I am hardly familiar with boats, much less the Mercruiser I/O of any kind.
Looking over a recently purchased Stingray, (17'), I noticed it had a closed cooling system.
There is a heat exchanger low on the engine on the starboard side.
I'd like to throw out some basic questions on this I/O/
1. Did all the 3.7 Ltr.'s have a closed cooling system?
2. Is this configuration desirable?
3. Are there any downsides to the 3.7 Ltr 4-cylinder? (That's a lot of liters for a 4-cylinder).
4. Are there any common problems associated with the 3.7 Ltr. and/or This type stern drive?
5. What should I look for?
6. The coolant reservoir looks like it has near 100% anti-freeze in it. How is the heat exchanger winterized?
Thanks.
P.S. I may not be able to respond for a day or so, but replies and comments will be read.
Applicable ones will be replied to.
