Here's something I am trying to get my head wrapped around. I have twin 200's. One has a newer powerhead - both are running well 'at the moment'. Both are running water through their systems when on and keeping things nice and cool. Both pee holes flowing nicely.
The older of the two will not allow for a freshwater flush - not a drop ( motor off, freshwater connected to the freshwater flush house on the port side of the motor). I have removed the lower cowling to gain access to where the flush house connects to the an elbow that goes into the engine - the house and elbow are not clogged. I have tried numerous flushes and wire contraptions to try to get. 1/2" into the block - I literally hit a wall.
What could cause this ? I'm assuming it's caked with dry, hardened salt ? But this is having no affect on the engines overall cooling capabilities - just the ability to fresh water purge the block.
Any ideas what is going on and how I can alleviate it ?
Thx.
