    Yes, that’s the boat, and there’s no scoring. Here is something I think I missed too.

I have replaced the impeller, the water pump, the sensor units, and the thermostat, and replaced the original wet joint manifold/spacer/and riser with a brand new Dry Joint Manifold manifold/spacer/and riser.

    Manifold install help

    I ordered Dry Joint Manifolds from Hardin Marine for my Mercruiser 5.0L Efi engine. First, this manifold requires the 3" spacer between it and the 7-degree riser. The bolts that were sent by the manufacturer with about 1" too long. So they didn't secure all three pieces together. So I found some...

    Corrosion in Closed Cooling system

    I bought a 1999 Sea Ray Express Cruise with the Mercruiser 5.0 EFI. It has a closed cooling system. I have been working on it for a while and changed the zincs, impeller, oil, and water separator filter. Topped off the radiator fluid. I hooked the water hose up to the stern drive seems to be...
