I have an 84 S/N 2001. Just had impeller replaced and several other things changed as well. the last time on the water I noticed that I had to run the bilge pump a lot more and longer that I ever have. When I got the boat back it was taking on even more water than before. My thought was if the water is leaking in while in the water then I should be able to pour water into the hull and see it leak out as well. Didn't happen. Now I need some suggestions. The boat sat at a dock tide up for about 2 hours, and I had to run the pump then for about 10 min, to get all the water out from in the hull. Water inlet has been replaced, all hoses, inlet filter is new, impeller is new, where else can water get in?

Thank you, I'll check the rudder and the exhaust. I've already checked the prop. Hope it's one of those.

I was de-winterizing and re-installed the impeller in the raw water pump. The three screws holding the case together are apparently slightly different lengths. I put the longer one in where the set screw for the internal pressure thingy goes and happened to bunt the screw a tiny bit. Thinking nothing of it at the time I carried on. When running I had this dripping water coming down from the area. I immediately thought gaskets. So I gasketed both sides of the in-between plate thingy. Still dripping. Then I remembered the screw and tightened it. Still dripping. So I tried plumbers thread tape and that got it. Of course I had already used the shorter screw in that spot. I think I should also probably remove the gasket from the o-ring side.

Have you found your problem? My '83 is doing the same thing. I think it is the exhaust.

It was the exhaust in my '80 Ski tique. 30 years is a lot to ask of heated rubber.

How hard of a job is it to change the exhaust tubes? And where would I go about ordering such things?

I think they're generically called wet exhaust hose. I got some from a hose supply outfit. Buy it by the foot and cut it to taste. Simply cut the old ones off if you're replacing them anyway. I used dish soap to lube the hoses to slide them on. Slide them on as far as you can and then position the hard pipes and slide the hose back down onto the hard pipes. Same idea for the connection to the muffler. My 96 has 2 up at the risers to the hard pipes, 2 after the hard pipes to the muffler, and one out the back from the muffler. I got the hard pipes from my local dealer.

Mine was leaking from the portion connecting the mufflers to the thru-transom exhaust outlet. I tried it without pulling the fuel tank out, but ended up being glad I did remove the tank. 30 years is a long time for fuel hose, too. You may as well take advantage of the situation and replace those as well. Its a great time to get all the dirt/trash removed that may have gotten in. And while the tank is out, before you remove the wet exhaust hose, you can test it in water to see exactly where water enters, and rule out the rudder packing perhaps. Nautiqueparts.com had everything I needed. Nice folks.

This may be asking the obvious, but are the speedos working? I have had a speedo rubber hose become disconnected and when moving the tube shoots water into the hull. Just a thought.

I finally got around to tracing the exhaust water leak problem in my boat. At some point the mufflers had been changed. Whoever did the work did not double clamp the first meeting of the 3" hose and the mufflers. So I took them apart, bought two new hose clamps, put it all back together correctly and now it does not leak water.
The $4 fix was way better than what I thought I was going to have to do!

Brad,
I'm glad you fixed the issue but be aware that double clamping was not the problem. Single clamps below the water line have been used since "day one". It hasn't been until recent years that the USCG regs requiring redundant clamps was added. The bottom line is whoever changed out the mufflers was a big time HACK!!!

One of my mufflers had developed a hairline crack. I used fiberglass to make the repair. My pitot tube and hoses are shot. Have not worked since day one. Any tips on how to fix and where to buy. I remember being told they are NLA.

I bought my hose at a local marine shop. It was actually cheaper than ordering it online.
