'84 140hp

[jacknz1]

Hi I'm new here, I have just bought a boat that has a 140 on it, the trim guage isn't working, where do I start looking to fix it?

Motor has 450hrs of fresh water only use, how many hours can these motors last with regular servicing etc?

Thanks

Check for voltage and ground at gauge, test trim sender on engine.
