GT40 probs

Hey Eddie,
I am still trying to figure that one out. I was pretty religious about using the non ethanol from the Citgo next to the Catholic church on 17, but the team was running the boat so much, I started using the ethanol blend from the Racetrack so as not to bankrupt the team and on the notion that ethanol gas would not be a problem if it was consumed quickly. So that is part of the mystery. I am also wondering if the rain water was able to make its way past the threads of the screw cap if it was not cinched down tight. We got a LOT of rain for the 2 days I was gone, and apparently my cover is not exactly rain proof. I am thinking that the cover, being fabric, really held the water that was not running off, and that the cap touched the fabric doing the classic "dont touch the inside of the tent when its raining" thing. I am guessing it would not take much and at the time it only had about 8 gallons in it anyway. I have just never seen such a uniform, cloudy, Gatorade yellow mixture before.
Tom

The only way that it could possibly be the ethanol is if it was a bad batch from the station. I run ethanol from Race Trac or 7-11 and have had no problems at all. But I also run Stabil religiously too. I didn't even realize you could get non-ethanol around here but I'm sure you pay for it.
I have to think you got water in the tank. That would certainly explain the yellow Gatorade appearance.

I would love that to be the problem because then I would have an answer!

I haven't had time to read all these posts, but I did get that the bilge flooded and now the engine runs badly.
1. Has anyone looked at the engine oil to see if it looks like a dirty milkshake? Water WILL get in through the rear main seal if the bellhousing floods.

2. Take an air hose a blow out the "gate" in the distributor that the tabs on the Hall Effect wheel go through. There is a magnet in there, and if a little piece of rust or magnetic metal gets in there, it confuses the heck out of the computer.

Scamp On

I was 100% on the ski nautique, but I fell off the wagon on the new boat because it burns so much more (310hp vs 240hp) I was under the impression that a 240 HP 351 and GT-40 351 burned about the same amount of gas when used at skiing speeds.

I have not actually done the math yet, but it sure feels more painful!

Geez Tom,
How about fessin' up and just admitting that you're using it more than the old boat!!!!!!!!! That's why you're putting more gas in it.

I agree. That is a lot more boat than the 89 SN. I noticed the most increase in fuel use when Eddie was behind the boat, because I think he is made of iron.

Is this your Pro-Air? No wonder it's using so much fuel

As much as it pains me I totally agree with Timmy, was pleasantly surprised by the efficiency gains that came with my first EFI boat......despite it being a Ford

The impression I've gotten from the sports and pro airs that I've driven is that the extra length was added mostly to the nose (for bow seating). All seemed incrementally more lethargic than a comparable SN. Perhaps the longer nose is giving you the impression that they get more hull out of the water? Perhaps they do, but I think they have every bit as much (probably more) hull in the water.

2001's ride significantly more bow high than a NWZ or later SN. Compare these 2 pictures and note the attitude. Where the spray is breaking is a good clue as to how "planted" the boat runs.

not to threadjack, although I really don't care too much...Tom, that was at TRBenj's CT mini 2 years ago...if you want to have a good time, head that way when it comes together in august. it is a family friendly affair as HW and I do the majority of the heavy drinking, but we ski all weekend and your boys would learn a ton from the calibur of skiers that are there. if you don't have a tent I'll bring one for you.

Tim, good comparison with the brochure pics. On the '87 2001 I like using the picture on the right, the one on the left has 300 lbs. of passengers in the back seat so not the best comparison. No question I can see the bow firmly planted in the '92.

Not sure when I can do it, but I have a neighbor with a '98 Ski, I'll see if I can get him to make a few passes at ski speed and a bit faster while I video, then do the same with my boat. Would make for a good comparison of the 19 1/2' and 21' boats from the same year. I'm sure you are right, I'm just seeing the longer nose and assuming it's less wetted surface, and likely the opposite.

I agree should be a calendar pic!

Joe looks like he's ready to bail out quick if a rogue wave goes over the gunwale. that's probably the most weight I ever had in it, best guess is around 3000 lbs, and let me tell you it was a pig to drive, but it did the job. I do love that pic though.

Could probably surf the bow wave!
