What is this wire 1998 Prostar 190

I purchased my 1998 Prostar 190 a couple of weeks ago with 314 hours and in meticulous condition. I had it out for the first time this weekend and although she ran great have a couple of concerns I want to get your feedback on. The first thing I noticed was that she seemed to guzzle gas. My girlfriend and I took 5 or 6 trips around 10 miles up river and then floating back. I will admit I wasn't babying it the majority of the time I would say full throttle a quarter of the time and half to three quarters the rest. By the end of the day we were into the quarter area on the gauge and it did cut out going back to the dock. Is this normal or is there something I should look at fixing to improve the gas consumption besides the obvious of backing off the throttle.
The second thing I noticed is this wire on the left side of the engine (LS1) below the manifold that looks like it should connect to something, but I have no idea what. It is close to the starter, yellowish in color and has round end on it.

Thanks for your input and sharing your knowledge. I'm sure there will be more questions to come.

Mike

Nice purchase. The 98 is a beautiful boat. Gas consumption seems normal for what you described. Motor is an LT-1 and the wire is the exciter wire that should attach to you alternator I believe. Cutout is most likely too low on fuel and/or dirty inlet screen on fuel pump.

Nice looking boat!!! Not sure in the wire, hopefully mgs nailed it for you. Yes, that fuel consumption is normal. I'd say very good, 50-60 miles, 3/4- full throttle is actually great. At half throttle, 25-30 mph, cruising probably wouldn't have even burnt a half tank.

MGS - don't mean to show my ignorance here, but...
Exciter wire? I don't know what that is but sounds like it should be hooked up. It looks like it is designed to slip over something else (female connector) - any idea where on the alternator? It doesn't have very much play and has some corrosion making me believe it hasn't been hooked up for awhile. The closest thing to it is what I believe to be the starter (but I may be wrong on that) and I don't see any where to connect it there.
Thanks for your help.

If it does not have much play...it will not reach alt. Not near my boat so I am limited. There should be 2 wires on stock alt...if they are there, need to look somewhere else obviously. I'm thinking.

Leave the wire alone. Not an exciter wire. I'm not sure what it does either and I have the same on my boat. If the alternator is charging, then all is hooked up correctly.

I would assume it is for another "option" or accessory. We can start to trace it out or get a wiring diagram but for now as long as all the functions work (blower, alt, gauges, etc..) leave it alone.

Also forgot to say nice boat! I'm tempted to pull the flag decals off mine and add stars, but wife like it the way it is.

Yep everything works and the wire is slightly corroded - looks like it hasn't been hooked up to anything for awhile if ever. So if it ain't broke, I won't try to fix it. Thanks for the reply.

I have a set of the factory flag decals that came with it and I have been thinking about putting them on but don't want to cover up the blue metal flake - it looks way cool

Add stars to the side and make it look like a 98 S&S! Stars are easy to remove later on also.
