Cooling problem even Merc techs can't answer.
Engine temp at 200-210 F, exh manifolds port, 140-160 F, Stbd over 200 F.
Unit has new intake water pump and engine circ pump. Standard sea-water cooling.
Manifolds boiled out with acid, rodded, flushed. Equal water flow thru both on water flow test.
Exh elbows new, new thermostat, sender and guage, new engine circ pump.
No broken hosesand It appears it is determined to defy all laws of thermodynamics.

Why didn't I just satisfy my fishing urges from the bank ?????????

Any suggestions, other than put to sea, set fire and call Coast Guard ??

I could be totally wron on this, but I believe the 898 is a small block
chevy 305 CI Engine.

Now this is a wild shot but if this is a new or a fresh reman enging,
it's possible tht somebody could have put one of the intake manifold
gaskets on backwards.

(Yes..it can be done)

What happens is that there are coolant ports that flow water fromt he
head to the intake manifold for circulation,a nd it's quite possible
that if a gasket is backwards, a channel could be blocked off, thus
halting the circulation. The only way to find out is to pull the
intake manifold and inspect the gaskets.

Another is check the engine timing. if it isn't up to spec or is
running retarded advance, it will make the engine run hot due to the
spark is firing the fuel too late.

other thant hat... I really don't know.

Good Luck!

Or running too lean for a variety of reasons....clogged carbs, clogged
injection, manifold gasket leaking, cracked intake manifold, loose vacuum
hoses.....

Wanna bet he left gas in the carbs during storage?
