Cat 3209TA Fuel Burn?

Cat 3208TA Fuel Burn?

Hello. Anyone know what the fuel burn rates are for Cat 3208's?

Welcome aboard!
CAT publishes its fuel use curves. Question is what version and year of 3208? Makes a big difference. There are 375 and 435 hp versions of the TA.

OK so on Boatdiesel.com there is a datasheet for the 1992 3208TAs. There are 2 versions. Remember these are numbers taken in a lab with the engine on a dyno using a generic propeller profile. They will be +/- 10% ballpark guesses PER ENGINE for estimating whatever boat that you have:


435HP
2000 rpm - 9.4 GPM
2400 rpm - 14.5 GPM
2800 rpm - 23.4 GPM


375HP
2000 rpm - 6.5 GPM
2400 rpm - 12.0 GPM
2800 rpm -21.0 GPM

Welcome aboard. If you are buying a boat with those engines get a good Cat mechanic to do an engine survey. The 3208 NAs will run almost forever. But with the higher HP ratings there can be problems so get them checked carefully. Good luck.

I know exactly what my fuel burn rate is for a pair of 375hp 3208T’s. How this data applies to any other boat I haven’t a clue. I can tell you my burn rate is different from what Cat publishes which is different from the number the CoastGuard published on one of their boats with a Cat 3208.

What is the application?

Hello. Anyone know what the fuel burn rates are for Cat 3208's?

As mentioned previously, depends on how you intend on running them, but seeing as this is a trawler forum, we might expect around 8 knots.
For twins, around 20 litres per hour or 5.4 US gallons at 1500 rpm.
Above that, I can’t advise.

My brother has the 375 HP version and he gets 1 gallon per hour at 10 knots in his 48 Offshore.

My Californian 55 at 64,000 lbs get 1 gallon per mile at 10 knots with the 425 HP 3208s. I'm usually at 1750 RPMS depending on bottom condition. I average 7.88 gallons per motor run hours which of course include putting out of the marina and some idling in the slip although I do almost 0 of that. This of course includes running both engines since it is a twin. I had a hard time believing the 7.88 average but I have kept records over several hundred miles and these numbers are always confirmed for my boat.

I’m guessing a typo. No way your brother 1 gallon per hour at 10 knots.

1 gallon per nautical mile at 1750 RPMs sounds very common for 3208’s for boats in the 50 to 60’ range. Speed will probably be between 9 & 10 kts. Every boat will be a little different.

Currents, waves and wind will also influence this number.

You are correct. Typo that I have made over and over. 1 gallon per mile at 10 knots. Same as me.
