New to here and outboards. Just purchased a 1991 Hydrasport 1850 with a 1998 Yamaha 150. The engine temp gauge does not work. It has hydrasport gauges not yamaha. I think I found the temp sending unit on the engine, but the connector looks like it is sealed and cannot be removed from the sender? The wire go's down the center of the sender and sealed. Also the water pressure and trim poition does not work. Do not know what the water pressure gauge is for. Any help?
Thanks
