Yet another reason to change your water pump!!!
Well, one of the first things I bought for the boat was a raw water pump assembly. I don't know the history on a new purchase, so better safe than sorry.
Well today I finally got around to changing the impeller and housing. I would say it was a good call. Would you guys recommend flushing the system somehow before I install the new impeller and housing? Thanks and enjoy!! Change your water pumps!! http://img178.imageshack.us/img178/979/10061733.jpg http://img259.imageshack.us/img259/9881/25115246.jpg http://img525.imageshack.us/img525/5742/20189247.jpg http://img206.imageshack.us/img206/1260/37383367.jpg |
YES ,,, BUT BACKFLUSH IT ,Start at the exhaust and do it as much as u can .
DO NOT RUN IT !!!!!!!!!!!!!!!!!!!!!!! It will clog up the block and u never find where !!!!:eek: |
DAAAAAAAUUUUUUUUUUUUMMMMMMMMMMM:eek:

Just flushed the system, doesnt seem to be any blockages. I took the hose that goes to the riser from the thermostat housing, and put the garden hose in there and clamped it on, and just let it backflow. After it flowed for about 1 min, I blocked the line going to the other riser from the housing so I could have full water flow through the system. I did this using both riser hoses, and it is flowing very nice, and clean.
Anything else I should do before installing the pump? |
Might sound a little off the wall but when Mine blew out last year I also used a shop vac which sucked all the loose pieces out. The water back flush should do the trick, but if its still apart it cant hurt

That pump was run with no water.

May have been, I dont know. This boat has been out of the water for 7 years too so that cannot help things.
When I saw it run, it had water running to it and out of it.. How it worked I do not know, but I am 100% for sure remember it exiting the exhaust.... Scary scary, hopefully the headgaskets are ok. The motor fires right up, and has great compression in all 8... Well time for the new pump, and I would say this one looks a little better.... http://img14.imageshack.us/img14/2917/66520668.jpg http://img11.imageshack.us/img11/9337/78589195.jpg |
yes it looks a little closer to normal. But if you have it this far you should go ahead and change it as well. new impellor kit $20-$30 blown engine big bucks.

Oh yeah... Im glad I didn't decide to run the engine this way... :)
