service on an Optimax

I have bought mine Optimax with a few hours second hand.
I don't trust the man financialy that sold me this engine allthough he is known to be a great mechanic for these engines.

As prommised I will bring the machine back to him for 6 months extra warranty to see if everything is still ok.
At the same time I will have the machine serviced because my knowledge is not enough of this engine.

What I will do myself is:

Change the gearcase oil.
Change the sparks.

Could anyone tell me what has to be done more than this at 150 hours.
And most important, what should the normal costs be for servicing this engine at this time.

Any help would be welkom.

filters etc and seals, not sure on the details

sparkplugs run at around 100 per set i believe and take great care not to cross thread some of them as they go in at awkward angles, try marine power for a service manual for a bit more info, not sure how much use but is free

100 per set? Blimey... I think mine set me back a mere 48 from memory, anyway between 6-8 per hole.

check and poss replace every 100 hours but worth checking the condition of them as 2 strokers do eat plugs. the opti boys will comment on the reality of how often they have needed replacing in reality

Had our Opti serviced yesterday (105 Hrs) plugs cleaned and refitted, Guy commented that plugs in Opti's "Last for ever". Other thing involved in service is Belt condition and tension, oiling levels, waterpressure, engine running history, running temperature, compressor pressure all Checked by DDT. Service schedule says that impellor replacement after 3 years or if water pressure close to or below limits.

Out of interest how much did you pay. I paid around 180 for my first service.

Regards

Rich
