- Mercruiser 5.7efi w/ Bravo 3
2001 SeaRay 240 Sundeck
5.7 mercruiser with Bravor 3
650 hrs
Previous owner neglected this boat and I'm pretty sure it sank on land given all the random things I've had to replace.
Now that I've got it running it's making a squeak and knocking/pinging sound. The knock came first and then after running it a bit more the squeak started. Sound seems to be coming from the back of the engine and possibly the port side. I can feel the knock anywhere in the engine and it increases with RPMs. The Bravo3 shifts smoothly fwd and reverse. The sound is while in gear or out.
I have looked in each cylinder and not found anything unexpected, I have pulled the port valve cover and everything looks good while running. It really doesnt sound like an exhaust leak. I'm thinking something on the back end but haven't pulled the drive yet. Hoping somebody can see in these videos below something familiar so I can go right to fixing instead of wasting more time diagnosing.
