Hi all,

Just bought my first boat - 23ft Larson with a 5.7 Mercruiser Sterndrive. The owner has given me a PDF manual number 24, but it is dated October 1999. The DOM on the engine is May 2007 & Serial number is 1A050740.

Is this the correct manual or do I need to get another (and where from)?

Also I hear one that a potential problem could be the exhaust manifolds if they have not been replaced in some time / at all? Id this something I should consider as part of a preventative maintanence thing? FYI the boat is berthed in sea water in a hot climate (although has been on and off a trailer for the last 5 years).

Cheers everyone!

The engine uses several manuals. 31, 36, 37, and 40
You can find them here. http://boatinfo.no/lib/library.html

You could also order the newest #31 manual that includes 37 and 40 from any Mercruiser dealer, 36 has not changed.
