Well, it has been in the 30's and high 20's this week here in Chicagoland. Thinking of running the electric boat one last time this weekend. I would like to test it out(due to a mishap last weekend) to make sure everything works properly. So if it does not I have all winter to fix it.

My question is water temp is probably in the 40's if not lower, and was wondering if I need to take any special precautiouns for running in much colder water than my boat is use to?

From my point of view (I get your weather about 5 hours later), nothing should change. Your motor should run cooler (From the air and also if you have water cooling).

Expect your batteries to have a little less punch and a little less runtime. For the same reason, your servo(s) may respond a smidge slower...so keep that in mind.

Other than that, watch out for icebergs! I will be out on Sunday for my first (After several upgrades) run!

I would say no . electric motors like to run better when its cool but batteries however lose there punch in cool weather .

Harvick - what boat are you talking about and what town are you actually in ? where do you usually boat at?

just remember plastics become brittle when frozen and brake so will other materials,we used to snap brake cables on our bmx bikes in the winter and its not even that cold here,i live in baltimore MD

A graupner cat with a 700. I live about 15 miles southwest of you in Cville! Just running in ponds around my subdivision. There is also a dedicated boat pond on Rt. 83 and North Ave in Elmhurst. Only go there in the summer though.
