I have a 1983 Volvo penta AQ125A. The other day I noticed my exhaust smoking in engine compartment and realized my impeller wasn't working. So I pulled it out and the bearing had became dislodged from the rubber. So I ordered a new one, installed it tonight and now I have no water in the system. I pulled the impeller housing off engine and turned motor to see if the shaft were the fork goes is turning and it is. Reinstalled and it isn't pulling from the tub of water the out drive is in. I lightly sanded the impeller housing to get all the old impeller and water residue off. When I pulled off the old one there was water in there but may have been old. This boat is new to me of about 3 weeks. Wondering where to start? Thanks for advice!
