Author Topic:   1991 Outrage 19 Hull Weight

will posted 02-11-2011 01:21 PM ET (US)
I have a 1991 Outrage 19 with a new Yamaha F150. In the reference section, the [weight of the hull of a] 1980 to 1991 Outrage 18 is listed at 1,250-lbs. The 1992 Outrage 19 II is listed at 1,900-lbs. My boat looks almost exaclty like the 1980 to 1990 models with the exception of a taller console, taller seat and lack of wood. I want to believe that my hull weighs 1,250-lbs, but I would like to know for sure. Thank you in advance for your help. --Will

Your boat [hull] weighs approximately 1,250 lbs, dry.

If you want to know for sure, you'll need to go here:

For about $10, you will now for sure.

*know*

Peter, how can you say with precision? Do you know this boat? We haven't seen photos.

Depending on where you live, you can take it to a dump or truck stop to use their scale and weight your boat, Just make a list of everything (engine, fuel, equipment, battery etc.) on your boat; do the math. The weight of the trailer [comes] from the manufacturer or sometimes it [is] on the registration. Good luck

Dave -- I think, but perhaps I'm wrong about this, it is pretty obvious that if one wants to know what their rig weighs with a high degree of precision that they should weigh it. I read Will's question as looking more for a quick confirmation that his model, which is a little different looking than the 1981 to 1990 models because of the taller console, is the 1,250-lbs-model not the 1,900-lbs model. Based on his description, it appears to be the 1,250 lb model that does not have the third liner.

Unfortunately, I do not have a trailer to use to get the boat to a scale. I am familiar with the 1992 Outrage II and it looks very different from my boat. While my boat is a "19" it looks very, very similar to the earlier 18 Outrage models. I have always felt like my boat was a "tweener" as Whaler transitioned to the new-look hull. For trailering purposes, I am adding 475-lbs for the motor, 420-lbs for the full tank of fuel. and 300-lbs for batteries and gear. Once I know the hull weight, I will either need a 2,400lb or a 3,100lb trailer.

Will--I had the same boat. The weight of the hull is the same as the earlier models. They just labeled it a "19" and gave it a different console. The 19 II has a completely different interior which is the reason for the increase in weight.
I would go with the 3,100-lbs trailer even though you have the lighter hull.

Hi, I have the 1990 19-foot with the tall console, and, yes, the trailer you need is the 3,100-lbs-capacity one with bunks. The hull is 1,250-lbs with nothing else added, that is, ]engine], battery, and stuff. etc.

My 1987 Outrage 18 weighs 2,540-lbs. That is with 1/2-FULL tank of fuel, a back seat, 1987 150 Johnson, and miscellaneous stuff. No trailer. Weighed on a cherry factory scale.

You need to go for the heavier (aluminum or galvanized only) trailer--period. When you purchase your new trailer cover and spray all the nuts, bolts, springs, and axles with a coat of LPS-3, which will protect the parts from rust, and, if you ever need to take it apart, you will not have to cut them to get them undone. Trust me on this one. Good luck

A trailer for a 18-foot Boston Whaler boat is typically a single-axle trailer. If we use Con's boat weight as a sample, we have a load of about 2,500-lbs. The common trailer axle has a rating of 3,500-lbs. This gives a margin of about 1,000-lbs, and from this we have to subtract the trailer weight. I suspect that a typical steel boat trailer for an 18-footer will weigh at least 500-lbs. So we can look at the total weight of the boat, motor, gear, and trailer to be at least 3,000-lbs. This weight is to be carried on an axle rated for 3,500-lbs. This implies a margin of only 500-lbs, which seems rather small. However, we must subtract the tongue weight.
If a trailer and its load has a total weight of 3,000-lbs, we would expect at least five percent to be carried by the tongue. This means the tongue weight would be 150-lbs. The weight carried by the tongue reduces the load on the axles, and thus we could deduce the axle load would be about 2,850-lbs. This gives us more margin on the maximum axle rating of 3,500-lbs.
Another consideration is the load rating of the tires. If the single axle has to carry 2,850-lbs of load, each tire will have to be rated for half of that, or 1,425-lbs.
In checking the load rating for 14-inch trailer tires, such as the popular Goodyear MARATHON ST RADIAL ST205/75R14, it looks like the maximum load rating is going to be 1,760-lbs at 50-PSI. This gives a load margin on the tires of about 335-lbs.

I can add some more information.
My single axle aluminum frame trailer weighs 900# even. The cross beams are made of galvanized steel. There are disc brakes,a swing tongue and a spare tire included.
The loaded axle weight the day I weighted the boat was 3060#. That's hooked to the car.
Total boat weight on trailer was 3440#.
Tongue weight deduced to be 380#. Kind of heavy but that's an other story. It tows great.
