Hi trev,

Doug ashley marine (other side of the bridge to us at st olaves) might be able to give some advice as I know he is a mercruiser specialist. He did our BSS on jupes and was very helpful with other technical stuff, though I am sure you will find someone on here with invaluable "free" advice :naughty::naughty::naughty:

Isn't that the same lump fitted to Volvo cars like the old 760? perhaps there may be a resource on one of the car forums.

Probably not, as Mercruiser have been tied to General Motors for many years, more likely a Cummins engine and not a volvo! cheersbar

Derek, have a look at this site as if you scroll down there are many service manuals for the 3.7 lt Mercruiser engines in .pdf format and all free


(170/180/190 engine blocks essentially the same but you may be able to find a more specific reference

Scroll to the bottom of the page and you will find many .pdf reference and service manuals.. Also have a search on the site and you may find exactly the original service manual for your engines
