Hello. Great forum here...tons of good information...long time reader first time poster.
I have a 1997 Regal Destiny 200 20' center console boat powered by a Volvo 4.3GL PLKD with 450 hours. At the end of May I took some family out fishing on the grass flats in the Gulf of Mexico. While cruising the flats the engine overheated. I shifted to neutral and turned the key to off but the boat dieseled for about 30-45 seconds before finally dying. Waiting for engine to cool and tried to start but started would just spin...would not engage flywheel. Called Seatow and got pulled in. At that time my mother (who had moved in with us some years before) was dying of liver cancer and I was her full-time caregiver till she passed June 29th. Now some 3 months later I'm starting to feel like I want to get back to life again and realized I had never followed up with the boat. So last week I replaced the impeller. The old one was missing all the fins and looked like it had sucked up a bunch of sand. hooked up the muffs and tried to start. No go. Spins but won't engage flywheel. Installed new starter and it turned over ever so slightly before the starter quickly began to over heat and smoke. I let starter cool and pulled all the plugs and cranked various amounts of water out of the cylinders. Checked oil on dipstick and oil level is good, no water, and oil is still clean/amber (I had changed the oil/filter before last trip) dried, cleaned, and reinstalled plugs. Engine fired up and ran rough for a bit before smoothing out somewhat but still not running smooth at idle and I notice some steam/exhaust coming out the breather tubes. After a bit the steam dissipates and looks like small puffs of exhaust. So I shut her down and next morning did a compression test and these are the readings: cylinder #1-175, #2-180, #3-95, #4-175, #5-175, #6-175. So...looks like cylinder #3 has some damage or perhaps a bad valve? What should I do from here? Any thoughts appreciated!
