How often to Service

I have a mariner 30 hp 2-stroke which was serviced last year (140). I then used it in Cornwall for around 15 hrs, flushed etc after each use. Drained fuel at end of season, and sprayed fogging oil into cylinder. Started it today and runs great. Question is should I get it serviced again or should it be ok to take as is down to Cornwall for another 2-3 days of boating. Is there anything else I can do as a minimum?

Also had a new de-graff trailer which was used to take boat to Cornwall and launch in and out of sea through deep sand etc. washed down after use etc. Question is should I replace hub bearings before trailering down to Cornwall again?

Any thoughts would be greatly appreciated.

Hi

You could put new spark plugs in or keep as spares.

Good idea - what's your thoughts about the trailer bearings?

Have you spun the wheels? Do the bearings rumble? What state is the grease?

Personally, I'd strip, clean, check, replace as necessary then repack with suitable grease.

Thanks for replies. It's a fair distance to Cornwall so will take your advice and strip the hubs etc next weekend.

The engine will be fine. Echo what others have suggested regards regards new sparks. If it's a pull-start, extend the starter cord and check condition. If in any doubt, then replace.

Re the sparks - if I order spark plugs for the outboard will they have the correct gap or will I need to adjust them? Anyone recommend a good place to order them from.
