- twin 5.0s w b3
I searched and searched and googled and looked some more -- but I need some help.
I have done ALMOST everything I can do while shes in the water...
Starboard engine is overheating.
Thought it was due to seaweed... its not.
Specs:
2002 Amberjack
Merc 5.0s - Raw Water cooled
Bravo 3
New mercruiser manifolds, risers and elbows replaced 6/16
port motor runs consistently at 170
starboard motor started running hot(er) - never got any alarms or never shut down.
at idle - runs normal - on plane - overheats within 20-30 seconds
changed the raw water pump on Sunday - the vanes were fine and looked brand new... replaced anyway.
replaced thermostat to a mercruiser 160 - same thing.
removed the hose going to the risers and very little water going into risers.
checked the port motor - A LOT of flow into risers.
removed the hose from the distribution hose on bottom right of engine - excellent flow.
I purchased a new circulating pump yesterday, and will be installing it this weekend.
I dont THINK its a riser or pickup problem, since the flow is GOOD up to the risers.
#20 is NOT clogged... i blew air and water thru..
what else am I missing ?
