Optimal running temp for 500 efi
Finally got some time to toy with the new BT and have a couple of questions? number one is what temp is right for a 500efi I took it out and ran it and one motor was running around 180 and one was running around 150 so I took the thermostat out of the hotter motor and it is a 140. Im guessing it is just shot from sitting but am curious if that is the proper stat. number two is there are three acc. switches on the dash no. 1 does the silent choice but I cant seem to figure out what the other two are for. Has anyone ever tried to get a wiring diagram from BT. any info would be greatly appreciated, thanks, Justin

Nice ride. The three switches on the dash control silent choice, compass on/off and the third on my dash is a dummy. As far as temps go, mine run at 150 all day. Never higher or lower. Bobs in and out of the factory right now but I ll be up to see him next week. What diagram do you need?

thanks for the replies. The first thing I did when we picked boat up was change the impellers and the motor that runs hotter did have a very chewed impeller so I am wondering if some of the rubber is stuck somewhere but on all the other boats I have dealt with the first place it gets stuck is the thermostat housing but when I took that apart I found nothing I am going to check the lower hoses but I need a smaller guy to get down there as I dont quite fit. as far as a wiring diagram I am looking for a diagram of the gauges/ switches because I have some lights and thing that I would like to wire in.
