    2005 SSi 6.2 MX MPI Brav 3 Impeller(Sea Water Pump)

    Thanks for the tip. Got a case delivered last Wednesday. Also installed a new pair of water shutters and the SB side exhaust boots. Last item to address is the cracked water distribution housing.

    Thanks Wingnut, Excellent explanation ! I have a pair of swing doors on the way. The only part left in place was the metal hinge strip and some toasted end grommets. In terms of the winterizing fluid ( pink stuff ), I see a few of the "marine/RV" products on the shelf that contain propylene glycol and also claim that it contains no alcohol. Therefore, is it safe to say that any of the products that contain pure propylene glycol are OK to use in a marine engine and be non-hardening for pump impellers ? The prestone is available, but at 47, its not practical. I see other bonafide alcohol-free marine engine antifreeze products on the market that are a bit more reasonable at 32, Still somewhat costly. Long story, short...whats everyones thoughts on the pure propylene glycol and its compatibility with our boats' engines internals as well as impellers and seals Thanks ! BC

    Wingnut...you are on it ! Yup, from the schematic of the area I'm working on, it shows these "shutter-flap" or swing doors. Figured, I see these when I took the boots off to replace them. After I took the boots off the port side, I was anxious to see what this swing door assembly looked like, got myself real small so I could get back in that area and, yup....... ......they're gone, non-existent.....Thought maybe the swing doors we're not part of my assembly, but after reading your post wingnut, realize, they should be there. 1. What does this swing door do ? 2. Whats the issue if I operate the boat without these....Haven't taken apart the starboard side boots yet, but I'm sure the SB side is gone too. 3. Is the non-existent swing door jammed up somewhere is the "Y" pipe ? !! is it retrievable ? Hard telling how long these swing doors have been missing. Had the boat for 10 years now, and never has these part disassembled. Thats for all your tips and help ! BC

    Thanks for the Info Wingnut. I was suspicious this cheaper pink stuff may be the culprit

    I think its been at least 3 years. Just got old and brittle. As soon as I pulled the out flow hose from the stock pump, big chunks of impeller spilled put...even got little pieces out when backflushing. Any ideas if the pink winterizing fluid that I flush through the motor before putting her up for the winter is bad for an impeller ? BC

    Just wanted to give an update on this. Just days after this post I received my new sea water pump from Hardin Marine...nice pump !... Bigger Bearing, stainless housing w/ removable and replaceable wear plates. Even takes the stock impeller. Its truly serviceable now ! Had it back together in about 45min-1hr and then took her for a test run. Everything worked as expected. After a few trips, I noticed the the rubber boots coming from the exhaust risers that fit into the hard line, "elbow tube" and in turn fit into another rubber boot..I guess these are referred to as "bellows" . Anyway, these were split and starting to spit water from them. So, I replaced the both boots on the port side; they were both bad and ready to bust at the seams. As it turned out...you guessed it....the starboard side boots were also swollen and spongy. Waiting on those parts now. as well as replacing the cracked port side of 6.2L, the Water Distribution Housing. Bottom of engine assembly on port side I believe all this may be collateral damage from all the heat generated when my sea water pump failed when on the lake this summer. I'll be doing a more frequent replacement of my impellers now that the Hardin Marine Pump is serviceable BC

    Thanks Wingnut. Ordered the pump with the pulley attached. Your info gave me the confidence to push this job across he finish line ! Now , this new pump set-up will be easier to service. Appreciate the tip ! BC

    Ok. Just watched the video on the Hardin link. That answered some of my questions Although, with this stainless setup, I was not aware that I will still be using my stock manifold thrust plate. I suppose the plate you put in between there makes it ok to do...just want to clarify. Also,from the video, the hub on the inside of the impeller is larger due to the larger pulley shaft/bearing. They say it takes a stock Mercruiser impeller, but is the stock impellers center hub area large enough to press a stock one on there ?

    Thanks for taking the time to reply to my post. My 6.2 engine is raw water cooled. Will this Hardin pump work on a 6.2; the link states 350,496,and 502. Its this the correct part number for 6.2 ? So, besides pulling off various cooling hoses within reach and inspecting those for pieces, are there any other areas that are hot spots for pieces of impeller ? As far as the Hardin pump goes, the points regarding the engineering of this pump seem much better than the stock brass pump. Does everything bolt up the same , stock brackets and all, with this stainless version considering the tight confines I'm working withe ? Sounds like the best way to repair with this beefier unit considering the age of mine. Thanks for the details. Appreciate it !! BC

    Whats an effective way to do this ? This is a great tip. Is there are way to make some connections with a hose or something where flushing would cause loose pieces to exit from ?

    I finally got the chance today to remove the sea water pump in a effort to determine why i overheated last time out. I had to remove (4) 10mm bolts that held the Gen3 cool fuel filter to a bracket plus all that Wingnut suggested to get the pump out. Once the cool fuel filter was pulled aside(no disconnections were made to the filter's hoses and gas lines..just moved it aside) After that I had a clear shot to the two stern inlet and outlet hoses as well as the entire pump assembly. The moment I took off the pump's outlet hose, bits of impeller spilled out. I then figured the impeller was shot. Once at the bench, I disassembled the 2 haves of the pump and found a destroyed impleller. As Wingnut thought, the pump is Brass. My question is....on the stern side half of the pump(the end that has the hose connections on it) it has a mildly deep groove in the brass where the impeller rides. Should this half of the pump be replaced ? The bow half of the pump were the pulley shaft is and where the impeller itself drops into, doesn't show much grooves. The end play on the pulley/shaft assembly is tight....no wiggle/slop coming from the bearing assembly. I'll leave that alone.... Just need to know what parts are available to address this stern half of the pump which is mildly grooved. Thought I saw some sort of plate set-up that drops in the impeller cavity area and another that lays on the stern part of the pump that I have the grooves in Please advise. Thanks for your help ! BC

    Thanks Wingnut ! Excellent tips. I don't think my sea water pump assembly has the 2 little air actuator hoses(auto drain system components). Not sure what where the high vent hose is ? My boat is on the trailer out of the water....does the high vent hose pertain if the boat is in the water ? With all that in mind, I thought my pump was all plastic.. do the auto drain system set-ups only have the cast bronze pump.?....it'll help once I get the pump out and take it apart and see what i got. Your advise is well taken. I'll have to check the shaft/bearing for "play" and get all the necessary parts to make it right. All the above mentioned thoughts are much appreciated. BC

    Thanks everyone ! impeller failed while underway this weekend and luckily got her back on the trailer to do the work. I appreciate the help ! BC
  14. Hello All, Can anyone direct me to a good thread as to how to remove the sea water pump housing and impeller from my 6.2L MX MPI w/ Bravo 3. I know its mounted on the front of the engine, but looking at the job the cool fuel filter is in the way...big time ! On the 6.2L model, what needs to come off in order to get good access to this impeller/pump ? Any help or guidance would be greatly appreciated BC
  15. Got an issue with my speedometer gauge that I need some advise on. After having an awesome time at Bull Shoals lake last week with the family, we meet some friends at Lake Ozark and boated there. Uncovered the boat and right away noticed the speed gauge was missing, looked under neath and found it there swinging by the speedo cable. Looked simple enough to remount, but noticed the plastic white "housing" around the flat gauge itself seemed to be cracked/broken off the black outer sleeve/ring. This black outer sleeve/ring seems to fit around the white casing of the speedo plate and has small set screws that snug it up once mounted in the dash hole where the speedo is located in the instrument cluster pod. Doesn't seems to be fixable…or maybe it is. ANY IDEAS ? Or should I get a new one from Cecil Marine ? http://www.cecilmarineonline.com/4-inch-65-mph-speedometer/?page_context=category&faceted_search=0 Saw the exact one like mine on-line. Diameter of mine measures a little shy of 4", so I guess the 4" one they sell is the correct part for me. Does the speedo cable detach from the back of the speedo gauge or does the new gauge come with a new cable back to the motor ? Thanks, BC
