Hello to anyone that can help, I'm a first time boat owner, I bought a 1988 bayliner cuddy capri, with a 1988 omc 5.0 cobra sterndrive motor in it, I drove it before I bought it and it drove very well. I reupholstered the seats because of weather damage and had it looking new. While running the motor one day in the yard with the hose connected to the outdrive for about 25 minutes, I shifted it in gear to test and it shifted fine, I turned off the boat to clean up from doing more cosmetic work, I decided to start it one more time before I went in for the night and it just made a clicking noise, but it wouldn't crank. I've changed the starter and the assist solenoid and it still just makes a clicking noise, a friend turned the engine from the front to see if the engine was seized and it turned. Everything else works, it's a GM motor. Can anyone help, and what are my options, if the engine is dead, what would it cost to replace, rebuild, repair???? Thanks in advance.
