Just changed the oil after 1 hour of run time on the new Suzuki 2.5. I panned the oil back and forth in the sun and you can most definitely see extremely fine particles of metal.
I'm a bit skeptical of the 3,000 miles or 3 months oil change schedule for automobiles . . . but changing oil during new engine break-in - you can see truly the need.
I recently changed the oil in our Tohatsu, it had about 11 hours on it (the manual says to change it at 10 I believe). The boat was still on the trailer so the engine was over my head, so I figured it would be pretty easy to do. I warmed up the engine for about 10-15 minutes so the oil would flow better, got a container to catch the oil in, and a funnel to direct it there. Got everything ready, unscrewed the bolt, and the oil shot right over the top of the funnel into my face, down my shirt, and onto my pants. I'm wearing that shirt right now, and after a number of washings and soaking in laundry detergent and Oxyclean, it still smells faintly of oil and the stain is visible if you know what you're looking for.
Lesson learned, use a bigger funnel with a splash guard at the back!
Note: The fuel filter is an inline straw and is a pain to get to .
I had to remove the carb, two screws, loosen the hose clamps and remove the fuel control valve that exits out of the base of the engine pan.
In my case, I also cleaned out the fuel tank as I saw grot inside. To do that, I had to remove the pull start (3 bolts). That's when I found the fuel filter was inside the tube between the fuel control valve and the fuel tank.
I think I'll make a habit of putting a paper towel as a strainer when I refuel the outboard when practical. It was the blocked fuel hose that prevented the engine startiing. I figured that out by blasting engine starter in the intake and the engine would run for a second or two.
After cleaning the tank, filter and carb, I added fuel stabil to the tank with gas. Started easy

Other than being a little cold blooded, i.e., takes a while to warm up, it's a great little motor. 30 Ibs, when you shut off the fuel to the carb and the fuel tank vent it doesn't leak at all. When towing the dinghy it also has a tilt position.

Haha funny guy. Actually you can make a pretty nice, oily mess when you forget to put the dipstick back in <i>before</i> you start it back up after changing the oil. That just wasn't my day.
