I don't have the Quicksilver generator, but it could just be a bad hose or a crack in the muffler. If the exhaust hoses are original to the boat, I say it is time to replace them anyway.New problem-I think I have an exhaust leak from my generator ( QS-7.5 gas). I ran it for a minute last night with the Engine room open and the area immediately filled with exhaust. I checked the exhaust hoses and they seemed fine. I don’t have easy access to the back so I didn’t have a chance to look at the exhaust manifold. There was no coolant in the coolant reservoir. Have any of you had this problem? What did you do to fix it? I’m having the marina replace the starboard transmission this week so I’ll probably have them address this issue as well.
Considering selling our current 2000 340 Sundancer to purchase a 1998 40 EC. Wondering, does the table in the cockpit drop down flush to the wrap around seating to form a large sunpad?
Thanks. The hoses and muffler are new. I noticed there is a large puff of smoke from the back of the gen on start up. I also noticed today after it ran for about a minute with a normal amount of water coming out of the exhaust, something changed and the water stopped at the exhaust. I also noticed water leaking in the boat. All that means I’m going to have to get behind the gen to see what’s really going on.I don't have the Quicksilver generator, but it could just be a bad hose or a crack in the muffler.

I would say so. I hate to say it, but you may have a cracked exhaust manifold. That would explain the puff of smoke and the water leaking in the boat. When the water fills the muffler, it comes out of the cracked manifold because it can't overcome the pressure.Thanks. The hoses and muffler are new.

Well I was able to identify the problem and even get a good picture. Now I need to find a parts breakdown to see how to fix it. It looks like it may be a pipe nipple that has rotted and broken.I would say so. I hate to say it, but you may have a cracked exhaust manifold.

I will keep my fingers crossed for you that you can get the remaining pieces of the pipe out of the manifold. Maybe use a brass pipe nipple instead of galvanized so you don't have the issue again down the road.Well I was able to identify the problem and even get a good picture.

Thanks. When i got home last night i was able to find the original documentation for the gen, and a previous owner had noted that the exhaust manifold and exhaust outlet were both replaced in 09. Hopefully they are both salvageable because they are very expensive.I will keep my fingers crossed for you that you can get the remaining pieces of the pipe out of the manifold.

That is assuming you can even find them anymore.Thanks.

So...has anyone had to get behind the Generator to work on it? It looks like I might be able to get back there by crawling around the Port side. Just wondering if I'll have any room to work back there.
I don't think the 400 has the same access. I had the rear seat out Tuesday and the generator is aft of the hatch that I found. I hope I'm missing something.The 390EC has a rear bilge hatch under the rear bench seat. It provides easy access to the rear of the generator, water tank and holding tank. Doesn't the 400EC have a similar hatch?
BTW I thought I read somewhere that the Quicksilver generators use a Nissan engine. If so some parts may be available from automotive sources.

Using the hatch in front of the bench and generator, you get into the space between the stringers with the batteries and fuel manifolds around you. It gives good access to most everything around there, including the generator.
I found the best way for me to access anything on the back of the generator is to unbolt the generator from the stringers, disconnect the exhaust hose and spin it in place. That is how I was able to replace the main oil seal under the flywheel of the generator when that went bad. It may have been easier to remove the generator from the boat, but I was able to do everything on my own.
By the way, I have a Kohler 5E in my boat as the original Quicksilver generator was a giant paperweight when I bought my boat (frozen from corrosion).
PS, I thought I had a picture of the generator with me, but I do not. I can try to take one tonight when I get home so that you can see how mine is positioned and what the access looks like. I am sure it is the same as yours.
