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, JustinAttachment 402871

Justin-

Boat looks great!!! About time you posts some pics!!! You also may want to post this in General Discussion (you may get more info about your 500's)

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?

NICE BOAT. Switch might be the power point. Higher temp could be weak water pump impeller.

Im with Bobby on this one ,change the impellor

Happy turkey day Bdarcher and check your email :lolhit::party-smiley-004:

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.

I see RunninHOtRacing is back on the board. Sending private emails spreading his wisdom.

What EMAIL

Its about time Runnin comes back. This place is kinda boring lately. He livined OSO up. Sorry for hijacking JUS490

Runnin hot is hilarious. I ll post some pics of next weeks Black Thunder/Ateco engine pull. Sorry to stir the pot. Brad PM me if you can help mediate this problem.

JUS490. sorry about being groggy on the phone. Just woke up. I spoke to Bob, if you have a fax, we can send you a schematic or call me and i can tell you what to tie in to.

Bobby, what is the plan for your motors this winter. Keep us informed of what mods you do. Best of luck and good hunting

I still havent pulled motors. Ill probley tear them down and have BB&T do machine work and build myself. Im still not sure about mods any suggestions , but would still like to have alum heads. Im a littled worried about XRs.
Thanks Bobby

Lets see those pics of the pull, and get Runnin back.:drink:
