Chip/crack?

 Hi guys could I get your advice on the below pictures?

was out fiddling with the boat today and noticed this underside of port transom. Has only really been out for the test drive. Inspected the boat pretty closely before it was launched and it wasn't there. Launch and retrieval was smooth, and jetty was on underside. Can't see how would have hit something without taking out the transducer. Could a rock do this while driving? Or gouged by the trailer?

is this something I need to be concerned about or get patched up?

im not sure what to look for with fibreglass so would appreciate any opinions greatly!

cherrs, goat.

black rubber?

Wed, 2020-04-01 15:49

 From the pix it looks to me like black rubber from a pontoon .

Are you sure it will not polish off?

i thought that at first too, but i tried rubbing it pretty hard and wont come off, seems a bit roughened too. also im not sure how it would have contacted a pontoon, esp in that location.

Sandpaper . Small bucket of water . Small circles while using Fine grit paper.

Correct me if wrong but is this not a brand new boat.

Would not touch with any sand paper at all.
Lots of chemicals around try small amount of alcohol on a rag ,can also get some hull clean from whitworths .
Then re polish and wax.

P.S
MY theory is the boat has bottomed out when launching it ,could not be rollers as it is at the back .

 As per scubafish advice, try some fine fibreglass polish first or even auto polish.  If its rubber based it should come off.  It should fixed those other marks either side of it.  Any cracks should show up after a bit of a light polish

thanks guys, appreciate the advice.

 

i will give the polish and wax a go.... im assuming just like polishing/waxing a car? clean, then use rag? thought aboutt bottoming out, but fairly confident i didnt as backed all 4 trailer tyres completely under so was fairly deep, and would have take out transuducer first.

interestingly enough is simlar mark but much smaller under transducer on other side which is strange.

appreicate all the advice! pretty nervous to just take a punt on my own  as is new and i still have a lot to learn!

 I'm curious, how did you go

 I'm curious, how did you go with polish?   By chance, if this the new Caribbean that you posted a pic of on 29th (nice unit btw) I'd check the two rear trailer skids, could they have made contact when fitted?  Just a thought.

 maybe drop the leg of your motor right down and put it on full lock each way to see if there is anything rubbing

 Hey guys. Thanks for all the input! I'm beginning to wonder if they are marks from when it was lifted by the forklift ey. As appear to be exactly same spot each side. 
I haven't been able to get to them yet as a bit hard to get out and about to grab the materials. Plus not really rushed as limited ability to take it out at tmr moment!

once I get onto it I will let you know the outcome!

thanks again for all the help!

Good luck, as others have

Good luck, as others have said, I would try and cut and polish first. I've had good success with similar looking marks using the Septone Fibreglass Buffing Compound.
