Considering GO-480

Postby Cody25911 » Sun Aug 23, 2015 6:56 pm

Were should I look for one and were can I find parts? I know that is easier to type then do. I have looked at all the options and not many people who own these dis like them. So I figured I might try this route.

I have a fresh built GO480 for sale. Swings a 80in prop and just ran 74mi yesterday and burned 18gal. Absolutely love this motor but built it to sell. Call me at 239-253-4909. My name is Eric. I would be glad to take you for a ride to show you what these motors are all about. I attached a pic

Thanks Gary. I like this motor so much it's definitely crossed my mind to sell my GSO boat and keep this one but I'd lose way too much money on my big boat for it to be feasable. This boat burns almost half the fuel of my big boat. I put your adjustable pushrods in it and it sure is quiet and smooth. With the prop technology today I know these motors can be the next big thing. Swing a huge prop and burn as much or less fuel than a 540. It's been proven and this is a high compression motor to boot. 8.7/1 Ross pistons. So far burns 4-4.5gal per hour and averages 4mpg

That's great mileage. But by the way farmboy talked yalls gso boats get great mileage. Or does his get way better than yours?

My GSO burns 6-8gal per hr and averages 2.25-2.5 mi per gallon with the R. Used to get better with the Saber. About 1gph better across the board

Thanks man it's worth all the hard work I put in it to see it pull the numbers that I was shooting for. It is 300hp and ratio is a 77:120 which comes out to roughly 1.56 rounded up. Same as all geared lycoming aircraft.

Tony the best I've gotten was 5 gallons per hour even. That was riding by myself in Kissimmee... With the wife & kid and loaded with stuff I'm pretty much 7-7 1/2 gallons per hour. Still not bad for a gas guzzler motor..My boat having a wider bottom than Eric's seems to help a little. I will say when I first got this boat I was 10-12 per hour before we made some adjustments. We have talked to others at Kissimmee that said they burn 15 per hour with a gso.

Depends entirely on set up. The last GSO480 I tuned (Southernrican) was a step hull and he would burn 10gal less in a day than us on the bigger boats.

Tony what's does that LS motor burn per hour average ? I rode next to Paul Tillman and I burnt gallon for gallon as he did. I know his isn't a LS and isn't injected but I'd say it isn't bad a fuel tho. My hull is the same hull as his and both have poly.

I'm fine with my old supercharged dinosaur motor. It gets me from point A to point B so I'm happy. Burning more fuel than others don't bother me at all...

I'll have to check hours to gallons. But I know the last time we rode we went 71 miles on 16 gallons and that was a mix of dry and water running. 3 people in the boat with all our stuff. Memorial weekend we rode and made all the usual stops from polluted waters all the way to cypress and back to camp mack and only burnt 10 gallons eachday

I will say this Kevin's 480 boat doesn't burn any more than a 540 and the same comparable boat. A few times I've been with him riding the lake and burnt a little less. 5 to 6 gph is probably what the average 540 boat burns. I'd be willing to bet there isn't anyone else with a 480 getting those fuel numbers he is.id really like to see his boat with slick bottom and a longer prop. I bet it would be better then.

Tony what would your 540 boat burn in a days ride in Kissimmee? Making the whole loop?

Slick bottom alone would make a big difference...

I had no problems with my GSO once eric tuned it. It was on a fiberglass decked over step with slick bottom and I would cruise at a lot lower rpm then the larger boats and have a faster crusing speed but once eric.dialed her in I was burning 4-5 gallons per tach hour and that's including the occasional flooring it and feeling that whip lash for that instant chubby lol

My gso was turning 3850 on trailer around 3900 on water. So the prop was seeing about 2500 or so.
