Wiring Help 12 v system

[baironhorse]

Hey All

 

Alot of you dudes helped my big time in the past and you know who you are...I just want to say thanks again!..I hooked up a MG 36lb trust Bow Mount...I ran marine grade 4 awg wire all soldered in place and solid...If I want to upgade to more power no need to re run wire.....Now to finally complete my set up I was told to run 40 amp breaker inside battery box cover...This 4guage wire is not easy to bend and I split my $10 NAPA breaker in half once compressing lid .... Now I found the specs on my unit , the attached Motor Guide diagarm shows 50 amp breaker used ( i have attached link to specs for you to check out- file to big to upload)...My questions are as follows:

 

1. 40amp (suggested by masses) or 50 amp (specs) for 12v 36 lb thrust - wire run is about 23 feet

2. How the hell do you guys have enough room to install breaker inside battery box ( i have a 27 class Seasence Box) and make it all fit when closing lide and straping it down?...

 

My boat is really tight for space and want to keep breader dry and best place for this is in box!!

 

IF you have pics that would be much appreciated!!!!

How, real easy, use the shortest piece of 4ga wire with appropriate ring terminals to locate the circuit breaker right on top of the battery next to the positive terminal. The circuit breaker is only 1 inch long x 3/4 wide. http://www.princessauto.com/truck/truck-accessories/truck-electrical/8198798-50a-6-24v-stud-type-circuit-breakers
