If I was more confident about these things I would do the same. I guess it depends on how handy you are!

I think as long as you start with simple jobs, you learn and progress. For example my little 4hp mariner wasn't running right. Got told it was probably a dirty carb. I went straight in at te deep end by removing the carb, stripping and cleaning it. Only problem was I ruptured the gaskets causing an air leak. I learn from that. To be more careful. I still only know minimal things about engines, but youtube videos help me out loads, going through it step by step. Try it, might surprise yourself

A simple service of a carbed 2 stroke isn't rocket science. If something needs fixed or adjusted then it's a bit more complicated. I did my wee 9.8 and it was very handy.

Get a manual and read it
Get the parts
Get a gear lube pump kit
Get new gear box screw seals/washers
Use the right grease
Be gentle with stuff...

The first service might cost you as much as a "shop" job, but you will learn soooo much and the next service will cost you buttons.

I had a very nasty experience of so called 'expert' marine engineers destroying a perfectly good engine so I won't be either using or recommending them but you have to accept that most of these guys are working on marine engines every day & have the best equipment & knowledge to pick up potential problems !!! Let's face it NOBODY wants a breakdown at sea. We never worried too much in the Lake District when all it meant was a lot of paddling to shore, a little different in the sea when your life & that of others might depend on it !!
Part of the fun of owning a boat for me is working on it & most jobs are fairly straight forward if you have the tools plus there's a wealth of information on t'internet.....

Why?

Because you may be "tooling up" for the job. A lot of the consumables are cheap in bulk but will do many services. Do you have proper marine rated grease? Prop pins? block spray?

FYI, check the plugs before you bin them, they may be fine or be of use as a backup set.

Don't forget to check/replace the pull start rope (if you have one).

Sounds ok?
The fuel filter reservoir on the engine can be cleaned, rather than replacing. Simply disconnect, rinse the mesh filter with a little methylated spirit, ditching any petrol in the reservoir, then reconnect. Prime the fuel bulb to get the petrol through the system. External water/fuel filters are a different story and need to be replaced annually.

Only thing I'd add is to replace the start cord/rope. I had a Yammie 25hp starter cord break on me and had to get a salmon fish farm boat tow me in. Replaced the cord every other year there after.

A suggestion - replace it before it appears to need it. You then have a spare AND you know how to fit it
