Hi there,
On our recently acquired 2700, the engine surveyor report indicated the risers need to be removed and re-gasketed (if not replaced) and the trans coolers were showing some concerning corrosion and should be replaced.
On the risers, indicated part # is 807988A03. I assume on these parts we should stay Mercruiser OEM or is aftermarket OK?
Since they are freshwater cooled, do you have to drain the whole cooling system or is it possible to just catch what spills out? I assume it is pretty straightforward, but any tips or tricks regarding how to do i is appreciated.
Thank you!
