1997 43.L Chevy 350 6 cylinder. Freshwater. Manifolds and risers are
original.

Tuned up just weeks ago with only 4.2 hours on the engine following the
tune-up.

Thermostat was replaced in spring.


I wonder if your tune-up guys pooched something and didn't tell you.
Not likely. More likely a scenario like this: Plastic bag gets sucked up
against water intake. Water is restricted or cut off completely. Engine
overheats and water pump fries. Engine shuts down or is shut down and
plastic bag slips away. After inspecting the water pump, mechanic
suggests that the owner ran the engine without water. Owner suggests to
mechanic that he should have seen that the water pump was on it's last
legs when he inspected it. (Write your own ending to this story)

Well, I keep reading about "impeller failure," but I dunno about that. Jim
boats on a freshwater lake. Bags, yes, but sand, sandbars, and the usual
crud one finds in coastal waters? Probably not.


We often take the boat off a beach and often kick up sand when moving over a
sand bar.

These folks taking care of my boat are pretty reputable. I am prepared
for, although I think it is unlikely, for the worst case scenario of an
engine rebuild and new risers, possibly being without the boat for a few
weeks.
