I posted this in the wake garage as well some of you might have read it this am . Kinda long winded
Hey guys I pulled my boat out of hibernation yesterday and cleaned it all up . After it was clean I decided to hook the plunger up and warm up the oil for an oil change. I turned on the water hose and fired up the boat and watched carefully for water to start flowing out of the exhaust . NO WATER !! I noticed the engine starting to over heat and shut it all down. My first thought was the new aftermarket impeller I put in last summer was no good . So I pull it apart and it looks good and I start thinking its a issue with the plunger fake a lake set up so I went and got a new fake a lake a new thermostat and for good measure an impeller kit to keep in the boat . ( always better safe then sorry right) I replaced the thermostat thinking it might be slamming shut from the cold hose water or just stuck shut from being original so with last years impeller still in the pump . ( trying to be a cheap ass and get more hours out of the fairly new impeller) I hooked it all up again and still no water flow . At this point I'm thinking restriction or blockage some where . I do run the delta and would not be surprised if there was seaweed or some crap causing blockage . Remember at this time I did not replace the impeller yet only the T-stat but figured even if the impeller is bad the fake a lake should still flow/push water through the engine . Well it would not flow through . At this time I'm pulling hoses and flushing water back from the impeller pump to the pick up to make sure there was no blockage in the water intake . No blockage . Then I'm a little bewildered and impeller pump comes back off and decide its time to look at the oil cooler which is first in line after the impeller pump for blockage . Well F**k me there was half of an old impeller stuck in there .( not from when I've owned the boat mind you ) I dig it all out and put everything back together and turn on the hose fire it up and still no flow . Now I'm thinking maybe I should have installed the new impeller thinking its just lost its suction ability . At this time I pulled the hose off the Vdrive coming from the through hull water intake on the bottom of the boat and turned on the fake a lake and its struggling to even push water up the hose to the Vdrive. Now for a fake a lake to work does it rely on suction from the impeller pump to help pull water up into the engine ? After I determined the fake a lake wasn't pushing enough water into the engine I shove the garden hose into the fitting at the Vdrive which fit pretty snug and was kinda cool . I tuned on the water fired up the engine and now its flowing well the engines running and not getting hot with the hose hooked up that way . I think I'm going to replace the impeller and dunk it in the water and fire it up and see what happens figuring the force from sitting in the water will supply positive water flow to the impeller and eliminate the fake lake being fart of the problem. So my questions are...
1. Should I just replace the impeller for good measure ?
2. Does the fake a lake rely on impeller suction to help pull water into engine ?
3. Do you gurus think the impeller running almost dry on the first start up ruined the suction ability of the new impeller even if its still all in one piece ?
4. Could it be just not sucking well from being in the boat all winter and the petals being folded over?
5. Should I rig up a system that allows me to hook the garden hose directly at the Vdrive instead of the stupid fake a lake ?
