Default Hull Heat Damaged?

Didn't notice this because I just held my hand under the stern and snapped a photo. When I looked at the pictures later I saw it.

The discoloration and cracks are located near the stern outdrive beneath a 5.7 Volvo motor. Inside hull looks clean but cant really see beneath the motor.

Is this from internal heat? Is this from hitting some object? Is this bad? ;?

Looks like rust on very thick and cracked bottom paint to me.
really can't see a hill getting affected by heat unless it's on fire.

I would say cracked and dirty bottom paint. Water draining from the drain plug most likely caused the discoloration.

Sand down to the laminate and see if it extends into the glass, if the crack extends into the laminate you have a problem.

This is a boat Im thinking of purchasing. I am gonna get a hull survey tomorrow. I will say the interior of the hull looks good for a 1995. I tapped the outer hull especially in the transom and below. I heard the typical and consistent sharp report of solid hull and no dull, lifeless thuds. I didn't get down on my hands and knees to look at the bottom, just crouched and snapped a few pictures. The bottom paint is original and actually a bit thin. You can see other areas where it has chipped away to white. Boat was never slipped always trailered according to the seller. Hour meter is at 1046. 5.7 Engine is completely rebuilt with receipts and so it the Penta duo prop although I took pictures of the bellows and they had some surface cracking so I have to ask the seller when that was rebuilt.

Sorry the photo is a bit blurry.

just make sure you pick a surveyor that is qualified, some don't know much more than a tap with a mallet. some are engineers.

Looks like some one has done some filling and the filler is about to crap out and fall off , because its right at the back could have been worn away so yes a grind and inspect !!
HEAT you must be joking !! what would make you think such a thing ?

Not heat but sometimes you see that on sterndrive boats from rust in the exhaust system. The cast iron exhaust manifolds and elbows put out a good bit of rusty water and it will run down under the transom mount and run back along the hull depending on how the trailer is tilted. The crack would concern me. I'd get up in the bilge and look under the engine right in front of the transom mount and see if there is anything suspicious there. If I were going to buy that boat I'd want the old bottom paint there removed to make sure there is not old damage.
Is the owner the original owner? He may not be due to the bottom paint. If it was always slipped why then is it bottom painted? No one does that unless they have to, due to in the water storage.

You know what it looks like? Owner was towing the boat, it came part way off the trailer and dragged on the ground, then the rash was filled with body filler and painted. Now the paint has partially worn off and the filler is cracking. Hope I'm wrong.

My god you really come off as an arrogant dick, I have seen it in other threads and other users mention the same thing about you and I why.

Back to the OP it does look like rust bleeding through a crack and I agree with others that it needs to be ground out to see the severity of the issue you are facing. Good luck OP.

Looks like ramp rash and a slather of resin to me. I can’t get the attachment to expand for some reason though.

I believe that your area of concern is water stains which can be confirmed with a scraper but it looks like the mechanic that installed the transducer had 10 thumbs and I'm concerned about the fairness of the hull forward of the transducer. It looks to me like there's some humps and hollows that shouldn't be there but the quality of photograph isn't very good.
And the bunks on the trailer are rotten.

Im trying to figure out why its so shiny. Looks like someone just brushed on a bunch of epoxy resin in order to hide something.

I got it to expand off my laptop. It looks more like bottom paint that is cracking and peeling off, with dirt, etc in the cracks. In the middle of the area, there is about a 2x2 area that completely came off and you can you can see the clean bottom of the boat under it. Might possibly be due to improper prep before painting. But Id still like to know what the surveyor says. Personally, Id take a scraper to the area to double check but it doesn't appear to be that bad from the poor quality picture.

It kind of looks like the same color as the two part epoxy you get from a hobby shop for model airplanes.

Not heat related. whatever it is

It looks like a stain combo of oil and rust. I bet it's the same color right below the drain opening.
