Re: outboard advice
Shell do a special oil for outboard gearboxes that comes in a bottle with a spout on it. It is usually recommended that you fill it from the bottom hole so that air escapes from the top hole as the oil is squeezed in .
You can run the motor in a water drum and observe that the telltale is emitting water which indicates that the impeller is ok. sometimes the telltale is salted up and can be cleaned by carefully poking a wire up the outlet. It would probably pay to order a new impeller as it will need replacing at some stage and it's usually better if you choose the time.
Remove the cover and wipe off any dirt and spray with WD40 paying particular attention to ay linkages you can get at.
The carb probably has a drain nut on the bottom , open this and let it empty, or, if you are feeling adventurous take off the float bowl and have a look at how clean it is. If there is a fuel filter in the line to the carb -replace it and if the fuel pump is accesssible strip it down to clean any gunge out of it.
Inspect the starter cord and replace if any wear is showing as it is good to know how to do this. If it is shorter than it should be it can be a sign of previous breakage as a result of being hard to start.
Replace the plugs and check the caps for cracks etc.
Check what the propellor shear pin is like and make sure you have a spare handy.
That should get you started, and also gives you a chance to become familiar with where everything is.
Happy motoring.

Buy this month's PBO. It contains an article on servicing outboards.

I have always used automotive oil in my Honda gearbox for over twenty years and the box is still running after something like two and a half thousand miles or more.
there is no sign of abnormal wear. Find the oil specification and match it to the automotive product of the same specification. To fill the gearbox, empty, clean and dry a lavatory cleaner bottle, the type that shoots under the rim, fill with the oil and squeeze into the filler hole. This should save you a few bob!
