Help! bf 130 water pump problem

[jdman]

The impeller disintegrated. I replaced it and now I am not getting any water from the tell-tell. Does anyone know what would cause this? The manual says to put some grease on the inside of the impeller lining. Didn't specify what type. I had high temp wheel bearing grease on hand so I used that. Does this sound right? Never used grease on impellers before. Also, my plugs have alot of black on them, and it is idling rough. Could this be caused by the overheat? I didn't know the pump was bad until the overheat cutoff killed the engine. It would start back up and run for 20 seconds then cut back off. There was no warning buzzer and the engine light did not come on. Does anyone know why? Thanks in advance. Nick

wow bummer<br /> well are you sure you got the water tube lined up with the pump? are you sure the impeller drive key did not fall out while you were installing it?maybe parts of the old impeller are blocking the tube. and I hate to say it but there is no overheat shut off. it got so hot the pistons stuck to the cylinders maybe. now its time to do a leak down test or at least a compression test before going anyfurther.and then test your alarm sensors and circuits for proper operation. and next time shorten up the maintence cycle on the water pump.<br />good luck and keep posting

Thanks for the reply rodbolt. The way this thing is made, the tube is stationary, so it has to line up correctly to go together. Disintegrated is really a bit of an exaggeration. It was in about 4 or 5 pieces, all of which fit back together, so I'm pretty sure there is nothing blocking the tube. The key was in correctly also. As far as the shut off, I don't really know if it has one or not, but it didn't really seem to be seizing from heat. It just cut off while running and immediately started right back up. It would run for twenty seconds (timed it with a watch) and then cut off, same as if cutting off with switch. It is running fine now, although a little rough at idle (barely noticeable), which I figure is because the plugs seem to have some carbon on them. I really don't think the engine was damaged from excessive heat. I've only owned this engine since May, guess I should have changed the impeller first thing anyway. Thanks again for the reply, and any more opions are greatly welcomed. Thanks, Nick

Re: Help! bf 130 water pump problem

What is the year of the motor? If it is new the impeller should not have gone bad unless you have run the motor with no water supply. Do you have a Honda control there should be a warning light and buzzer on the control or one in the dash of the boat, do they work ok? When you ran the motor did you have water flowing out of the prop center if so that would be one sign that the cooling system is working. Try to pull the tell tail hose off of the cowling and see if there is a piece of impeller that is blocking the outlet, it happened to me this summer with my small rude after the rebuild I had no tell tail but the fitting on the block for the tell tail hose was leaking after removeing the fitting there was a small piece of impeller blocking the passage.

Rad is correct .With this engine , in an overheat situation , you should get a horn and light . then a powerloss ,then stall .All of that is relayed and controlled by the ECM which monitors all the signals all over this thing then sends out it"s own thing to make it all work together.You will need to monitor engine temp to decide if that is causing the failure.Do you have a breif BEEP BEEP when you first turn on the key and do you have the engine check lights?

It does have two lights on the panel, one oil light and one engine light. I don't know if they work or not, I haven't had a chance to check them manually. Also, this is the first problem I've had from this motor, so haven't been a reason for them to come on till now. When I ran it on muffs, there was some water coming out of the prop, and I did pull the tell tell hose loose from the fitting. Nothing came out. Hondon, the powerloss and stall that you describe sounds exactly like what it did. But I heard no warning horn. And there is no beep beep when I first turn the key on. Should I hear this? Thanks alot for all the help guys. Nick

Re: Help! bf 130 water pump problem

Ok here's an update. I pulled it back apart and found that the rubber grommet in the top of the impeller housing got pinched by the tube when I put it back together. It was not pinched enough to completely block the tube, but it did cut a piece out of the edge. Seems like this would cause a considerable loss of pressure though. I'm keeping my fingers crossed that this is what it is. Any suggestions on how to prevent this from happening to the new one when I put it back together again? I did put grease on the this one. Thanks again guys. Nick

Re: Help! bf 130 water pump problem

The green oil light should be on when ever the motor is running, it shows that you have good oil pressure. If the green light is not on and the motor is running it is a good sign that your check lights are not working and you need to find out why. As for when you put it back together take your time and have a extra set of hands and eyes to watch with a shop light and make sure that it lines up right.

Re: Help! bf 130 water pump problem

Can someone tell me if there is supposed to be some kind of seal on the water pump housing where the driveshaft goes through? It is a '99 bf130. I don't recall there being one there when I pulled it apart, but now I'm wondering if maybe I lost it and didn't notice. My manual is not very detailed on this. Thanks, Nick
