Trying to get a solid read on the weight of a boat I’m considering purchasing. It is an 88 272 SR1 twin 350/Alpha setup. Trailer is a double axle steel Vanguard unit. Anyone have any idea what it would weigh, with gear, fuel etc etc?

My SUV(2010 Infiniti QX56) is rated for 8900 lbs. Power wise it is making about 50-60hp over stock so close to 400.

TIA

Hi,

that would be a very nice boat.

weight of boat with fuel is 6700 pounds with fuel. I’d add about 1200 or so for trailer. So you are just under 8000 pounds. Then I’d add 500 ish for any gear, coolers, etc you may load in boat.

attached is link to the brochure.

good luck.

I had a 242sr1 that I trailered from Central NY to Cincinnati and now I have a 311 SR1.

Hope this helps,
Chris

Formula lists it as 5750 dry weight. 133 gallon fuel tank. Figure 1/3 of a tank your adding ~270 lbs. 500 of gear and junk. Plus the 1200-1500 for the trailer...

I'd say 7800-8000 is a pretty good number. If your max towing capacity is 8900 your at a out 90% capacity. I usually like to keep it not much more than 2/3 capacity so you aren't over working the rig, brakes etc. Depends a lot on how much towing you are looking at doing.

They don’t specify which engine and drive combo that is for though. SB or BB? I suppose Icould call Formula. I would rarely tow with that much fuel in it also.

the weight difference from SBC to BBC is very small in comparison to what you already know.

bbc are roughly 660 pounds

sbc roughly 550 pounds

bravo 1 roughly 135 pounds

alpha 1 around 95 pounds

so your total weight is give or take 150ish pounds.

You may very well have the ability to tow the vessel.

The area of concern is stabiliryand safety while trailing down hills, and stopping. The shorter wheelbase when you have all that weight behind you will test your vehicle. Braking is another. Changing lanes and swerving are things to think about when trailering such a vessel.

it’s doable. I had a 1/2 ton Chevy short wheelbase that towed my 242 around. Did great around town to local lake. Stopping was at times slow, but manageable in a 20 minute drive around town.

then I moved to Ohio and traveled some longer roads, hills and traffic. The boat would push down a hill and the truck would become more unstable. Moving quicker and changing lanes and then having to hit brakes taxes the vehicle more so than local travel around town.

just things to think about.

Known scale weights of a 272 with low fuel and otherwise empty come in at 9k lbs on a steel trailer. Aluminum may save a thousand pounds or so. Add gear and fuel. I wouldn't tow it with less than a 3/4 ton unless you're going very short distances.

Remember, it's not the power of the tow vehicle that's important; it's the ability to safely control and stop the entire rig. I don't think your Infinity is up to the task honestly.
