Probably taking my Jetworks valve off?

[douglee25]

I don't know why this has been happening, but last ride in 2005 I overheated my waterbox and cracked it at the seam. I attritubuted this to the fact that first ride in 2006, I found my jetworks valve not opening because it was gummed up, almost causing it to overheat again.

Fast forward to this past weekend.... Ski is running fine and then I let a buddy try it. He said it wasn't running right. Sure enough, I hop on it and it's running like a$$. I pull the hood and smoke is coming out.

When I got home I pulled the tank and found a rivet in the waterbox had blown out. How the hell does a rivet blow out?:banghead: Water and oil had been shooting out of this hole for some time during the day. The entire hull from the tank forward was covered in two stroke oil. I had just detailed the entire ski the week before when I had the top end out.

I'm still thinking this has something to do with my jetworks valve. I've set it up properly and it seems to open when I want it to. The problem I believe has to do with crud building up causing the valve to not always open. Watching the pisser isn't a tell tale sign either because it could totally be bypassing the stinger and just be going overboard.

Options:

1. Take out the jetworks valve completely and just run a restrictor into the stinger.

2. Put in a smaller washer or no washer for that matter to let the valve open up sooner.

3. Just run the line with no restrictor and no valve. This way I'm almost positive water is getting into the waterbox.

Thoughts?

just find a T with a 1/4" pisser going down into the waterbox and run that, see how it works. i've run boats without the valve and the smaller line routed into the stinger, and they ran very nicely.

Just to clarify, you're saying run a 1/4" line to the stinger, not a 1/4" pisser fitting?

I run a 3/8" ID line to the stinger, but have an old 2.0 seat (from a carb needle & seat) stuck in there next to the tee fitting. It lets in just enough water to keep it quiet, while keeping good off-idle response. Yes, I read that back on the ~other~ sire back when.:cool2:

The carb jets can clog also.

I use no washers in my jetworks valve. That should stop water from going thru it up until 3000 or 3500 rpm's.

I am becoming a firm believer that all water going thru our skis should be filtered first anyway.

I'm running a dry pipe so the only thing that can clog mine is sand in my water, no gump.

I'm starting to think a filter may be a good idea as well. I want to say I have an 1/8" washer in it currently?? Maybe I'll run it without the valve and compare the response to with the valve. If it's not very noticeable, I may leave it off as a safety factor. I can not afford to be cooking exhaust hoses and waterboxes twice a year.:bs2:

correct. just find a T fitting that is 3/8 -- 1/4 -- 3/8

the 1/4" fitting is the bottom of the T. if i'm not mistaken, the stinger is already a 1/4" fitting, isnt it?

i run a dry pipe also, and i run strainers/filters at both cooling lines just after the bulkhead, before the water goes to the head/manifold/water inj

Got it. The stinger should be 1/4" (3/8"?). I forget offhand. What strainers do you use? Do you have to clean them often? I suspect that if you do a lot of ocean riding that sand must clog them up pretty quickly, no?

you shouldnt have to change the strainers that often at all. i ran aground in st. augustine, so, i just changed them out after that last trip there, but unless you do something crazy like that, they should last a long time.

Ok, but what kind of strainers do you run?:biggrin:

Its funny. A small sea strainer at the bulk head never seems to need cleaned on my ski.

I check it but it is always clean. I beach my ski constantly but it seems like anything that gets caught by the strainer just flows back out to the pump.

The only time I clog now a days is back at the 90 off of the pump. :banghead:

But usually I can just disconnect something up top and blow back thru and I'm good to go.
