Crusader 454 getting hot - help please

Re: Crusader 454 getting hot - help please

I have a 1987 454 Crusader raw water cooled, running in brackish water for the last 4 years with light use. My starboard manifolds are running hot, low water flow out of the mufflers. raw water pump has been pulled and ckecked, intake flow through both engines the same to thermostat housing. flow to the manifolds (RWC) is low which i'm sure is causing the problem. Flow is good throgh the oil cooler, I have pulled the circulatig pump and it looks fine however I will replace it since it is off. I have used a garden hose to run water throgh the circulating pump ports and the manifold ports, flow seems equal and good.
The problem seems to be flow from the thermostat hosing to the manifolds. both manifols have been pulled ckecked and cleaned. The risers are new from Crusader.
Today I will be intalling the circulatig pump and reassemble the rest and trying it initially without the thermostat and crossing my fingers however I don't believe it will help.
Any suggestions would be appreciated.
