Mercruiser fuel consumption website. Anyone seen this before?

[poormonkey]

The other day i came across this, anyone seen this mercruiser fuel consumption website before? It has different size motors and shows fuel burn at different rpm's. Anyone think it's accurate? If someone has posted this before, sorry for a repost.

cool site. Seems a little high to me tho..

 

[MonacoMike]

New to me. The 7.4 seems close to what the Garmin fuel flow indicates.

Seems about right ("top up" empirical, not flow meters) for my 4.3ls, tho we're TKS/carb'd

 

[Darylle]

That is pretty cool and close to our fuel flow meter readings.

 

[PIRATES BOOTY]

Looks pretty darn close on mine.

The 496 numbers are way off. 3400 for us is 15-16 gph and 4000 pushes up to over 32 gph. That's per Smartcraft. Additionally, when I refill the tank it usually takes 10% more than Smartcraft predicts will be needed, suggesting the burn rate numbers shown are lower than true actual.

It seems too optimistic when I compare to my POed 320DA with 5.7MAGs. Their site is showing 12.5GPH at 4000RPMs, my actual numbers were 12.5-13GPH at 3600-3650RPMs.

Hey, www.botenkeuze.nl is my website (-; i'm from the Netherlands ...

Sometimes i have to choose between different boat tests data,
fuel consumptions date can be higher or lower on tests, i can only show one

On this moment i'm very busy making my new website, feel free for comment,
i can change fuel consumption data

I hope the English version is ready next week, its gonne be,

Under Construction only the US gallons version is almost ready,
and also contains twin engine and outboards

For me they are about 10% low. My Crusader 454/350's burn 14 gph per engine @3000 rpm (per Garmin GFS10 flowmeters) but that's pushing a heavy boat. If they were in a 34 ft EC the #'s would be close. When the 4 barrels open @3150 all bets are off. Good info and useful as a guideline. Just have adjustments based on heavy or light engine loads.

Hey, www.botenkeuze.nl is my website (-; i'm from the Netherlands ...

Sometimes i have to choose between different boat tests all over the world,
that show the same engine,
fuel consumptions can be higher or lower on tests, i can only show one

On this moment i'm very busy making my new website, feel free for comment,
i can change everything (-;

I hope the US/English version is ready next week, its gonne be,

Under Construction so dont click on the website this week!

Welcome aboard, Mart. Please let us know when the new site will be available.

I think it's pretty close to my real numbers. At 3500 rpms I burn right around 16-17 gph for both motors depending on conditions. The site stated 8.5gph at 3500.

It's spot on for Saint Max with a clean bottom, tuned props and the tab entensions.

Welcome aboard and thanks for the info.

 

[AKBASSKING]

Little off on mine, but I have 260hp Mercs. I burn about 14gph at 3250rpms per motor.

Is Ethanol used in Europe? Ethanol may account for some percentage of the additional fuel consumption that we see.

Added to my fuel consumption (hobby) website an option for boat owners with a Mercruiser engine, who can vote, more or less fuel consumption, many MerCruiser engines have no votes yet, so.... if you have a fuel flow meter......

Funny, the 8.1 (375 hp) is spot on according to what I see on my boat.

Same for me Scott.

Same for me Scott.

Thanks for voting on my website :thumbsup:


For MerCruiser owners who want to vote:
Votes are going to my email box, they are not directly on the website!

Unfortunately it is accurate for my boats..:smt089. .7 MPG for my 340 is about right... Makes me think about where I will be going... Maybe using the little boat more this summer...
