Twin 350 Magnum MPI Horizon MerCruiser w/ V-Drives
Re: 2005 Sea Ray 290 Amberjack - great boat and ready to cruise & fish
Yes the risers were replaced in 2015, manifolds were still in good shape. It's a Closed Cooling system and I would flush them after each outing either with freshwater or Salt-away. Mercruiser has added a quick connect to the raw water systems which makes it easy to do after each trip. I also have all the maintenance & repair receipts/records that I have done on this boat. The boat has been kept at my pier on a lift.
Let me know if you have any other questions. Thanks for looking.

Yes the Cool Fuel Module is cooled with raw water thru 2 fittings,...in/out. Get a good close look at where the water is leaking from. Not unusual if you have the old style O ring fittings, new style...
And I don't think it is as simple as buying a plug. There is blue hard plastic/something on the inside which would prevent me from inserting a plug, without the need to somehow clean the hard plastic...
