Have just fitted a new trim gauge and sender unit but when the engine is down the gauge reads that it is up and vice versa any clues as to what the problem might be Thanks Richie

Adjust the sender position on the saddle.

Have tried but can't get it to fit into slot or mounting screws

If its a starboard sender you need then I have one, new in packet, Part No. 821400A2, RRP: £96.00. I bought it by mistake as its not compatible with smartcraft. £45.00 if you want it.

Will fit, 90hp fourstroke, 90 Optimax (none smartcraft) and 90hp 3 cylinder with single ram trim; 9502500 / 0A966142 and up.
