Scupper valve 97 speedster

[Speedrocker19]

Hey folks. New here. Just got myself a 97 speedster twin 85s. I have a bad scupper valve. As water comes in when I’m sitting still. My research from forums say I need scupper valve. But the only thing I can’t find is how to change it or where it is even located.

I am pretty good at DIY. but wanted to see if any members here could point me in the right direction? Maybe with a picture or two ? Or if there are any threads on this topic already. I can’t seem to figure it out.

Thanks for the help!

the scupper is on the starboard side of the transom, just above the waterline. I replaced mine with one of these:

works better than the stock flapper style...still lets in some water tho

Thank you greatly. Another question. I don’t seem to have the screws needed to replace. Could you point me in the direction of what screws I need ?

To be honest, I can't remember if it came with screws or not. If not, any stainless screw the size of the ones you take out will work fine. I used some marine silicone when I put it back on.

Use 3M 5200 fast cure marine sealant for anything below the waterline.

I’ll send you guys a pic. I legit have nothing on the back. I didn’t notice. But the last guy must have ripped it clean off. And I don’t know if the one from amazon I ordered comes with screws.

That's odd...though I have a challenger...I thought they were the same. Here's a pic of my transom..scupper on the far right.

No no. Like I have a spot for a scupper. I meant the guy I got it from. It fell off and he never replaced it. Which I’m thinking may be why I’m getting so much water in the engine bay after cruising. I know it has its own hose. But on the back of the boat Legit just an open hole where scupper should be

I’ll send a pic before I put it on cause I might need help

 

[Andy Hunter]

aha! gotcha.

Any chance you could tell me the size of the screws used to screw on the scupper plate ? Like I said. All I have is a hole and screw holes where a plate did once go.

Also do you think if that that scupper hole was just totally open and under water. That that could possibly let water into the engine bay ? I know that I always get water by my feet. But do you think someone that tube that connects the floor drain and scupper hole could leak or something ?
