I was assured by Simpsons that there was no 20 hour service on the Optimax and that the first service would be at 100 hours. I hope this is the case, after all the discussion on here about service intervals with different engines.
They told me that the onboard computer will automatically adjust the oil consumption after it had been run in.
Well, sorry mate, but rest assured it does have a 20 hour service, i'll go and dig up the info. from the Merc website for you, but just to be certain, ring Tim Bennet, he was very helpful when I phoned and he may bend the rules (and put it in a letter) if there is a problem, like he did with me, although the rule bending in my case was because an error they made.
Heres a direct link to the service log book http://www.brunswickmarineemea.com/filereader/file/pdf/4/enen/outboard/2008/logbook/889158r02.pdf

Rest assured of one thing, what main dealers tend to say and what the manufacturers stipulate, differ greatly, I spoke to 4 different Mercury Authorsed Dealers and had arguments with them all regarding required service intervals, to the point that Barrus sent out paperwork to all 4 of them, telling them what the situation was, all 4 of those dealers insisted I must have a 20 hour service, as has ALWAYS been the case, BUT not in my case, due to a paperwork error with a Barrus backed 5 year warranty, which ceased to exist in August 2008 when Mercury took over the 5 year warranty themselves.
