I keep my 270 on a lift in a highly silted saltwater channel. A couple of weeks ago I got stuck in sticky silt. Engine got hot (200f). Shoot me, I've opened a can of worms. After removing damn near everything on the front of the motor, I pulled the seawater pump. Getting the hoses off of it was a real treat. I found the impeller intact but the center brass core was split so it didn't rotate. Replaced it, inspected the heat exchanger, put everything back together, replaced all the fluids, and fired her up. Started fine but the temp was quickly getting scarey. I pulled the hoses off of the seawater side of the heat exchanger and had no water flow... bone dry.
My current guess is the oil cooler is clogged.
I swear Sea Ray had no business sticking a 496 in such a small hole. I've got to pull the manifold and riser while laying on the engine just to see what's going on.
Am I right?
