2006 Sea Doo Speedster water problems

[ozarks]

New to the forum but have a question that maybe someone could help out with?

I recently had a new 4 tec 215hp engine put into my Sea Doo speedster 150 by a repair facility and I took it out on the 4th of July.

When underway and running down the lake I did not have any water issues, but upon anchoring out for approx. 2 hours I noticed water in the floor of boat and I jumped in boat and the bilge area was full of water up to the engine 3/4 of the way. I kicked the bilge on as the float switch did not kick on, but it would not keep up with the water coming in from sitting there in the water (we were sitting on the back of boat at swim platform area).

The boat had to be towed to dock as we feared it was going to sink. I have no clue where water is coming from and fear it is coming in thru the rub rail potentially as once we got water out, I backed it back into the water and at the rear of the boat and keep in mind the angle it was at from the ramp, I thought I could hear water coming in.

Can anyone tell me, first could this of come from incorrect installation of the new engine or what else would you recommend to look at.

Help would be appreciated!

Shaft seals? Poorly sealed rear platform seam? Bilge pump should have cleared any of those issues and prevented a panic towing.

Send the fatties forward & see what happens!!! LOL I know that's politically incorrect, but WTF.

While on your trailer with the drain plugs in, you should be able to use a water hose and fill induce water into the bilge.
I am relatively new to the Sea-Doo boat world; however, it stands to reason, where ever water is getting in, it should also be able to get out...thus showing you the location of the problem. For suspected smaller leaks, start with a dry external hull, with a water filled bilge use a paper towel to simulate washing the hull surface.

My bet is that your service center will need to correct something they didn't quite seal correctly when they installed the new engine.

For future reference; I always run water into a bilge to test for leaks after anything has been done that could result in a seal/leak/failure. I never want to find the problem at the lake.
On my recently purchased 06 Sportster, I found a thru the hull screw hole that was simply missing a screw. Something was removed and they didn't close it back up. I used the current hole and added another for a Hummingbird transducer.

I would suspect that you probably have an issue with your drive shaft seal as well which is where I would start. There have also been issues with water entering seadoo boats through badly sealed hulls in the seam under the rub rails.

If it is the drive shaft seal is leaking it should be apparent when the boat is put in the water, if it filled up your hull as fast you indicated. Could a problem stemming from the recent engine install if the engine is not properly aligned with the jet pump the drive shaft could quickly ruin the drive shaft seal from misalignment. A close inspection of the carbon seal should indicate what if anything is wrong.

To test the seal under the rub rail you can back the boat into the water from the ramp with the back of the boat tied to the trailer so it will not float off. Slowly back down into the water until the rub rail is under water and have a buddy keep any eye on the engine compartment to see if any water is pouring in. If so, just seal it up. There are some threads about this.

I would say driveshaft seal but you would have seen water pouring in from there. On mine the rub rail in the back was leaking from some missing rivets. You can see from the pics. I only noticed the leak when fixing other issues with the boat still on the trailer which made the back end go under the water. Sounds like your issue as well.

A common leak for many of the boats is, the rear rub rail area as it is under water in many cases even when empty. How most find the issue is, leave it tied down on the trailer, make sure your plugs are in, back it down the ramp to where the rail is below the water. Many have seen it pouring in.

The boat is designed to self bail bilge water when moving forward. Would the boat not start? Why did you tow it? Did you pinch the "Tow" hose when it was towed? If not, did you get above 15 mph or so? If so, you probably put water into your engine. Have you cranked or restarted the engine since?
