Subject: [PSUBS-MAILIST] Side Thruster
Options
Greetings James,
I'm also planning
on installing small mostly off the shelf thrusters on the sides of my K boat
to reduce drag and simplify things. I've been planning on using 36 volt
Minn Kota 101 saltwater thrusters, like Frank, and I believe Vance are using
and oil compensate them. Last I checked those thruster were running $250
each with the speed controllers going for $150 each.
I'll
have to check my notes, but I believe Karl Stanley is using 6 of the 36 volt
Minn Kota saltwater thruster that he has oil compensated, and has used down to
2500 fsw. Two for vertical thrust and four in the stern. Are you
expecting to go that deep James. ;}
I like the idea of using the
existing flexible shafts on some motors that Alec mentioned. I expected that I
would clamp mine on in a similar manor as Frank has done, since I'm not sure
of the long term saltwater durability of my favorite brand of duck
tape.
I see the need to beef up the side thru hulls, and was planning
on looking closely at how Dan beefed his up. With the new tangle guard
configuration I'm planning, I don't expect the thrusters will sustain any real
damage unless the Euronaut or the like plays to rough with my
sub.
Regards,
Szybowski

Oil, ambient air pressure regulator?
