thanks Dave i got a seaking 120a watercoold brushless ESC by Hobbywing which handles the power well. Same motor as before got a 38m 2 blade prop looking for a 3 blade. i was originally useing the 12v battery to run the motor but it was no good now use a lipo which i have installed under the deck in front of the motor.the large battery is running the watercooling pump and is also the prefect weight for ballast.NO problems with the salt water as i have got stainless steel, brass and copper fittings and a good flush threw the cooling system with fresh water. might be some time before i can put up a video because the council is draining the pool next week for the annual winter maintenance which is a bummer as there other suitable ponds handy.
cheers Allan

FINELY got my Perkassa running this afternoon after spending about $200.00 on new ESC, prop and stainless steel coupling
( the plastic one shattered on the last run in about 2 seconds). I have got to much power in it but the boat runs at about scale speed on about half throttle. I am running in a saltwater swimming pool on the beachfront at Wynnum Central which is a bay side suburb of Brisbane Queensland Australia.
Cheers Allan

Thanks Jarvo Ihave a 40mm 2 blade prop and the motor was running at high speed for about 1 minute. My swimming pool is to small to run a large boat at speed in, that was why a was holding it. Yes it was very hard to hold the boat at the time there was a lot of power, as you said it my have been overload because the boat could not move. Next time i will take it down the pond where i used to sail. Cheers Allan

Yes Dave I had the boat in the swimming pool and holding it stationary. The water pump was running with a good flow of water before and after the fire. I just had a thought maybe there was to much turbulence from the prop around the water intake which is behind the rudder stopping the water flow when the motor was running at speed . I couldn't see the out let as it was on the side away from me. Maybe i will have to move the inlet or something. Cheers Allan

BIG MISTAKE I brought a 5300mha -50c-14.8v-4s1p-78wh LiPo battery yesterday. Bloke in hobby shop checked my ESC which is a TURNIGY AQUASTAR Watercooled ESC 160A. and said that it could handle that size battery. Giving the boat a test run this morning the ESC erupted in a huge cloud of black smoke. Not happy Jan will be ringing the hobby shop in the morning.

Thanks Dave I have a pump for the water cooling so it is running separately and has a good flow of water. I did have a 3 blade plastic prop but a blade broke off when i ran aground at high speed the 2 blade prop was doing ok when i had the old motor in.As you said earlier I will check out the lipo battery and see how it goes. Cheers Allan

G/Day All Thanks for all of your advice. I have a 2 blade 40mm prop and the shaft is running free. i originally running a Johnson brushed motor with no problems with power except it and the esc i had got extremely hot. i could not find a water cooled brush motor so that is why I got the brush less motor. it is very hard to get model boat parts in Australia. Maybe it might be easier to put the old motor back in, i have now got a water pump so i maybe able to make a cooling system. Cheers Allan

G/Day I have not got any idea about electronics. I have got a 47 inch Perkasa Patrol Boat running with a single Brush less Turnigy 3974-2200kv water cooled motor and a water cooled Turnigy 160A ESC running directly from a rechargeable sealed lead-acid battery RL1270(12v7.0Ah/20hr). My problem is when the motor is running at high reves it cuts out after a few minuets. Is this from low battery or wrong setup? All the help i can get to get my boat running smoothly would be much appreciated . thank you. Allan
