I have a 2000 Sea Ray 260 Sundancer with a 5.7L EFI 350 CID Mercruiser (GM) Bravo 3, LH rotation. Raw water cooled, Serial number is 0L653896.
My Mercrusier started overhearing at idle last weekend, and I assumed the seawater pump impeller was the culprit. I removed the seawater pump and replaced the impeller inside, reassembled and mounted back on the engine. After all connections were made, I removed one of the plastic drain plugs to ensure I had a water flow. Then, i started the engine and it ran fine. I removed one of the plugs again while running at idle, and had lots of water pressure at the plug. I then turned the engine off to replace the drain plug. After a few minutes of putting tools away, I attempted to start the engine again. This time, I got a "clunk" from the starter and the engine did not turn. The second time I hit the key, all I heard was the high-speed spin. Having had a starter issue before, I assumed a bad starter solenoid as a coincidence. This morning I removed the starter to have rebuilt, and was surprised to find all the teeth broken off the bendix inside the starter. I felt the flywheel with my fingers, and it seems to be unharmed.
It appears that something is causing the engine to lock up, so much that the starter could not turn it, and sheared off at the teeth. Any ideas? I would assume that i did something incorrect with the water pump reassembly, but it ran fine for 5 minutes prior to this. I'll still need the starter rebuilt, but there seems to be something else that needs to be done.
Any help would be greatly appreciated.
THanks!
