Default HP 500 EFI vs HP500 carb

Hey, have any of you guys ran a HP 500 carb vs a HP 500 EFI in the same hull? Was there any fuel mileage benefit to the EFI? I have heard the carb motor does pretty well as far as mileage.

I am going to be looking for a boat fairly soon and I will be looking for a HP 500 or 525 EFI. By then gas will be 5 bucks a gallon and I will be buying a boat no matter what, I just was wondering if there is a noticeable difference

Rex,
I can't help you with an answer but maybe a bump to the top would bring this back out in front of the membership here.
My guess would be that the EFI would make better power and use less fuel.

See ya,
Kelly

Just being to the point, if you are worried about fuel mileage between the carb and efi engines you have no business buying a boat right now.
The gas is the cheapest part of owning a powerboat. I would pay $10 a gallon if I knew for sure that nothing else would break all season.

Engine replacement $6500-$12000
Drive replacement $3000-$5000

Gas is small in the big picture.
Just my opinion.

The EFI engine will be a little better on fuel. Probably only about 5-7% better.

I knew someone would give this answer. If you dont have an answer for the question, I dont want your opinion in my thread. Thanks.

I have owned boats before and understand the economics just fine. I am curious if I should prefer one over the other

I bought a 95 29 with twin 500 carbs and later changed for 500 EFI's. I like the EFI's much better. Fuel effeciency, I really could not tell that much difference, but after sitting for a week or two, I would never go back to carbs. EFI's started so much better and not as much fuel smell when backing up and not as much black smutt on the rear of the boat.

Thanks Kelly and Roger.

Since a 29 Fountain is on my short list I really appreciate Roger's insight being the Fountain man that he is

If you have owned boats before why ask a question that you already know the answer to???

Beginners............Gotta love them
