1984 Force 85hp Outboard NO WATER FLOW

[imte1]

Hello to everyone! I am new to the site. I am also a new boat owner. I purchased a project boat that I just could not refuse lol..It is a 16 1/2 footer all fiberglass with trailer and 1984 Force 85hp outboard for $400...When I purchased the boat the motor would turn over but not fire. I have fixed that problem and now have the motor running (stator was bad). After getting the motor to run I noticed no water was exiting the holes in the rear of the outboard. I turned the motor off and allowed to cool completely while I wondered what the problem could be. I started the motor up again and still no water was flowing. I removed the thermostat which had corrosion all over it and some corrosion was visible in the power head. I replaced the thermostat and gasket. Also since I noticed no water was at the thermostat I removed the lower portion of the outboard to replace the water pump assembly. I noticed that the impeller appeared to look just as good as the new one I was replacing it with. This concerned me so I inspected the water tube going up to the power head. I used a long very thin wire brush and slowly ran up the tube and removed with no dirt or corrosion on the brush. I then used compressed air and blew into the tube and did have a slight bit of air at the power head where the thermostat was removed from but not enough air like I should have or think I should have. I went ahead and put the new water pump assembly and new impeller on and reassembled. I still have no water flow. I have tested with a water hose using the "mickey mouse ears" and also tested with a large plastic bin with lower leg submerged both with no success. What else could be my problem and what steps should I take next? I did purchase the manual for the motor and that was worth it to help with the stator, trigger, coil, etc testing that allowed me to get the motor running. I am new to boats and boat motors but have worked on cars, trucks and motorcycles for some time now.

Thank you in advance for your time and assistance.

Josh

The 2 holes in the back of the leg are just relief holes. You should be seeing a light spray of water, but not a solid stream. It sound like you checked or replaced everything you could.
I always have more luck with the bucket method vs the muffs.
See this link to add a telltale.

If the boat has been sitting for awhile not being run, it probably needs a new waterpump impeller. It's also a good idea to add a tell-tale to your cooling system so that you can see at a glance if you are pumping water. There is a link on this site with instuctions for both the impeller changeout, and adding the tell-tale.

wierd, almost sounds like the drive shaft isn't spinning. first, i would not try using muffs again. i tried that w/ my 85 & nothing. something about back pressure that some of the experts here know about. i test right at the dock but a submerged LU will work. as earlier posted, you should get a spray from the two exhaust ports in the mid leg at low rpm. it's possible the housing is scored or the gasgit underneath is shot & all the water isn't going up the tube. hopefully frank a, roscoe, jerry or ritt will chime in. any of these guys will know.
