looking at a 42 tiger with 540 bulldogs imco extention boxes how fast do you think it runs..

straight bottom 73 to 76 mph stepped 80 to 83 mph

this one has a straight bottom . how big is the fuel cell

it should be 280 gallons. twin 140 tanks one per engine

thanks i hope i get it sent in apps and contract on it yesterday.

What Is The Range On 280 Gallons You Think At Cruise Speed 3800 Rpms

thats a good question. i would say 3800 to 4000 is the sweet spot. you should cruise at 55 to 60 mph and should get 3/4 a mile per gallon to be safe. maybe more it is hard to tell being that it is a carb setup with a non step bottom

Close to a mile to the gallon.

Also, speeds will be more like 70-72 mph with that setup

the seller told me at 38-4000 it ran about 55-58 mph
hell that cool with me.. 210-280 to a full tank thats get me places..

Yeah - I believe the lower 70's....but watch those drives...... straight bottom Tiger = bravo killer
