The noise of the E-Tec comes from direct injection, and at some RPMs direct-injection engines (autos too) are noisier than non- DI engines. It's the price to pay for more efficient combustion.
Once the E-tec is broken in there will be zero visible smoke, except for a slight amount for a minute or two from seasonal storage. It's the motor to have if you don't want to asphyxiate water skiiers in the water near your boat!

In terms of EPA measured emissions, the E-tec runs cleaner than most 4-strokes, and has a superior lubrication system (dry sump, scavenging) to them, although they are catching up.
Matt- I keep a 1 litre plastic container of oil 3/4 full as a spare. As you screw the lid down, squeeze the bottle at the same time. Stop turning the lid when the air stops coming out. Any looser, or tighter than this and you won't have a good seal. Now you have a partially-collapsed plastic bottle that, initially at least, wants to suck air into it, instead of spew oil out, if it does happen to spring a leak.
Find a plastic oil bottle that you know doesn't leak (some do) to use. Find a good one in the store (smaller cap better in this case, if the threads are solid), use the oil, and save the bottle for this purpose. Make sure that remnants of the discarded cardboard seal don't interfere with sealing of the cap.
Then I take an old heavy sock and put the bottle into that, fold the top of the sock over again so you have a double layer, and put the whole thing in a heavy (5 or 6 mil) plastic bag (a Ziploc freezer bag or similar will do) and label it. If you do use it, the sock rag is already handy so you won't get oil on your hands, and can wipe up any drips. Or you could wrap the sock around the oil reservoir neck to soak up any drips if filling it in rough seas.
Lean or secure this upright at the back of the boat inside near the stern, because with an E-tec you're never going to use it

(and it's very stable and has a very long shelf life). In 10-20 years a future owner cleaning out the boat will discover it.
