ok i need so questions answered before buying one of these things cause i dont want to light my boat on fire  . 

i have a 2004 trackerpt175 and with the front panel removed the TM only has two wires running to the plug (however they are pretty heavy gauge wires).  my question is if its a 12/24 system would there be 4 wires?  if not can i run a 24v system on the two wires alone without frying fuses?  my boats manual is pretty vague so i was hoping someone here is a wiring guru.  thanks for any info at all.

It depends on how you want to wire it up.  There are a couple of different ways depending on the type of mtor your have.  Some with the 12/24 switich would need both sets of wires.  Just 24 can use two or one set depending on the type of plug.  You probably will just need to run a jump wire from the pos. of one to the neg. of the other and then connect to two remaining to the existing wires.  They should be at least 8 guage.  Also make sure you have the circuit breaker or fuse in the circuit.
