The socket head bolt's threads are coated with a loc-tite like coating and also have new gaskets. I would always replace gaskets especially since they seal fuel. Don't want fuel leaking into the bilge. The bolts and gaskets are a cheap insurance policy.... -
That's the right part. You will also need a new gasket and 12 new screws. As for frequency, I changed mine when the pump went out and that was at 700 hours.Leave a comment:

Any thoughts on the voltage drop between the negative post of the battery and the ground stud of 1.4mV is anything to worry about?Leave a comment:

Your last post stated "Grade-8 bolt and nut with star washer and never look back". That's what I did - Grade 8 bolt, lock washer, flat washer. Are you suggesting the Grade 8 bolt needs to be a shouldered, double hex bolt?...Leave a comment:

Got everything back together. Chased the threads, cleaned out the hole, got a new longer M10-1.5 Grade 8 bolt. Reinstalled the grounds and made sure everything was tight. Measured the voltage from the ground terminals of both batteries to this common ground. I got 1.4mV of drop between the either battery...

This thread, and the overall price of new boats is why I can justify keeping and fixing my 2002, no screen X-30. I love that boat more and more everyday when I read posts like this. If I did get a newer (not new) boat, it would not have any (or minimal) screens....Leave a comment:

That's my thought too. Probably going with a non-stainless material....Leave a comment:

SS for a ground?...Leave a comment:

The safety lanyard pulls power from the fuel pump. That's it's main function.
You can jump two of the pins on the connector that the relay plugs into to see if you can get 12V on the stripped wire. Not sure which two pins to jump.Leave a comment:

What are these called? Nothing comes up on Amazon when searching for "threaded rod with hex bolt" or something similar. Do these bolts has a special name?...Leave a comment:

You will need to poke a flat bladed screwdriver between the relay and that grey piece that is holding it to the board. With the screw driver inserted, slide the entire relay and connected harness down and off the gray retaining clip. Then release the clip shown in your picture that holds the relay to...

The boat is winterized right now. I may have to de-winterized or wait until April of next year....Leave a comment:

So you're saying thread a M10-1.5 stud into the location, put the 4 ground terminals on the stud and torque it down with a nut. If so, I would also add a flat washer and lock washer between the nut and ground terminals....Leave a comment:

How would one measure for a voltage drop at the ground lug?...Leave a comment:

The relays should be the ones labeled 4, 5 and 6 (Starter, Ignition, Fuel Pump - not in that order). The labels 1, 2 & 3 are the connectors going to the ECU (looks to be a MEFI2)....Leave a comment:

The thread is metric, M10-1.5. My tap and die set does not have metric threads. Looks like I'll be getting another tap and die set.Leave a comment:

All 3 on my relays are the same part number. However, the only way to tell which one is the starter is to have your wiring diagram and know which color wires go to each relay. I can tell for you for a 2002 X-30 with the 8.1L engine, the starter relay has 4 wires - Yellow/Orange strip, Yellow/Black strip,...Leave a comment:

Main Ground - question
As some of you know, I've been chasing "issues" with my 2002 X-30 for over 2 years now. While it has pretty much always run during the last 2 years, it hasn't run great. My latest issue is a series of codes from the ECU (MEFI4). MAP Sensor Voltage Low (code 34) and Crank Signal Fault (code...

You should be able to measure 12V from the red wire (coming directly from the alternator) and ground. When the key is turned on (to the right), there should be 12V from the yellow/red stripped wire and ground. If you aren't getting 12V between the yellow/red stripped wire, your starter relay may be...Leave a comment:
