HI PeteG
Apologies I was speaking from memory when I suggested the push setting should be pulled back. You are correct in setting it forward. Yes it is a setting used by the car racers.
The Acoms Techniplus may well be the cause of your problems. Modern ESC's are set to respond to current receivers and your Techniplus may have different pulse width ranges.
If you don't need a fast reverse you could set up with the push setting down. This may then give you the fast forward speed you require.
Hope you have a successful weekend and all works well.

HI Dave,
The transmitter is an Acoms Techniplus with, as you say, an additional push setting next to Ch 1 control stick.This may be more suitable for cars-I dont know.? At the moment it is set to the UP position and that is where it has been while setting up the ESC. if I move this to a fully down position it moves the control stick down further and limits the reverse movement of control stick. So I am not sure whether to do this.?
I might switch back to using a Futaba T2ER which has been ok with me so far.?
Today though I have replaced the motor with A Ripspeed 600 8.4v and reset the system from square one. I now need water to test properly. My post here relates only to a refurbished Fireboat - I may have confused you with an earlier post enquiring about ESC sizes.

HI PeteG
Props are either left or right hand rotation. Only really used in twin screw setups and either work with a single prop. if your boat is going forward with your chosen control stick then it is correctly wired.
I personally push my control stick up for forward and down for reverse but this is a personal choice and either will work.
Your ESC seems to have a faster forward speed than reverse. Your transmitter probably has a reverse switch for each channel and I am assuming you corrected any motor wrong direction by changing this switch. if you change over the ESC to Motor leads you can change the reverse switch to correct the motor direction. Make sure you reset your centre position between the transmitter and ESC.
It occurs to me that you may have a car type transmitter which has an additional push setting adjacent to the trim stick. if so make sure this is set towards the bottom of the transmitter before you reset.
At 20" this is a small model and weight will have a marked effect on performance. You need to ensure that the battery is placed well aft and that there is not any ballast in the boat that is not required - especially up forrard!
Do you have any pictures, and what is the weight of your model?

HI Dave,
I have been looking at a much earlier thread/post of yours regarding ESC set up.
This week I took out a refurbished fireboat complete with all new electrics for its 1st sailing. it performed very poorly, it did not plane at all because it was too slow.
I am lost with this at the moment - it has same set up -600 Speed 8.4v as my own Fireboat with a 25A esc.
On reading your post from last year you talk about motor/prop rotating in wrong direction? and the need perhaps to reverse wires comimg from ESC to the motor?
Can you tell me - What is the correct direction of rotation of prop when looking say - at the boat from behind the stern end then please.
This might be the answer to my problem as it crossed my mind that it seemed to have more revs in reverse!

HI PeteG
The general rule is twice the stall current but 1 1/2 times is usually sufficient. Graupner publish info on the speed 400 or you can use a Watt meter (battery balancer and watt meter) in series with the motor and a battery whilst gripping the motor shaft in a wooden clothes peg until it stops rotating. Do this very briefly and note the amps on your Watt meter. This is the max current the motor can draw and your ESC needs to supply this. Using a higher rated ESC ensures that the current needed will be supplied - max ratings quoted are sometimes only intended for short periods so using a higher rated ESC ensures you have the endurance to keep the power flowing.
A quick check on the web indicates a max current of 21 amps at the max voltage so you probably need a 50 amp ESC.
