Last season fuel gauge for starboard engine was twitchy. This season, no reading at all. Anyone changed one out with ease or has some advice? Thanks.
 
It's a super-simple, straight forward swap out. Depending on the boat, getting to them can be a bit challenging, but it's all doable. First, double check it's the sender (most likely, though). Remove pink wire and with ignition on (don't need to start engine, though) gauge should show empty. Next, ground it - gauge should show full. You'll want to check your parts manual ahead of time to order the proper depth sender - or remove it and go to your local marine store and match it up - these are very common items.
 
Thanks guys, just saved me some change to hire the marine mechanic!
