I'm back to tell everyone who may have bee watching, that changing the power pack has cleared up the problem of this engine after ten minutes of running to loose its the left bank spark. The engine was run for 30 minutes with no problem than stopped and than run for another 30 minutes so we are...

My cousin has a 6 cylinder Johnny that after 10 minutes he describes the motor seems to begin running on half the cylinders. He has taken a compression test and all cylinders are the same. He does not notice any warning horns or other clues. The boat has a built in fuel tank. Have we heard of...
Could someone help Identify all the hose's that go to this part. I am inheriting a replacement of the pump and I do not want to make a mistake. The old pump has been removed and I can't be sure of the reconnection of the hoses. Any advice for initial start up after installation,,, Thanks

Noticed that the new water pump kit has an O ring that should go some where in the impeller housing either above the impeller b/t the top (housing) and the impeller or beneath the impeller sealing the impeller bottom and the water pump plate? Which is correct? Also I notice that the new impeller...
