Yeah, those Castle motors are monsters. The 1717 that I have on an outboard was initially air cooled and it never got hot even pulling spikes over 180A.

You are probably right that some motors run very cool & you might get away with no cooling ok, But a lot of motors especialy some of slightly cheaper ones run very hot indeed. Not sure if this is down to their design, build quality or inferior materials or all 3. I watched a guy on sunday run his brand new first time on the water DF 25" knock off boat with a fsd 380 motor had the motor seize solid on its 3rd short run. Total run time around 3 minuites in total for all 3 runs, Motor was extremally hot with water cooling working ok & on fairly small prop doing around 35mph. Im tempted by the spartan but an concerned about some of the side to side roll ive seen but that may just be incorrect set up & trim. It will be interesting to see how the hull runs going well past 50mph so i think ill wait & get more feed back as its very early days but first impressions seem very good & their close to delivering on their 50mph out the box which we probably all had some douts to whether it could delivered but looks like it will. So fair dues to Traxxas. Thanks Martin.Comment

Water cooling a RTR boat should only need the single pickup. Most boats really only need one. I ran a single rudder pickup in a HOT setup twin cat. Worked just fine. You can simply just add a T or Y connector to split the incoming water.Comment

I agree 100% that 1 pick up is enough for most boat especialy rtr boats for cooling, The point i was making about having 2 is if you do get a blockage in one & dont notice it youv halfed the odds on potentialy damaging both the esc & motor as one will still have water going to it, Just a bit of extra insurance on expensive parts & no down sides really on 2 pick ups. Thanks Martin.Comment

make sure the opening is good
I use a point file on my SV rudders to open up the inlet, and I get possibly 50% more volume going through the system
My SV motors with big props like a CF48, never get above 125*Last edited by Brushless55; 01-10-2011, 07:16 PM..NAMBA20...Caterpillar UL-1, P-Spec OM29, P-Mono DF33, P-Spec JAE, Aussie 33" Hydro-LSH, Sprintcat CC2028 on 8s, PT SS45 Q Hydro, PS295 UL-1 power, OSE Brothers Outlaw QMono 4-sale, Rio 51z CC2028 on 8sComment

One of the better video's so far, looks like it handles really nice on 4s and is pretty quick. Was that still about 33 mph like the data showed?Comment
