SF18 weighs in at 3,000 lbs full of fuel,rigged

[CaptSeaCraft]

I finished my fuel feed line and vent hose replacement last wekend so I thought I would fill her up and put the downriggers,tackle,and kicker on to see what she weighs in at.I put her over the scale and unhooked.she weighed in at 4060lbs on the trailer.I launched and left her at the dock and went and weighed the trailer.1060lbs.-4060 gives me 3,000lbs even.I thought it would be a bit more.has anyone else weighed their SF18 Potter rigged and fueled?As for the fuel service line replacement and breather line replacement....I hope I never have to do that again!Now its time to Fish!!!!

Whats the size of your fuel tank? and motor weight? I think I will weigh mine as there is a scale close that I think charges $15.00. Sounds like my 3500# trailer might be overloaded!

I've got a 60 gallon tank shoehorned in and a 375# motor. Make a list of everything in your boat and weight of each item. Its amazing how things add up.

Hey Cappy,
Were you able to pinpoint that fuel problem? I must have missed that post.
Never would have thought the weight was so high in the 18...

Hey guys....
Yea I pinpointed the problem all right....There was a kink in the main service line where it bent back to the fill neck.I had a stinless U bent to acomidate that turn .I also found that they used about 12 feet of fuel line,I used 10' only when I refit using the stainless bent U.also the vent line was way too long and it must have had a big droop to it in the hull because it was ful of fuel and could not vent the tank.....thats why gas came out right away upon filling up originaly.I made a loop with the new vent line above..on top of the tank and made sure that I used just enough hose to get to the vent.This way the gas that makes it into the vent line will go back into the tank.here's the pics of what it looked like when I got things apart.prety nasty.I dont wish that replacement job on anyone.The main service line was date stamped 1979 and really was hard and crusty.if you are gonna do it to your boat....be realy carefull clipping the metal coil found in the hose when you get to the point of removing it from around the neck of the tank..I saw a spark jump off my sidecutters and its scary.I jambed a niquil cup in the fill neck to keep the explosive danger to a minimal.

As you'll see in the pictures,I had to put a pie plate at the point where I had to cut the original hose to get it out of the hull.Also I couldn't reach the back of the orig. vent so I put a new one.I worked from the Bow where I had to pull out the docking light I just recently put new bulbs in and resealed last month (By the way...I have a set of round Morse Docking lights for sale if anyone want them cheap)but at least I had a way to get to the fill spout to replace it and the ground line I also replaced.here's some more pics of the new line and vent.

I am totaly finished now and am glad I got to clean out that area of the boat and reseal the hatch and console etc.
.....in the pics you'll see a brass U turn,It was too big and heavy to go on top ofthe tank and it was never used.
have a good one,steve

47 gallon Sportsman's Industries Inc. Tank and I believe the 90HP V4 weighs in at 310lbs or close to that and I run 2 jumbo batteries.I had my trolling motor(4stroke 9.9 yamaha),electric downriggers and downrigger weights on the boat for the weigh in so there's about 250lbs +- that I only have fitted when the salmon are running.Let me know what your boat weigh in at.thank you

Thanks for the reply!I would think most outfitted SF18's would weigh in between 3000-3500lbs.Thats great that you have a 60 gallon fuel tank!

'72 Seafari 20'. Hull 1800 lbs; motor 90 Opti 375 lbs; fuel (main tank only) lbs; 3 anchors, chains and rodes, 75 lbs, 150 qt cooler (full) 60 lbs; rods, reels, tackle 40 lbs; miscellaneous "stuff", 50 lbs; Old 18-20T (3500 lbs rated) TragicTrail tandem trailer 885 lbs = 3,460 lbs.

I "upgraded" the original tires on the trailer from four 4.80'x12' "C" tires rated for 930 lbs each, to 175-13" "C" tires rated for 1335 lbs each, as the only difference from the suspension on the 18-20T and the 19-22T MagicTrail suspension carriages was the tires.
