Re: 5.7 Bravo III SeaWater Pump

Ouch !!!! lol !!!

I guess I'm going to have to become a contortionist and take the thing out myself.

The book value on this 1996 Proline 231 is somewhere just north of 13,000 at the low end of NADA value.

My brother the power of attorney over mother's estate, wants to let it go for $2000, he's nutz. I realize he's just frustrated with having to repair a boat that none of us ever used, he just wants it gone.

I don't think his rationale for not fixing the boat holds water, and it will be really difficult to sell a boat that cannot be demonstrated. How would the buyer know that the engine was'nt overheated and damaged by the seawater pump failure.

I'm actually responsible for the pump failure, I was running the boat in the driveway, and was checking the stearing while running, a few minutes later I climbed out of the boat and the flush clamp and water hose had fallen off, thus the pump didn't have a water supply for a few minutes, I quickly cut the engine. It was the next time the boat was started 3 days later I noticed the temp gauge and then no water passing thru the engine and out the rear of the boat.

I know for a fact that dad never had the seawater pump serviced or changed since he bought the boat in 2001, so the pump could very well have been on it's way to failure before this incident.

There not all that bad (I would rate it at a 2-3). I just changed out mine on my 7.4...not to mention if your pump is anything like mine, you can rebuild them with new seals and impeller for around $40 - $50.

Here is a link to a good guide for parts as well as what it entails to change it out. http://www.boatfix.com/appguidemain.asp

select your specific engine on the drop down menu....prices and part numbers listed as well.

Here is what it looks like if you don't already know.

If you haven't changed one before I would suggest you hack the belt if it is still intact, remove the pump off the bracket then you can loosen the bracket for re assembly.

cayjun; if you search e-bay(i hate e-bay by the way) you can do pretty good if you need the whole pump. i just found and got a new one for 275 shipped

Thanks for the boatfix link, and thanks for the "tip" about the belt, ........... I was definitly leaning that way in my thinking, ................ I have a mercruiser shop manual and had'nt found the belt tentioning bracket shown like the diagram from boat fix.

Re: 5.7 Bravo III SeaWater Pump

I was being absurd when I said $1000 to $5000. You gave us next to no information, besides telling us it was a Bravo series engine.

The impeller is a $28 part. If you buy a whole rebuild kit, it's $60 or so. If you need the whole pump, that's $300. Regardless, it's the labor required to change it that costs. We have no idea how hard yours is to get to, whether you have FI or a carburetor (it makes a BIG difference), or your boat is on a trailer (well, I guess we know that now) or in a slip, and we don't know your local area's labor rates.

I wouldn't dream of paying someone to do the job. It's mechanically very simple to do, but reaching it can be a bear, and require some dismantling of your boat. Hence the reason it's hard to "ballpark" a price.

Re: 5.7 Bravo III SeaWater Pump

jaxnjill, ................. thanks for the ebay option, ................ one of my concerns is even if and when I remove and disasemble the pump, there are so many parts inside will the parts that are damaged be self evident, will I know what needs to be changed/replaced.

So a New pump may be preferable, yet I will examine the pump, and if it's real clear whats bad, I'll attempt to fix it.

Once you have the pump out and disassembled, it's very easy to inspect and obvious if anything other than the impeller needs to be replaced. Very obvious.

Re: 5.7 Bravo III SeaWater Pump

Usually they are pretty clear. My nephew and I did mine in a couple of hours and that included removing the entire rear bench seat. I did it once alone too; just played with it for a few days after work in the driveway. One issue is making sure you retrieve or flush out any impeller pieces that have broken off.

Are you guys sure that he doesn't have a single serpentine belt? Check your serial number, but I think you need manual #24 ^^^^^ Adults Only section

I checked the Carb. & EFI for what I think is his motor....there both v belt........but I suppose that is a question best suited for cajun.

Thanks for the boatfix link, and thanks for the "tip" about the belt, ........... I was definitely leaning that way in my thinking, ................ I have a Mercruiser shop manual and hadn't found the belt tensioning bracket shown like the diagram from boat fix.

Yeah....thats the fun one. See photo for attachment point. You can't see it while the pump is in. In fact, I had to feel it during adjustment, I don't think I ever really saw it.

On the actual mounting bracket where it mounts to the block there is two (one right over the other)....lossen the top one (5/8 open end wrench, just a couple turns is all you need, it's a hard reach.) then the bottom one as well, this I did from below with ratchet & extension. on the bracket (see photo) is where the one in question mounts to. It crosses over behind the harmonic balancer and bolts into the engine block on the other side with the very bottom alternator bracket. This is where you'll get your tensioning from as it is a slide adjustment. if yours is the same setup as mine, this is the worst part of the whole thing, but very doable.

Somewhere I thought I read a 2001 . . . I must have MTHS (Multiple Thread in the Head Syndrome . . . Doh! :rolleyes: :redface:

Edit: Ahhhhh, bought the boat in 2001 . . . that would be different.
