Got the new muffs with heavy metal spring and dual inlet for hose. Hooked it up after verifying the pump does pump water in a 5 gallon bucket back into the bucket. Fired up the boat with the garden hose on and i am still not seeing any water movement...So then I tilted the outdrive all the way up and tried it again (normally I don't like starting the engine with the outdrive up but wanted to see if it helped any and low and behold the raw water pump primed and was pumping like crazy almost immediately after I squeezed on the muffs to keep water from shooting out the sides but once it was primed I didnt have to hold them. When I tilted the out drive down and tried it again I noticed it was drawing air into the pump (could see with clear tubing on it). I checked round the outdrive saw slow drip develop from where the hose connects to the fitting that goes through the gear case. I am now thinking either the plastic fitting is cracked or the o-ring I put on it to seal to the case was too small which allows for ir to get drawn in there which my also be why the system is hard to prime.
