New UL-1 Water Jacket

[Kfoss1]

It apears that the 3 piece water jacket on the UL-1 is going to be problematic. The motor measures 1.430 so your upgrade SV jacket which is 1.412 won`t fit. Is it possible to add a glass or aluminum sleeve this size to your catalog? I`m sure it will be a popular item.

Since the leak is so easy to fix, why replace the jacket? Oh well, it's your money.

What`s your recomendation for a fix?

[Steven Vaccaro]

I will have a new jacket once we have some replacement motors to test them on.

[Jeff Wohlt]

Yes, what is the easy fix, Jay? Silicone it up? Use larger O rings or what? Not sure why a three piece was designed.

Will the Pro Boat jacket fit? What is the can size of the ProBoat BlackJack motor?

Checking my notes..yada yada yada.. ho hum reading……….


Notes about the cooling system on the UL-1

Reading……..
The system blows the lines off at 60PSI..

Grimracer says… if you ever have a line come off either replace it with fresh line or drill a small .032" hole in the back of the rudder blade to relieve the pressure. Or.. use what ever system you like.. clamps.. you get the gig..

Reading….
Looks like the testing I did what at 30psi
Grimracer says.. If you like you can pressure test the system to 30PSI. Use dish soap and a acid brush to cruse any areas that might leak, brass plugs, nipples, O rings..

Reading……..The few that I found the brass plugs leaked. ………I could not tighten down the plugs and make them stop.. A small dab of SI fixed them..

Lets see……. Reading on…..

Looks like we have addressed this with the MFG but it looks like daddys going to have to make contact again.

Grimracer SAYS…….ROCK ON!

Mine leaked just by blowing on the exit tube with a finger on the rudder hole. We tried tightening the rings and repositioning the sleeve and it still had a cup of water after only 8 laps around a short course. The leak was from the threaded area which I found very loose feeling. Silicone or plumbers tape might work, I just didn`t try it. For now I`ll use the silicone SV sleeve till Steve is able to get some made up.

Tightening the rings could have made it worse.. You see..

The O rings become captured between the center barrel and the end caps. I have found that oiling up everything and wha-la.. you can feel the point where the orings start to compress. Over tighten and you can fail the system..

Without the o rings touching (or not in place as it would be) the end caps free spin on the barrel threads.

I think I fixed the problem. Ace Hardware had a #56 O ring (smaller diameter and thinner) that fits perfect without bulging. I had to slide O rings on motor first, then install endcaps. I used a little dielectric silicone grease to seal treads.

ROCK ON!

Do not overtighten end caps or they will SLIP ON THREADS (loose tolerances).

While reassebling my water jacket onto motor (using my # 56 orings) I ended up using three "very small drops" of Blue Loctight placed evenly around threads on each end of housing. While Loctight was still wet, I then lightly installed the caps so they where just touching the Orings. I allowed the Loctight to dry for 45 minutes. I then twsted down the endcaps a little further for a good water tight seal. The endcaps are a little harder to twist down once Loctight has dried, but no slippage so far.

Clearly, there is an issue, you see, perhaps an addendum to the instructions would be in order offering those words of wisdom. Additionally, tightening the caps seems to me like an obvious solution absent any instruction to the contrary. Given, it is billed as rtr and we as consumers, perhaps unreasonably, expect more from AQ.
