As you can see from my past postings, that I
literally build these motors and hope for the best! Mainly
because I know no better...<br>Nock on Wood, I have never
had a failure (or Fire) yet.<br><br>I am trying to
improve the motor that I want to build for my newest boat
(which is a 14' Long 50" wide aluminum jon boat). I want
to buy a Advanced<br>D.C. motor part #A89-4001. Its
a 36 to 72v motor and I will run it at 72V's. I am
going to use a Curtis 1209B-6402 controller rated at 48
to 72V's and a 400 amp limit.<br><br>In an effort to
improve performance over the used golf cart motors I have
used in the past. (36V models that I would push to
48V's) I was wondering if anyone could help me with
this? (Also see my posted illustration)<br><br>First
off...Is this an improvement? Or just another way to spend
money? :)<br>Should I look for a lower unit that uses
1.5 to 1 gear ratio or 2 to 1 ?<br>Any ideas on what
size prop to start with, and what I should look for
once I am on the water testing the motor?<br>Also I
see that alot of you are using gear reductions,
pullies,and belts,Would I benefit from this type setup on a
much smaller and lighter boat?<br>I don't know
anything about the "Ray electric Outboards" What do they
use?<br><br>I know there are alot of questions, and Im
certainly in the learning stage! So please bear with me! I
would greatly appreciate any help anyone can give
me!<br><br>Greatfully<br>Scott
