Yeah I watched the vid.It looks good.So those were the 4818's?It looks good and stable.I got to watch Docs now and I'm getting mine from yesterday up from the Shocker.

Nice to see her hit the water! Looks like she rides nice and flat

Regarding the cooling issue, are your temps high or are you not seeing water exit flow? Here is a link to a HPR115 build that I used as a guide for making my through hull inlets. The photography is some of the best I've seen for a build thread. Then again, I've noticed that Manuel doesn't bother with angling his water inlet tubes. His are basically vertical with a teardrop added like yours. If you have an adequate teardrop, you're probably fine.

If you're having trouble blowing through your cooling circuit, maybe you should check out the motor water jacket issue found in the link above. The water fittings were threaded too deep and impinged on the motor can - restricting flow. I'm not sure this is even possible with your LMT jackets since they don't look threaded, but thought I would mention.

Thanks gator, I have read that thread a while ago. Motor jackets are fine, no problem there, but tube is only 3mm and teardrops are/were small. I have now sorted the teardrop so will see how it turns out. If all works and can keep her cold, I'll hook up the 8s for some real fun.

Oh didn't really see any water flow from the exits

Looks good in the water Kent. Hope my maiden goes that well! Great job. FYI, I hooked up my receiver to the MHZ antenna and it works flawless.

Wunderschönes Boot.Super edel gebaut.Einfach der Wahnsinn.
Wünsche dir viel Erfolg bei der Erstfahrt.

Looks good !!! For the cooling problem if i remember correctly I think the tubes need to be angled a bit more. They seemed a little straight when you first did them. I will try to get some pics loaded with the pickups that I had. The only problem is the two boats they were on I sold. I should have some pics though

[nata2run]

@ Charles, YOUR ALIVE!! And thanks for the compliments. Of cause you will have a good maiden as you have invested a lot of effort in this build. I wish you all the best, and please.....get that boat done before Xmas.

@ Christian.... What can I say, your builds have been the number 1 inspiration for my builds, and here you are complimenting on my boat. I guess only thing to say is ... Thank you ... DANKE

(Christian .... Was kann ich sagen, Ihr eingebauter waren die Nummer 1 Inspiration für meine Boote, und hier sind Sie auf meinem Boot Komplimenteren. Nur, was ich sagen kann ist ... Ein großes DANKE)

@ Chris hopefully it will work after making the teardrop a little bigger. If not then I'll replace it with a proper under hull pickup. Don't know what possessed me to do it this way when a had a great success in installing in the other hull.

Shawn, I think it a combination of small hose and "short teardrop" I have made the teardrop longer, so before I change the tube I'll see if it has made any effect if I change it all and no good then I'll turn to the metal ones that I know work. Did you watch the vid by the way? The doc has some more coming once it uploads, but I think his still on a 28 modem LOL

I upload slow because I know you like waiting ...

The Mystic had water flow, evident on my vid , but the motors returned as egg cooker cans.
Hopefully higher voltage and lower amp draw will result less heating.
The pickup teardrops were small .. more suited a small boat.. this cat needs LOTS !

FYI, these sf240hv esc cool by both air convection and water passthrough.
Kent has his esc wrapped in 3mm insulation squished between cf tray and deck.. not good for cooling the unit.

"Kent has his esc wrapped in 3mm insulation squished between cf tray and deck.. not good for cooling the unit."
Not wrapped just edges so they dont slide, there is still air between all the parts for airflow. I even made room for a fan if needed

please ask if in doupt of how things were made.

[drwayne]

Silly of me to consider anything encapsulated in insulation could be heat intolerant, that's all.
Bedding( air pocketed )quilts keep you warm.. how does that work ?
I did notice the esc wrap was cool.. either sheilded my inquiring poking finger from heat, or suggesting the motor poorly cooled as second in line....
If the esc was at that temp there would have been smoke on the water .
She needs more flow.

[nata2run]

She definetly need more flow, carbon plate above ESC's was a little warm but nothing to worry about. I have this feeling Lehners run a little warm, correct me guys out there if not true? but I seem to hear it alot. That ofcause is no excuse for me!! Hello everyone, my name is Kent, I have a cooling problem.... LOL

[Chrisg81983]

kent admitting you have a problem is the first step lol

[nata2run]

Your suppose to say welcome Kent!!!! we're here if you need to talk LOL

[srislash]

I'm here if you need a hug

Don't worry you'll figure it out.I found out I hooked up my cooling tubes wrong on one of my ESC's today and it almost thermaled, so you are not the only one.One side also does not flow so good(motor cooler).
