ran great for a year or so, and then began to develop a poor run condition that I chased as fuel related, but evntually was CDI unit.

I think suzuki made these for evinrude. that info didn't actually help me in any way so I'll pass it on to you...

good luck with yours, I may eventually buy that CDI unit for mine and put it back together as a short shaft for a jon boat.

I've gone to a similar era evinrude 2stroke on the Catalina and like it so far.

This is going to be more for long cruises (or for sale). I already have a very good 2-stroke Evinrude.

At lunch I found a guy with parts less than a block from my office, so that works well. I am guessing fuel injection/metering or some such thing? Do you know where a shop manual is available for thse things?

Just found the CDI online: http://www.outboardparts.com/mall/dynamic-results3.asp

Probably Capacitive Discharge Ignition.

If you ever need anything for Johnson, Evinrude, OMC call these guys. They've been in business since 1932 and have parts for almost any of the above vintage outboards. Take the time to read about their history. AND they are across town from where I live.
