I have a 50 hp 4 stroke on the back of my rib which is 3 years old and done 40 hours. I would like to service it.
Could you advise if this is possible, advisable for a amateur mechanic? Also is there anywhere I can download a service requirement check list.
Thanks
 
It would help if you give the make and model of the engine. To service a 50hp four stroke outboard should be quite simple. Plugs, water pump impeller, gear oil and anything that doesn't look right.

Maybe someone else can correct this.
 
And engine oil and filter. Check timing belt carefully, although 40 hrs is nothing.

Maybe time to do tappets too, check service schedule..

Lubricate linkages, steering system (if remote..) tilt and trim mechanism etc.

Check / change anodes.

All simple stuff, easily DIYable. Allow a day if it's your first one, impeller can be tricky.

Is there a manual available, something similar to the Haynes books for car servicing ?
 
Yamaha will do a service / workshop manual, but I don't have a copy, sorry.

A generic engine course would suffice if you've never driven a screwdriver before. RYA do them, others are available.

None of the above is really that difficult, the hardest bit is separating / reattaching the lower leg to change the impeller. Again, you don't need a degree in spanner work to do it, but you have to get the drive shaft / gear change mechanism / water pick up pipe to line up perfectly on reassembly, which can be fiddly.

It all sounds easy until you get to the last bit! Maybe that's why we use people like you with experience to do it. What would a ball park figure be to do a service (straightforward, no problems) ?
 
Hmm, difficult, mainly cos I don't know the labour rate in the Algarve!!

Budget on four hours labour (high side maybe..) to cover any awkward bits, + parts. Someone experienced in your particular engine could probably do it in two hours though.

Many establishments will quote a fixed price service as well. A three year old engine shouldn't throw up any really nasty surprises, Yamaha are a very good manufacturer and the engine will be well built and should come apart relatively easily.

Older neglected engines are harder, as bits corrode and weld themselves together.
