I am running a new electrical line for my 24 volt trolling motor. In my owners manual it says to use a 50 amp circuit breaker. Just wondering if you absolutely have to have a breaker and if so do I need to mount it somewhere in the boat. My mechanic told me to use a breaker that costs 60 dollars. I think that is really expensive, It is a blue sea 50 amp part number 661-7100. The one that Motor guide recommends is only 9 dollars here is the link to that one. http://www.google.com/products/catalog?hl=en&xhr=t&q=motorguide+circuit+breaker&cp=28&qe=bW90b3JndWlkZSBjaXJjdWl0IGJyZWFrZXIgbQ&qesig=nDlNg2zGu635iNDAJkQbKw&pkc=AFgZ2tkLqDHycewOCZWULKMQ56Na61Y2yICMktfCkSz3qLp74cQdl6ljjZ49_scg0Rc7KxV7yq9ZYtsl4zT5KR8TCnqa4dOOag&pq=motorguide+circuit+breaker&bav=on.2,or.r_gc.r_pw.&biw=1366&bih=664&um=1&ie=UTF-8&tbm=shop&cid=6648815746107116108&sa=X&ei=MvMlTreQKuK1sQLdl93dCw&sqi=2&ved=0CGQQ8wIwAw

Here is the link to the Blue sea one. http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?productId=726541&catalogId=10001&langId=-1&storeId=11151&storeNum=10109&subdeptNum=10598&classNum=11287

Which one should I use.

Thanks,

Jenga, you are comparing apples and oranges The cheaper item is a fuse. The other is a circuit breaker. Both work equally as well. The difference is that the circuit breaker is more convenient to use because if it pops all you have to do is push a button to reset it. The fuse needs to be replaced if it blows, so you need to carry a spare or two and be prepared to break out a screw driver to replace the fuse. On my boat I use a fuse. IMO circuit breakers are a waste of money. That said, if you are a tournament fisherman and time is of the essence, then the circuit breaker would best suit you.

Whether or not you use either one is up to you, but you will void the warranty on your TM if you do not. BTW, mount it as close to the battery as possible. This will help protect the wiring going to the TM.

Thanks for the reply. I am not a tournament angler, maybe one day but it wont be with this boat. So I will just go with the cheaper one.

Thanks,

Jenga

I was in walmart the other day and noticed in sporting goods that they were carrying a 50 amp circuit breaker. The price was under $10. You might want to check your local walmart.
