Water cooling problem

[Jlov]

I am having a problem with water coming out my water outlets. Now I know how I just burned up my Swordfish ESC. I just ran my Popeye and noticed I didn't see water coming out either outlet on sides of boat. If I flush boat in back yard using my engine flusher water comes out both sides of boat. If I blow thru both water tubes that bring water in thru transom air comes out both water outlets. If I blow thru both nipples on rudder air comes out holes on bottom of rudder. So what could possibly be stopping water from flushing thru everything when boat is actually running in water?.... Any suggestions please. Thx Jeff

rudder water pickups aren't great and those holes
in your rudder look awful small.

The holes in the rudder should look like this.

Work on that rudder a bit with a round file and see if that won't work for you.

Sorry you lost a ESC.

Who makes that rudder?

or add an auxiliary water pick up.the lower water pick up on my rudder was added for better cooling. Gill

It's Kintecs rudder dual pick up rudder. Used this type of rudder on last Popeye and it worked fine. If I put bottom of rudder in my mouth and blow air comes out the two nipples at top. Does anyone know who else makes a dual pickup rudder? Thx Jeff

Gill, what is that brass fitting near the strut bushing for? Looks cool, is it for lubrication?

[Jlov]

Actually Doug thatsba Speedmaster bracket I have on Popeye and just noticed your link is Speedmaster products and they have a rudder I can use. Thxxxxx Jeff

Jeff, I had the same exact problem with TFL's single pick up on my Popeye, now I know why the motor was always hot, everything I did on land indicates good flow, but once it is in the water, there is very little coming out of the outlet, I just checked my pick up holes, it is a bit longer but not by much, guess I have to elongate it too. BTW, the only other rudder with dual pick up is a Speed Master, huge rudder though. I had to cut it down for my Lizard Xtreme.

Ok thx Tim that helps. Never checked my other one that was on the first Popeye. It probably was doing same thing as my motor in that one was always hot to. I have the Speedmaster rudder that came with the bracket I have on there but it's a single pickup. I'll just have to order the dual pickup one. Thx Jeff

OSE has a good selection of hull mounted pickups.
they work a lot better and shorten up your lines too.

It's a hydroplane, he could only use the transom mount type, which would cause unnecissary drag.

Jeff just get the speedmaster rudder that was intended to be used with your bracket in the first place.

That looks an awful lot like the rcbb rudder..... which did indeed also turn up at Kintec as well. If I remember right..... some people trying those rudders out on hulls other than those they were designed for, found that they had to be very careful the pickup holes were actually submerged during runs. Some people were highly suspicious they weren't. Just a thought.

Had that rudder on my Zonda cat for a while. Picked up water ok. I know RCBB does nice dual pickups. But the speedmaster ones are good kit too.

second part of your response makes sense. first part not so much. what do you base this statement on?

i would contact kintec and ask them to get those pickups modified. and post their response. forums are a good way to warn potential buyers of garbage hardware. just make sure you have gone through every inch of you your water system to make sure there are no blockages. there is no need for this kind of mistake in manufacturing. why change something that has worked great for all these years.

I am new to fe boats but have been running nitro boats since the mid 70s.
keeping the cooling system as short as possible has always worked the best.
adding extra tubing to get back to the rudder plus the length of the water port
inside the rudder makes it that much harder for the water to flow through the system.
jeff said he blew air through the rudder. if he would hook the entire cooling system
back up and try to blow a mouthful of water through it I think he would be surprised
at how much force it really takes. I'm not saying rudder pickups don't work,but having
a shorter cooling system works better.
