Marlin Transom flex.......Not flexing

First I heard this. How bout some more info and pics.

2005 300 Marlin w/F250's
 
I read in earlier posts on another forum of this issue about 6 months ago. Never put 2 and 2 together until 3 weeks ago. I was concerned about the narrow rack my Marlin is stored on at a Grady dealer. Pushed up on the stern rub rail and sure enough it moved vertically 3". Assumed it was rocking on poorly canted bunks......wrong. The stern was flexing from only 'my' hand applied pressure. This is probably my last public post on this thread.....unless someone from Grady White wants to chime in. Or, anyone that has gone down the path of having this fixed.


Marlin 2002 F225's.......Boat and Engines have less than 175 hours. :?: :roll:
 
Love to see a pic of three inches of movement with just hand pressure. That seems very excessive!

i hope before you make this your last post, you'll explain exactly what you experienced. for the life of me, i can't picture what you are describing. did the liner separate 3" from the hull? did you move the entire boat 3" with just your hand? i can't figure out what you meant. ron

Yes, I moved the entire boat 3" by hand pressure. I purchased the boat used and have no relation with the Grady Dealer where it currently resides. I'm calling Grady White Corp. today.

The other Forum is The Hull Truth.

you should make sure you are connected right to eddie rowe on this. also, sorry, but i still don't get it. you were able to move a 5 ton boat, on the hard, with hand pressure. still can't picture, but make sure you clearly explain to gw. also, did you get a certification that there was no damage to the boat with the prior owner - unfortunately, some people have no scruples. good luck, ron

Thanks! You have helped me in the past as well.

Survey came back structurally 100%...my guy even climbed into the bilge (tight fit). Not sure if anyone actually tests for hull flex. No, I'm not superman and consider myself 20 pounds overweight. Yet, I am still able to vertically push ONLY the starboard transom slightly straight up. Not the 5 ton boat.....just the aft starboard section. I'm pushing up on the rub rail. If I put my back under the boat and did a squat type of lift......I'll bet she moves even more. Called GW this morning and the dealer is looking at it now.

wow thats not good, sounds like something gave way under the fiberglass? Any small stress cracks in the gel coat?
 
No stress cracks ANYWHERE on the boat. It has less than 175 hours on boat and engines. It has a unique history and has been captain maintained all it's life. Not sure if it ever experienced anything over 3' seas.

I am having a hard tim finding it on THT. Can somebody post a link? Thanks!

It was on one those Grady White VS Boston Whaler threads or Grady White value threads. Actually, I think it is buried in the Grady White vs Hydra Sports thread. Someone claimed to know a GW executive that said the Marlin transom was redesigned at some point due to 'visibly flexing' of the transom.
 
any way you were actually "rocking" the boat (no pun intended)?

if it was balanced just so, i can easily see moving the boat with a little force. i'll keep my fingers crossed for you. ron
 
I can tell you when I bought my 330 express used the survey missed a small crack in the forward chine, when I got the boat home I called G/W and they sent an engineer to look at the boat in orlando fl. I bought the boat in january and wanted to use it some they said no problem they would have someone here fix it or pick it up and bring it back to NC for the repair, my choice. I fished the boat til labor day and then called G/W to see about the repair they picked it up in daytona beach and trucked it back to NC and reapired that and a lot of other stuff that they did not have to. I would not worry to much G/W is a standup company and will bend over backwards to keep you happy. Good luck and keep us informed.
 
It doesn't sound like the whole boat lifted off the trailer or jack stands, just the right side of the transom actually flexed upward by 3 inches....as if there were no core or just a single skin of glass....which sounds absolutely crazy......the fact that it could move that much and not crack the gelcoat is simply amazing.......I've never anything like this before.....hard to contemplate.

that's what i was thinking. i'm not saying the whole boat lifted. i was speculating that maybe it was "balanced" and the force caused movement. kinda like trim tabs. port tab down, port transom up, starboard bow down. just a thought. ron
 
Not inclined to post pics since GW is looking at what I observed. I'm leaving this to the experts. Maybe this is within load tolerances of the design.

Outstanding support on the 330 repair. I'll bet only a handful of manufacturers are stepping up to that service level in this economy.
