The last few trips to the lake I have been noticing more water in the bottom of the boat than normal. Yesterday I noticed there was a little bit of steam that would come out of the exhaust under acceleration but temp gauge didn't read much hotter than normal and was normal when cruising.
So I started thinking impeller so today I take the cover off but the impeller looks just fine, all fins intact. I also checked the hoses for obstruction but found none.
So I hook up the fake-a-lake and notice that the water leak is coming from the raw water pump and that the boat is not sucking up as much water from the fake-a-lake and very little water is coming out of the exhaust.
So is my water pump dead or is there something else I need to try?
It could just be the seal. Mine was leaking when I bought my boat. The seal cost less than a buck and was pretty easy to replace. Pump removal was required.
It wouldn't vacuum air into the line, just not getting all the water into the engine. The circulating pump at the front of the engine doesn't "pull" it just circulates whats in the system. The seal would not obstruct water getting to the engine, just makes it leak if its not seated down all the way or its missing for some reason. The seal comes with a new impeller.
Took the water pump off today and took it apart. We ordered a new one from skidim that will be here Monday.
The impeller is still just like new. The bearings and seals inside the pump totally grenaded. There were 3 ball bearings inside the bilge and a piece of metal that holds them was near my side compartment, I saw these yesterday but had no idea where they had come from until now.
I also had two pieces of impeller in the trans cooler screen that must have been from a prior impeller.
I also got the thermostat housing off to see that the thermostat was corroded and almost stuck shut so I will be replacing that as well.
Hopefully after getting all of this done I won't see any more problems, I guess if there are then it would have to be the recirculation pump.
Another question, the boat had a heater in it that I removed and just installed a U hose to connect the hoses that ran to the heater. This was 2 years ago I did this but is there any chance that some of my problems i am having now could be because of these hoses running to and from the front of the boat.
while your at it call skidim back and order all new hoses for the boat.. my j hose split on me on the first trip out this year and almost flooded the entire engine compartment... I checked all of them when I winterized it after I bought it and they looked fine.. but looks can be deceiveing.... LOL
