After its last outing my Zwarte Zee, built over 25 years ago,finally decided that the windscreen washer pump used for the fire jets was not going to do any more pumping. To dig it out of its hiding place under the foredeck meant a fair bit of dismantling, so took the opportunity to upgrade the RC to multi-channel 2.4ghz from the old 2 channel 27 mhz. The old 2 channel required using the extreme rudder tab to provide the pump connection as in the picture, so that I could only use the firejets when going round in a circle!!!
Now with its own dedicated channel the jets should work whatever the tugs direction.
The other picture shows some of the cabling, including the historic Hunter speed controller, which still woks brilliantly with the new system, and drives the old Decaperm 12v motor.
Updates will arrive after completion of the upgrade and water trials.
