I have a 1971 tower of power 1350 and am wanting to find out if the cylinder bleed hoses are routed in to the correct location and that the check valves are in the right spots. 3037534 is serial number. I will try and describe what I have going on now the best I can.
There is one line running from the upper main bearing to the port between cylinders 2 & 3 with only a check valve in the port between 2 & 3.
There is one line running from the port between cylinders 4 & 5 running to the balance tube/reed block fitting on cylinder 5 & 6. With only a check valve at the port Between cylinders 4 & 5.
There is one more hose running from the lower main bearing port to the balance tube/reed block fitting on cylinder 3 &4. With no check valve at all.
There is also hoses also running between the balance tube/reed block fittings as well.
Let me know if this sound right I have looked at the parts brake down for this motor on the various mercury parts stores and suspect the lower two hoses are crossed because the lengths they give for the lower two hoses are to short for the way it is routed now and it appears that there should be a check valve in the lower bearing cap port.
Also if it needs to have a check valve at the lower main cap port what will it hurt if it is not there? And Where Can I find a New one, They are no Longer available from mercury.
Thanks for any help.
