I'm baaaack.
After 30-40 good hours with the 1993 Force 150 I repaired earlier this year, I noticed two symptoms of trouble last weekend. First, it was down on power and second, it was hard to start (as if the starter/battery were too weak to turn it over at full speed). I pulled the boat out today and ran some tests. Here's what I have so far.

- My battery charger says the battery is fully charged.
- Compression test shows near zero compression on cylinder #4.
- The spark plug from cylinder #4 is washed clean like new.
- A small spray of water appeared to come from cylinder #4 when I turned the engine over to test the other cylinders.
- The head bolts were still torqued to factory specs.
