454 Mag. getting hot, HELP
1994 454 Merc. mag, carbed. Not used often, so new impeler, new circ. water pump.
On hose, water flow seems a bit low, but water si coming out whre it should, at STD or a bit higher RPM's. Engine gets to about 175-180+-.
Possible restriction in water lines due to age? or thermostat?
I wouldn't think it would get hot just on idle, and didn't take i tout for sea tret yet.
Any ideas? Thx

take inlet hose off sea pump. stick garden hose in and blow out back thru drive or transom pick-up. especially if it is a drive pick up. the fitting in transom where both hoses mount is the skinny spot and stuff can back up there.

If you have a sea strainer take a look at it,,,,,,its always empty on a hose,,,,not enough volume
