This sender was an exact duplicate for my 454 marine power engine and matched the factory gauge on my Carlcraft houseboat.

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

Q:
Will this sensor work on the 3.0?
A:
You need to know the thread size of the sender you have to determine which sender will work. This one has a 3/8" thread size.


Q:
My sender has a 5/8 diameter on threaded side to manifold and 1/8 " Threaded side to where wire connects. Will this fit? Also, this is for a 350 small block Merc Cruiser?
A:
This is for a dual temperature station. It has 1/2"-14 NPT. 18-5896 is for a single station and has the 1/2" thread.
