GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
Impeller housing is new. Thermostat is new. Would a chemical flush like barnacle buster make a difference? I’ve flushed all heat exchangers with water, looking for impeller peices and they appear OK. I have a closed system.
I seem to have more water coming from the Starboard engine than the port and the pet engine is running slightly over 180 degrees. Starboard runs just over 140. Risers are inspected and in good shape.
Question: could this be caused by impeller installation with fins in wrong direction?
My Impellers are working however, my port side temperature gauge is not working. It is a new Gauge. I replace the sensor on thermostat housing and temp gauge never went above 100. I replace the thermostat because it seemed like it was stuck open. I still have a slight amount of steam from the...
Fuel pump is not attached yet. I only meant, is the lack of oil enough to keep it from turning. The washer is on the shaft where the cam is. Not under a nut. I can try a pic tomorrow, but, I can turn my current assemblies, even the one that is worn out, but the new Amazon one seems locked up.
I just received the Amazon pump and it looks nice. However, I am unable to turn the pulley. There is no Oil and the impeller assembly is already bolted on. Also, there is a loose washer on the water pump side of the shaft. Is this normal?
Thanks for the great advice!
I pulled these assemblies and installed the new impeller kits. One of my housings was nearly empty of oil, the bearings feel rough and the fuel pump arm is worn. Also, it appears the shaft is bent as the pulley wobbles...
Should I pay the premium for the...
Great video. I wish my engine was on a stand like that!
I am probably going to remove the raw water / fuel pump assembly from the motors for this replacement. I’ve ran out of options and patience to do it while attached to the engines.
I almost remove the whole assembly but, was concerned about fuel spillage from the lines. Just close the valves and catch what runs out of the lines? What service should I perform on fuel pumps? Apologies, I don’t have a service manual for these
Engines, yet. Source for service manuals?
Thanks!
I purchased a neglected 92 Wellcraft with twin 7.4K Inboards and closed cooling system. Port engine overheated, so, I bought impeller kits and started the replacement project. The raw water pump is part of the fuel pump assembly. The port engine’s assembly slid right on, then I spent 3 hours...
