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

    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 ?

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

    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 ?

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

    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
  8. 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
  9. 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

    Ha. You do !! Kudos to your Dad. Let him know thanks for all his hard work; it paved the way for the cool stuff Ford now develops. Wouldn't own anything else.

    Large SUV

    Been towing our 236 SSi with our Ford Expedition. Can't go wrong with a Ford. Have 4 of them… 2 mustangs, SHO taurus(twin turbo), and Expedition(on my second Exped)…yup..I got a car problem...Ford Engine technology is far superior to GM. From the overhead cam design, to the multivalve head design, etc, etc that Ford Engineers have been designing for since that late 99 to very early 2000. This engine design offers superior throttle response, valve timing, and excellent pull out of the hole performance, all while obtaining much better gas milage that a typical GM pushrod motor…Oh, by the way...Did I mention styling….. Get the Ford, you won't be disappointed. BC
  13. Heard from many mechanics. If your motor used synthetic from birth to present…keep using it. Although, if you have a seasoned motor that has been using conventional oils for many hours/miles do not change. I have always used the mercruiser recommended oils in all my boat motors and never had a oil related failure or improper oil control. BC

    Engine Backfires and Loses Power Coming Out of Hole

    Yup. I agree. Fuel inj motors don't really "backfire". When you start the motors, check the port side motor fuel pressure at the schrader vale area on the fuel rail. Fuel pressure gauge is inexpensive and can yield a lot of info in terms of fuel. Then check the voltage at the Mass AIr Meter. A bad MAM/mass airflow sensor whichever term you prefer, may cause a too rich or too lean condition, erratic idle(as you've seen displayed on your tach), and poor performance. May be source of the howl you hear. Throttle Bodies can go bad as well, especially the Throttle position sensor(TPS) part of the Body. Some Throttle Bodies TPS sensors are replaceable, rather than replacing the entire Thrott Bod. These parts going bad will create the inconsistant idle, stalling under load, and perhaps problems after the port motor is run and hot and then shut down and then restarted soon after. Chaparral Tachs are notorious for having a high failure rate. Replaced mine on my 236SSi for the spiking problem as well. This was done per recommendation of the Chap dealer. Although my tach issue never affected motor performance. Mechanically sound tachs that exhibit a spiking response offer a real time display of what your idle or cruising RPM may actually be doing Just my 2 cents BC
