I have a AQ240 engine with a 280 drive. I need to replace a tilt relay. I have two relays, one is a five terminal and one is a four terminal. I need to replace the four terminal relay. I can find many five terminal replacements online but am having no luck finding the four terminal one. I have searched and contacted tech support at various vendors but am still having no luck. I think I have an early 280 drive unit on my boat. Relay is a 12V 30 amp.
