Hi
Vance,
I’ve always filled
the motors with light oil and forgot about them. I just drill/ tap the motor
housing for a pair of small barb fittings and connect them with a loop of
clear tubing (make sure you get tube that stays flexible in cold water). The
oil with travel through stranded wire so you’ll also have to strip the
insulation back on a small spot, solder a small area and then pot the wire
with a urethane or epoxy compound. As for the oil, WD-40 works great- It
displaces water and won’t attack electric insulation or rubber seals. There’s
always talk on the internet about fear of metal shavings getting in the oil
but as far as I can see you just get a little suspended carbon and it doesn’t
seem to have any effect on how the motors run.
Greg

Hey Greg,
The
K350 is pretty close to ready for sandblast and paint, then it's down to
wiring. Probably all summer to get it hung back together, what with all the
rebuilds, including the thrusters. I'm still hemming and hawing about the
Minn-Kota package. Carsten and Emile are working up some stuff on installing
spring loaded ceramic seals on trolling motors, which works well on the
Minn-Kotas, but I'm running out of time here and may just go ahead and whack
everything back together rather than reinvent the wheel. This one I've got has
the 3hp aft thruster, which is a pain as it is direct drive and runs a small
prop, but hey, it's already on the shelf, so why not use it? Then the second
boat will get the Minn-Kotas. That one is the 1000' hull with big
windows.

How is
your boat coming along?
Scott,
The plans specify all
dimensions and measurements for metal on the boat. Each sheet has a materials
list. Or at least every sheet I have ever seen. You shouldn't have to be
taking anything off the print with a ruler.

I am trying to get all of m y metal
ordered for the main part of the sub (k-350). I am having a real hard time
gauging the blueprints. I was wondering if anyone had a list of measurements.
I am going to order the main vessle and ribs, two battery pods, conning tower
and hatch, and VBT. I can't seem to get the plans to scale because they have
been saved in PDF and were compacted before they were saved and they
have no measurement scale except 1/4" equals 1' which doesn't help if the
files have been compacted. HELP?
Thanks,
Scott
