ORIGINAL: JMES241
Its a hobby boat, quite big. Its hand made so im not sure difference that will make. Its a 5 band system and is a normal monohull boat. Ive got the propellar workig which wasnt working at first. Also, there is a tube that the propellar squirts water into, sends it through a tube round the boat and sprayes it out the back. I was wondering if that would do anything. Please help. It will be much appreciated.
yes you need it, the water goes to your engine head too cool it.
The other way you can do without that tube is to replace the rudder blade with a one that has the water pick up built in.
