Doing a rebuild of a mark IV 525SC and need a good book/ info to guide me through it, any recommendations?

Thanks

Get the Mercruiser Service manual. I think it is the HP3 manual. It will have all the specs.and instructions.

Your Checkbook...lol..
Chris

I thought this has incorrect information in it?

What about the seloc manual?

Seloc is an entry level manual.

I have all the OEM service manuals for Mercruiser including the 525 SC. also if needed I can provide all the OEM Service Bulletins per that engine application via engine serial number is needed. also if one knows the year model of the engine helps as well.

Thanks BUP,
It's Built in 1994, have not confirmed if it's a Gen 4 or 5 yet I need to check stamping.

Tried PM'ing you but your box is full, let me know when you've cleared some space and I'll send you the serial number for service bulletins.

Mercruiser says it takes Manual Number 848294-1

Thanks

some room currently for a PM. Can not say for how long thou.

If it's a '93 it's definitely a Gen IV. Fuel pump is mounted on the block. It's basically a GM L88. 9 to 1 comp, 4 bolt main, steel crank, 7/16 rods (dimple) and rect. heads. rebuild is pretty straight forward. Nothing trick to it. There's plenty more you could do in a rebuild for gobs of hp. It's all about the $$$$$. Any good automotive machine shop could do it. Any marine rebuilder will charge you double for the same work.

You wern't joking, it's full again, guess your popular

PM me a good email and I can send it to you there OR let me know when you've cleared some more room.

Thanks

^^^^ I know its common. If this was a board full of women I would take that as a huge positive. haha

Actually I do not mind, most of the PM's are about Fuel injector questions since I provide fuel injector flow testing and cleaning services.
