<table cellspacing="0" cellpadding="0" border="0"><tbody><tr><td colspan="1" rowspan="1" valign="top">Hi people,<br clear="none">I've spent several hours today looking at brushless thrusters & wonder if anyone else has looked at them or got any ideas. There is the Indonesian thruster I posted a few weeks back at US 2,200. There is also the Haswing Protruar 2hp that Emile has; however they state that it's for fresh water only, & I think Emile said it was a bit noisy.<br clear="none">The inrunner motors that have the winding on the outside, seem a good option as they cool through convection to the can. They also need higher revs for torque & require a planetary gear box or similar. ( which a lot have built in)<br clear="none"> I was looking at the option of making my own thruster, however the motor would require a thrust bearing & I don't<br clear="none">know of any that would have one other than
maybe a high powered battery operated drill.<br clear="none">Any thoughts, suggestions thanks.<br clear="none">Alan<br clear="none"><br clear="none">Sent from my
