Re: Coolent???

It could be. or a system could be optional. I have a 898 and a monitor full FWC system was put on it.

I believe I saw a pic in the clymers manual with a FWC system and a raw system for the 79 898.

Do you have a heat exchanger(cylinder with coolant lines attached to it and a pressure cap, like on a radiator)?
NO - then you have raw water cooling
YES - then you have fresh water cooling
If yes, is it a half or full system?
you will have to determine (by looking at the cooling hoses) if your manifolds are cooled by the coolant mixture or sea water.

The first thing you will need if you plan on doing any of your own work is the Mercruiser Factory Service Manual. Clymers and Seloc DO NOT count, check ebay, you can get them pretty cheap there.
