    Boats Position on Trailer

    I have a 202BR Crownline on an Eagle Trailer. The boat always loads on trailer where the the bow is approximately 2" off center of the trailer bow cradle.  The boat appears to evenly aligned with the trailers bunks in front, but the rear is misaligned by approxiamately 2". I need advice on how to adjust. Thanks, Brent

    Adjustment should be based on the transom to the bunks--- should be even to the bunks at the transom or the transom slightly over within 2", but no more.

    Thanks for the info. The transon is a little over 2 inches off center at the bunks. How do I center it up.

    Re: Boats Position on Trailer

    Brent, you say that the boat is off 2" at the bow roller and also 2" at the transom.  Is this at the same time?  When you winch the boat up, does it center on the bow roller?  The boat's transom should be centered on the bunks.  Any adjustment would be made at the bow roller, but you need to have the boat centered on the bunks first.  Have you tried varying how far you back the trailer in while loading?  That makes a big difference in how the boat centers.  The trailer should be backed in so that the top of the wheel wells are just above the water.  If you back it in too deep, it's tough to center the boat.  If the boat's not straight when you pull it on the trailer, try turning the outdrive and giving a little gas to push it in the right direction.  (It's best to trim up some when doing this.) I can usually tell that the boat is centered before pulling it out of the water by looking at the gap between the boat and the wheel wells.

    The boat is 2" off center at the Bow roller, centered on the bunks in the front and 2" off center at the transon in the opposite direction.  I know this would appear to mean that I am just loading the boat on the trailer at an angle, but it loads this way everytime no matter what. I have driven in on, cranked it on, tried varying the depth of the trailer, and even having friends hold the sides straight while I cranked it on. Same results every time. I am wondering that if one of the bunks being  slightly lower in the rear than the other bunk could cause the problem. Thanks for your advice.

    Brent -  when U have Ur boat on a very flat, level surface, and you have all trailer tires inflated equal, measure your rear bunks distance to the ground. (should be equal).  Also, is the stantion for your bow roller straight & true?  Assuming all these point are true,  maybe U have a "crooked" boat...LOLStick out tongueAngry  Or possibly Ur trailer is sprung? 

     

    Here is another "plug" for PRESTIGEWink TRAILERS....With our 200 LS when it is loaded 1 or 2 inches off center (even maybe 3) and we leave it like that and fasten the tied downs, by the time we drive 17 miles home the boat has centered on the trailer!!!!   (Prestige & deep V hull)

    Re: Boats Position on Trailer

    Sounds like you need to check the trailer when the boat is off.  Eyeball it to see if the bunks are straight and take some measurements along the length of the bunks to the trailer frame.  From what you're describing, it seems that the problem would have to be in the front half of the bunks, since it won't let you winch it up straight to the bow roller.  At that point, the boat shouldn't even be touching the back part of the bunks.  You should have some adjustment where your bunks attach to the frame.  Hopefully, Byron will chime in with some ideas.  Good luck.

    Re: Boats Position on Trailer

    I agree with Jim.  Take a look at the bunks with the boat off.  Make sure they are parallel with each other and square with the bow roller.  I had this problem a few years back.  Some idiot hit my trailer (and just clipped the bunk) in the parking lot while we were out on the lake.  The impact caused one of the bunks to misalign with the other and with the roller.  It took me until the next boating trip to figure it out.  As far as how to adjust, in my case, the bunk had a welded support and I had to cut, straighten and reweld that part of the frame.  If this is your case,  look to see if your bunk support is adjustable or possibly see it the bunk itself has slipped from alignment.  Hope this helps

    Wouldn't you know.....every time I send my chimes in for cleaning, someone wants me to use them. I mean I could leave them on the back of my desk forever and no one would want me to chime. That is the way my luck runs. I could fall into a barrell of boobs and come out sucking my thumb.

    Brent, I would agree with our fellow Crownies. It sounds like your bunks are not symmetrical ( ha! I bet you didn't think I could spell that, huh?) from port to starboard. On each of your crossmembers, find the center point and measure from there to the same spot on the port and starboard bunk supports. You will most probably find that the measurements vary as you move forward and it is causing a push off center.

    If yours is a newer Eagle? If so, you shouldbe able to take your findings to them and receive assiatance in correcting the concern.
