Sabre water pump
I have a 28''Sabre with a Atomic 4 engin. I need to replace the water pump impeller which is located in the lower left back corner of the motor. Can not figure out a way to get to it without pulling the motor. Does anyone have any suggestions?

Sabre water pump
Remove the grease cup body using a 7/16" wrench.
Remove the four screws on the cover plate and the cover plate.
Grab the base of the impeller, not the vanes, with a needle nose plier, etc. Wiggle the impeller until it moves out of the housing (many times it can be wiggled out without removing the grease cup). The impeller is held to the shaft with a small bronze circlip.
Thats it.
Hope this helps.

try asking on the sabre-list e-mail group. You should get some good advice there. (just go to "join e-mail lists".

Sorry to bring up an old thread, but I have a Sabre 28 with an Atomic in it and I replaced the impeller this spring. Started the engine yesterday and at a low rpm, there was no water going thru the engine, causing the temp gauge to rise. If I gave it a little gas, the pump would sart to draw water and cool the engine down. Back off on the gas and the water stopped.

Thoughts, comments........

On my A4 the orginal pump was so worn out i had to buy the Moyer Marine unit and replace it

You would need to inspect the pump and look at the shaft bore (my bore had worn huge) and the wear plate the impeller runs on to make suction

Also if the cover plate and rear of the pump wear the sides of the impeller rub is worn it will not work well
