I can't attest to the speed but I can say that when I move the thruster handle in the slip, the boat almost jumps with the thruster movement! I have a SidePower 10hp 24v thruster.

"I'd have thought a thruster rated at (e.g.,) 100 lbs of thrust (or whatever) would but out 100-lbs of thrust no matter what the voltage."

Sorry, Chris, you are correct.

For 2 matched thrusters, the 24V unit has 2x the volts and 1/2x the amps, equals same power as 12V at 2x the amps. So for example, matched Vetus units 6012D/6024D) both are 4HP, 60KgF , but one is rated at 280A, the other 140A.

Same point though about the weak point being battery condition, cable etc given the high current draw, especially with 12V unit.

I had a Side Power thruster on my 30' Pilot and would bump it for a maximum of 10 seconds, never trip the thermo switch in 5 years of ownership, can't remember the specs but I had an 8" tunnel.

My same year and model boat as the PO's came to me with a Side Power SP-55 powered by two parallel AGM starter batteries, the only batteries in the boat at the time. Those two batteries, which are in the forward part of the engine compartment, are at least six years old and still powering the SP-55 with no problem at all. I typically use it in several 5-10 second bursts, and I can run it for longer shots if I feel the need with no ill effects. I'd be looking at the battery condition, the condition of the connections, and possibly renewing the thruster's motor brushes.
