Water Temperature Sender 1/2" 14 NPT - Sierra
by Cliff from Layton, Utah on July 10, 2012
This sending unit for my 1978 OMC 800 reads high. It reads at 210 when its really 175. Is there a different sending unit for my boat? I just finished checking it this last weekend and was going to contact you. Please let me know which sending unit works with my boat. Thanks, Cliff 801 678 8240
