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

Problems with initial
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 Waters
