Excessive Hot water in bilge, took 5 minutes to drain out speedster 150

[fourty6]

My first time out in my 2009 speedster 150 255 hp. After a few hours we noticed water in the ski compartment where there wasnt any when we first launched. I checked the bilge and water was present also. Went to restaurant and had lunch while boat docked. No more water accumulated during that time.
Ran it home about 10 miles at high speed. A little more water accumulated. Pulled it out, removed drain plugs and very hot water drained for at least 5 minutes.
This is my first jet pump boat, ive owned 7 stern drives previously. Would love to get a cooling system flow diagram or shop manual so I can identify the parts to check for leakage. Or if anyone has a solution I would really appreciate it. Im afraid to take it out again until its fixed
thankyou ahead of time.

can be alot of different problems, first thing is your bilge pump! is it working?
could be the carbon seal or leaking exhaust somewhere......
do a search for "water in bilge" there is heaps of recent posts on this problem.

Above post is accurate. Carbon seal is easy enough to check. The water could be hot for no other reason than being inside the hull splashing around the hot engine and exhaust.

If it is SUPER HOT, then you need to look at the exhaust for a leak.

Agree, your bilge pump must not be working?
I'm not sure if there's a shop service manual for any boats, you might locate one somewhere. I haven't found a shop manual for my 2001 boat so I use the jetski manual b/c it's identical in many aspects. Could be something as simple as a lose hose clamp somewhere, I had a small leak in one of mine on the first splash last spring and it was quite lose when I put a nut driver on the worm screw clamp.

Here's a link though, to the electronic parts guide (boat specific) that might be helpful:

No the bilge pump dont work. I will fix that asap. But I cant imagine the amount of water that was in there from just riding around for 4 hours. Ive had boats all my life and have neve r seen this much water in a bilge without there being some type of problem. Im just not familiar with jet boats thats why id like a service manual.
thanks for the parts callout. It at least give m e an idea to identify some stuff there

As opposed to flying blind, you definitely want to get ahold of some form of service manual that closely or exactly matches your boat, preferably one published by BRP factory service. These manuals include valuable detail thus are indispensably importante to have, IMO.

46 for short ,
If for no other reason put the boat in the water but still on the trailer. Deep enough to suck water into the jet pump area. Start it, warm it up and see if you find any water coming in from carbon seal, leak in exhaust pipe, or other areas...rev it up a bit if necessary. Post back up what you find.

Hi 46
All posts are correct. carbon seal or leak in exhaust is what it sounds like.
Good that you found bilge not working.
I would also check all cables that go though hull i.e. steering, reverse.
i have shop manual for 180 might give you something to go off if you can't find one for 150.
PM me if you would like me to email to you

I have a 07 challanger and I'm having a water issue...no leaks on the exhuast system or any through hull areas...the hot water is from hitting the exhuast and the bottom of the engine block...I bet it's set up like mine where water collects under the engine in that v spot...bilge pump helps but doesn't get all of it out...next time at ramp and your not being rushed back it down and get the front of the boat as high as you can and drain it...make sure drain plugs are out...water test it and see how much more you get..
Do you keep boat outside? Do you have a cover for it? Do you wash it after you ride?
Check out my post..called I hate it...I'm working on fixing all these spots...

 

[Coastiejoe]

Many of the boats have leaks at the rear rub rail where the molding covers the seam up. You can test this by backing down the ramp, leave it tied to the trailer, see if water comes in from the rub rail area, (this is where the two halves of the boat are seamed together).

 

[fourty6]

I found the carbon seal in a diagram on internet. How the heck to you get at that? Pull the Motor? Or take apart the jet pump?

 

[pete63]

via the pump. is it leaking?
search on this forum for carbon seal, there is heaps of stuff, even a how to.....

 

[Sportster-2001-951C-Stock]

Here's how I do mine, but of course I don't know exactly what yours looks like:

To replace the carbon seal (and the rubber bellows that holds it along with perhaps the stainless rubbing ring) you first remove the c-clip that retains the stainless ring and slide the ring towards the engine.

Push the stainless ring into(towards) the rubber bellows which compresses the rubber bellows further, until the c-clip is exposed and you can remove it from the groove on the drive shaft.

Then AFTER that, remove the jet pump, replace whatever parts you need, reassemble.

BTW, you need to do a water test to find exactly where the water is coming from else you're just shooting from the hip. Normally if there's something wrong with the carbon seal you will also experience a reduction in jet pump performance b'c air will leak from the bilge into the jet impeller and cause impeller ventilation (like slipping, not gripping and hooking up with the water).

I think it's wise to examine the upper to lower hull connection, often it can be repaired from inside the hull if necessary else the rub rail will need to be removed, ie: the rivets drilled out.

I wouldn't expect your rub rail would leak while underway as it seems you described, nor would I expect your carbon seal to leak while under way that much either.

There may be some detail I'm not considering for your particular boat thus this post is free of charge and does not constitute a binding contract or warranty in any way.

what i would do for the highlighted reason, mount a gopro or cheap waterproof video camera down there pointing to the hull and carbon seal area and go for a ride. this way you will pin point the problem or rule out a particular item.
if the carbon seal is leaking that bad, you will normally get some cavitation going from 0 to wot.

 

[Sportster-2001-951C-Stock]

Yes, and absent the gopro camera backing the boat down the ramp and running it on the trailer is how I locate many leaks. I've also tied boats off to a large tree using a heavy rope and run them stationary that way in case the boat ramp is too busy.

Of course this means I climb down into the bilge to inspect for leaks while the power plant is operating, might be a good idea if this is your first rodeo to have someone at the helm while doing this in case you slip in the bilge or something they can shut it down.

Always have a multilayer backup plan when it comes to marine safety, there are a lot of "gotcha" situations.

Wow this forum really works! Thanks to all of you for all your great ideas. Im a small business owner and have an important project to accomplish AND im a good husband and have a few promised honey dos to get done before I work on toys but in the mean time im going to read the manual and learn about the working of this thing.
im very exited to get this boat in the water.

That line I made bold type is the smartest thing I've heard here in a long time....Congrats on wanting to take the time to read the manual....you may want to read it a second as you are working on it......sort of like matching pics on the boat to the pics in the manual.

Hello fourty6,
I have a 2003 Speedster 150 155Hp and I was facing the same issue this year in spring. The Speedster 150 is a boat where you always get wet and you always catch a lot of water. If you get a lot of water inside the boat, it’s supposed that it will leave the boat via the drain hose at the stern. But if you open the ski-locker or the sealing isn’t properly it will pass to the engine compartment. Once there it’s getting hot and if it’s filled up enough it will leave the boat via the bilge-pump. But if your pump isn’t working it stays there until you’re back at the ramp. And trust me, you can fill a lot of water in this bilge. Our bilge-pump was running permanently for approx. 5 minutes after we had eaten a couple of huge waves from other bigger boats when we where in the Lake Garda in Italy.
Just thinking back how many water you caught during the last driving and if you remember that you where wet, it might be not something serious. But check your bilge-pump since this is essential for keeping the water level in the bilge as low as supposed.
And have fun with your Speedster ;-)
