Outrage II Static Trim question

I noticed recently, that my 17 OR II lists ever so slightly to starboard. This is based on the bottom paint lines. Looks to be about 1-2 inches lower in the water on that side. Interestingly, this is on the same side the oil tank is located under the stern seat.
Is a full oil tank (4-5 gal.) enough to cause this slight list?

prm1177 - I doubt that the oil tank would cause it -but I have not made the calculations. Now, I think the tank is about 4 gallons (full) at what? - maybe 7 lbs/gal - or 28 lbs max which is not all that much. I have basically the same boat and my oil tank is typically around 1/2 full - well between 3/4 and 1/4 full.
Incidently - have you removed the nylon plug in the forward wall of the under-deck storage area - close to the bilge pump? If not, remove the plug and see what comes out - it drains any water from around the fuel tank area - but I would expect that area to be centered.
In the meantime - in the next few days - I will make some calculations and see what comes out. --- Jerry/Idaho

Is your oil tank really 4-5 gallons? The tank on my 19 outrage takes about a gallon to top off after the low oil alarm goes off at about a half gallon. The main tank on ours will need fuel before the oil tank gets low - if both were full to start with. Joe

Joe - I initially questioned the same thing - and then guessed (I would measure the tank dimensions, but my boat is covered for the winter) that the tank on my 17 Outrage was about 10 x 8 x 10 which is about 800 cubic inches. There are 231 cubic inches per gallon - so the oil tank is about 3.5 gallons. Though when I responded earlier - I came up with a bit over 4 gallons. With the tank full - and with oil weighing maybe 7 pounds per gallon, that says 28 pounds. And like I mentioned, on the average - my tank is about 1/2 full. But even so - I would not think that 28 pounds would cause a problem - but I've been wrong before. ------ Jerry/Idaho

Hmm.. that sounds about the size of my tank but I too am stored for the winter out of easy reach. Sure seems like a lot compared to a 5 gallon bucket. Maybe the distance off the center line of the boat? I am not familiar with the 17. Maybe the bottom paint lines are not true side to side? Whatever the case, is an inch or two a lot for a boat of this size? Joe

I suspected the tank had some effect since filling it to the top increases the trim difference. When it's about 1/4 full the trim seems closer to normal. Didn't want to start getting paranoid with visions of wet foam on one side. The boat's been in the water since April, but the bottom was prepped correctly by the previous owner with an epoxy barrier coat and ablative bottom paint. The only other item on that side is the sonar sensor and paddlewheel (installed at the original dealer).
I will pull the tank plug when we take it out for off season rack storage and (shudder) see what comes out.

On my boat the battery is located in the cc about 1' to port of the center line, the 3 gallon oil tank is in the starboard stern seat about 2 1/2' from the centerline. The battery weighs 45 lb. and 3 gallons of oil weighs 20 lb. This would equate to about a five lb. difference. I don't think this would be enough to cause the list you describe. Is the list new? Has your battery shifted, or been mounted to the starboard side of the centerline?

Why wait to pull the tank plug? Any water that comes out can be pumpued out with the bilge pump.
