Got my new motor mounted 14 days ago. It Has now been running for 11 hours. I have lately run it at WOT several times for short moments. My boat is a Galeon Galia WA 660 produced in Polen. Total dry weight with motor is around 2500 lbs. The Motor is mounted on a CMC electrohydraulic powerlift and the motor is mounted with a 24" Raker prop. At WOT I reach almost 5500 rpms. trimmed out and lifted high. My GPS shows 61 mph. with a light load. At WOT the SystemCheck shows a fuel flow of 75 lph/19,8 gph. The local dealer told me before I ran the motor at WOT that the Motor has a consumption of 87 lph/23 gph at WOT. Why cant I reach this consumption? I use 3/8" fittings and tube from gaztank to motor. The external waterseperater/gazfilter is recomended for Mercruiser 4,3 220 hp. and other.<br />I did expect 65 mph. and with the missing 12 lph. I am wondering if it perform all 250 hp. I think 20 gph. is more like 225 hp.<br /><br />My local dealer has various explanations, my boat is very easy to push for the motor - the fuel consumption might show up later after more hours - The SystemCheck fuel flow sensor might be wrong. <br /><br />I dont feel comfortable with these explanations but the dealer tells me that he has checked with the danish importer.<br /><br />Can anyone give me a better explanation? What are the experiences about fuelflow with this motor or a 250 hp. E-TEC?<br /><br />Thanks in advance to anyone trying to help.<br /><br />Best regards<br /><br />Brian

Should be pretty easy to get an idea of the actual fuel consumption.Top her up take her for a run and top her up again.Should at least give a close estimate of gal. per hour.

Re: Fuel consumption at WOT. E-TEC 225HO

Lets see....youre running at less than 12% slip, faster than you hoped for, burning less fuel, and all this without dialing in the set up. <br /><br />So what youre saying is that the E-Tec is way better than you or your dealer hoped for. And now you want to know how to burn more fuel???<br /><br />Obviously the E-Tec engine management systems are working perfectly. You could use some more rpm. That will come with testing different props. While the 24 Raker is absolutely the best one in the line youll be looking for a prop that can handle a higher X dimension. With an HO you have one of the best stock gearcases in the industry. <br /><br />I'd suggest looking at something like a Turbo Lightning TXP with the 14 3/4" diameter. <br /><br />I cant wait to get my E-Tec. Thanks for the good reports!

Re: Fuel consumption at WOT. E-TEC 225HO

Topping up the gaztank won't give me the exact numbers of fuel consumption as I need in this case. I would have to top her up twice at WOT. I dont think it can be done at 60 mph.<br /><br />To Dhadley. First of all I dont get the speed that I expected. I mailed the manufactor of the boat and was told that they had tested the boat with a standard 225 hp. Yamaha V6 carburated motor small block. With 2 persons and low fuel they reached 60 mph. Thats why i ecpected 65 mph. with the E-TEC 225HO. <br />I have worked hard to reach the 61 mph with the powerlift and the trim and I only get this speed when I'm alone in the boat with low fuel.<br /><br />Obvious the goal is not to burn as much fuel as possible but to be sure that the motor perform as it should.<br /><br />I expected the fuel consumption to be close to the 87 lph. no matter if the WOT rpm's are 5300 or 5800. The recomended WOT rpm are between 4500 and 5800.<br /><br />I think the prop isn't all that bad. This autumn a friend of mine will make som changes of the hull bottom at the rear. The hull is a litle bended at the rear from the manufactor. This work as a kind of build in trim getting the boat fast in plane. But it also give me troubles at high speeds as the boat isn't responding well enough on trimming the motor out. My friend is a prof. fiberglass worker at X-yachts. He will grind of the bend and put on new gelcoat on the outside of the hull. Inside he will strenghten the hull with extra layers of fiberglass. I look forward to this and expect to get more rpm's and speed as a profit.<br /><br />I dont know about the gearcase as Dhadley mentioned. The E-TEC HO has a new gearcase not similar to the Ficht Ram HO models Lightning gearcase. It looks like the Lightning with the torpedo shape but it dosnt have the low water pickup in front. Still I can raise the motor untill the caviation plate is 5 inches ower the hull bottom keeping full waterpresure and without the temperature to go up at WOT.

Hi Xako,<br /><br />Not wishing to hijack this interesting thread, but I think some others beside myself are curious about this:<br />

Are you planning on fitting a pad? Or are you shaping a flat pad into the hull of your boat? What exactly are you doing here?<br /><br />The report on your new Etech sounds great. Give it a chance to run looser and I bet you'll be even more pleased with it.

Re: Fuel consumption at WOT. E-TEC 225HO

I still think youre doing pretty darn good. I wouldnt worry too much about the fuel consumption. It will come up as you get closer to your target rpm of 6000. With the different props youre going to try youll get more speed too. <br /><br />And depending on how many hours are on the motor, the r's may come up as it gets time on it.

I think he means he will remove the factory hook in the pad.

Re: Fuel consumption at WOT. E-TEC 225HO

Hi Stillfishing. <br /><br />You are very wellcome to join us. <br /><br />The hull allready has a pad. No its the bending or "hook" close to the transom that I wont to remove. The pad has allmost no bending but as you go to the sides the hull has about 1/4 inch "dropnose". This build in trim keeps the nose down at high speeds prevent the boat from getting the lift which is nesesary for realy high speeds.<br /><br />I wont make any experiments with props before the hull has been done. 6000 rpm!! I think that is 200 rpm. higher than allowed from factory. I am afraid it could give me som waranty problems.

Nope. Check the factory literature. The rev limiter is set higher than that.

From the operators guide I am told that<br /><br />Full throttle operating range is 4500 to 5800 rpm. for 200, 225 and 250 models.<br /><br />The rated power comes out at 5150 rpms all models.<br /><br />The 225HO are not mentioned anywhere in my operaters guide.

Yep, the E-Tec goes to 5800. I had the page open to the DI section and they go to 6000. Once yours gets broken in it'll gain some anyway.

Thanks for the replys<br /><br />I still hope to here from owners/users who has experiences with the fuel consumption for the E-TEC V6's<br /><br />Thanks in advance<br /><br />Brian

Re: Fuel consumption at WOT. E-TEC 225HO

I have now found the reason of the insufficient fuel consumption.<br /><br />A bumblebee hat found its way in to my fueltank where it got sucked up into the fuelline and was stocked in a 3/8" valve. Sitting in the valve it disturbed the fuelflow. Removing the bumblebee immediately gave me an ekstra 200 rpm's and the fuelconsumtion are now about 22 galons pr. hour. It allso gave a little more speed but only about 1 mph. Pictured: <br /> http://www.baadgalleri.dk/uploads_large/4730.jpg?30-10-2005 23:55:32<br /><br /><br />The motor is still doing great and now getting the declared fuel consumption I am convinced that it performs as it should. It's been running for 20 hours now. I have used 310 litres of fuel and 2 gallons of XD-100 oil. The oil consumtion should go down now after the break in period has finished.<br /><br />The season has ended and i am now ready to do the work on the hull bottom. <br /><br /> <br /><br />Best regards from <br /><br />Brian

Re: Fuel consumption at WOT. E-TEC 225HO

You know, reading this thread, I was going to spceulate excessive shear viscous forces from the hooked hull combined with possible turbulent non-laminar propulsive flow off the prop .. but "bumblebee" would have been my next guess.
