Speedster 150 Exhaust Touching the Hull

[MacSeaDoo]

Just a recap to maybe help someone else out with the same problem...

I bought a new to me 2011 Speedster 150 255HP this year with only 55 hours on it. From day one, there was always water in the bilge and through troubleshooting I determined that it was coming from the exhaust somewhere. (The water was hot) I spent alot of time trying to find it and in the end as it started to get worse, i found it. Basically the exhaust can was touching the hull in the corner and it wore a hole in the exhaust.

I had the hold welded and now have no more water. When I put it back, there was no position when installed that would stop it from touching. I put a piece of rubber between it and the bulkhead and figured I would sort it out in the fall.

Fast forward to last weekend. My SC started making noise. (Bad bearing) so I pulled it all apart again. I also decided to fix the exhaust issue.

To summarize:

• The flex hose was installed to far down the exhaust inlet. This brings the exhaust almost 2 inches closer to the engine, resulting in it touching the bulkhead.
• The previous owner gave me all of the service paperwork and I don't see one mention of it, so I am assuming this was done at the factory.
• You can see on the exhaust that there is a depression around the exhaust where the C-Clamp should be installed. Mine was another inch or 2 beyond that.

Again, posting to help others to make sure their exhaust is not touching the hull, or if you have hot water in your bilge but can't find it.

Cheers,

BTW, for those wondering what the exhaust can looks like on the inside and what baffles are in it.

• Basically the can is empty less a raised passage way at the bottom almost the full length of the can.
• The pressure forces everything to the back then the water goes down the raised passage way, which is the only exit point back towards the exit to the raised loop to the waterbox.
• The stand pipe do to the angle prevents water from coming back up the manifold.

Thanks for posting, hard to believe it did that much grinding in 55 hours. Guess that fiber glass is more abrasive than I thought. I know it is heck on the ole hands when playing around in the hull. I replaced my bilge pump and throttle cable the other day and dug fiber glass splinters out for days.

Here it is installed properly.

You can see previously how the flex pipe was installed too far forward and where it was touching compared to where it is now.

Yeap looks like you got a good 1/2-3/4" out of it.

Yes, pulled the bilge pump too. What a great idea it is to basically rivet the cage to the floor right up against a bulkhead. Especially when the only way to remove it is to squeeze both tabs in to release it with one of those tabs unreachable because of the way it installed.

I had to drill the old rivets out and replace the whole bilge pump. I tried to glue it back but couldn’t hold it long enough for glue to set “ its a long way down there”.. Drilled new holes and new rivets..
