best manual for Mariah 21 SC 1998
 

I have a Mariah 21 SC 1998
with a 5 ltr Mercury Marine engine
I think the serial no. is OLO45852
What would be the best manual to purchase
which would give me details and views of this engine along with service details

Did you check in the manuals section of the forum? We should have what you need in there.

Colin, we have the manuals online. Since you are a contributor, you have access to them. We have the service and the engine manuals that you need. In the "Engine Maintenance & Repairs" section, click the blue section called "Service Repair & Operating Manuals", then click "Mercury Mercruiser".

Hi and thanks for your reply
The reason for needing exploded detail of engine is
Whilst at sea travelling at a fair rate of knots smoke started coming from all over
In my panic I cut the engine whilst still in gear
I was rescued and am now back on my mooring
I am unable to get engine out of gear. My initial investigation I could not smell any motors that could have burnt out and there is no sign of burnt out wiring up to now
The engine manuals I am looking for are in relation to
my Mariah 21SC with the following engine
