'88 Merccruiser exploded view

[sharpesh00ter]

Hey All,

I'm looking for a labelled exploded view of an 1988 Merc Cruiser 3.0. I'm having some overheating issues and don't know what I'm looking at when I try to troubleshoot it.
I'm looking for the water pickup pump and thermostat for starters.

Thanks

And this may help as well. Just scroll down to your '88 3.0, open the index and choose your flavor.

Ayuh,... The raw water pump is in the lower unit, the T-stat is in the T-stat housing, top front of the motor...

Here is how you change the raw water pump impeller on your outdrive.

You guys are a buzz kill! Wish someone would have mentioned the back flush earlier. Oh well back to work on it I guess.
