View Full Version : Easy fix?

Sorry about all the threads lately but I'm really trying to find the right boat before the summer and you guys have been a lot of help. That being said, how hard do you think it would be to fix the gelcoat around the damaged area in the picture? This is right around the hinges of the sundeck and there seems to be some stress cracking, but i'm not sure if this is fairly common for a 12 year old boat. Further, even if I got it fixed, how could I prevent it from cracking again? I'll hang up and listen :D

Minor, you could 3M 4400 that for the time being.

Does the cracking not alarm you at all?

Not me. The spider cracks happen a lot to older boats.

in that particular spot i wouldn't get excited. in other spots i'd be concerned. my boat has a similar but not as bad issue around the starboard hinge for the sun pad. my guess on mine is that the gas shock was shot and folks just had to force open the sun pad manually. that extra force probably caused the hinge bolt to loosen up and allow the hinge to rotate back into the gelcoat which caused the gouge. my sun pad is currently off for reskinning, however, my plan for a fix is to replace the shocks (done) and to tighten up the hardware and use my basic gelcoat repair kit from bass pro to touch up the gouge. i'm not worried about further stress cracking because that hinge really only seems to be under stress when the sun pad is up. when it's down, it rests on metal cross supports so the hinges don't really seem to carry any weight during normal use which should hopefully alleviate any further cracking.

Well I decided to have the gelcoat fixed this winter and it looks really good, but my question remains on how to prevent this from happening again? I thought about using something like clear furniture bumpers, but nothing seems to want to stick to the gelcoat. Next I thought about some clear marine adhesive like this http://compare.ebay.com/like/280938091408?var=lv&ltyp=AllFixedPriceItemTypes&var=sbar, but it is too permanent and I want the ability to remove it if the next buyer doesn't like what I've done.

What do you guys think about just putting some clear silicone back there? Do you think it will stick? Any other ideas?

The gel probably has a fair amount of wax on it depending how it was repair. IMO the only thing to minimize the re-occurrence is to take some of the load off the screws. Did your sundeck flip all the back to cause the chipping in the gelcoat?

In the first picture posted it looks as if the hinge rotated more than 90 degrees to make that contact. As mike said. Are your gas struts not connected or wrong length? Hinges loose on the sundeck. Has the previous repair been too bulky and intruded on the relief for the hinge? Maybe open it up and take a photo.

You can't fix that without sanding the old off and giving the new something to grab onto. If you scratch/gouge out the cracks, you'll just end up with stripes of a different color, even if the gelcoat repair is supposed to match.

That deck rotated too far- I suspect that someone pulled the pin on the actuator and either accidentally let it flop back or the wind took it. It can't do that without one or the other- if you remove the pad and rotate the hinges, they'll match the gouges exactly.

Keep it from moving too far, don't over-stuff the storage area and don't twist the deck.

Actually Jim the actuator does allow the deck to go back too far. I've witnessed it and you are right that the hinges match the gouges exactly.

But the point of my recent post was to try and figure out a way to prevent it from happening again. I've had the spots sanded down and re-gel coated. It looks like new now. But I'm trying to get it where it doesn't gouge anymore. Thus I thought about putting some rubber bumpers or some silicone back there to keep the sundeck from hitting the gelcoat again. If I leave it as is, someone could let it go back too far and it will gouge the area out again.

I'll try and post pictures later, but the boat is in storage. I don't think the screws were loose allowing excessive movement, but I haven't checked the gas shocks yet. I assumed the original ones were on there since the previous owner didn't change anything else.

Is there anyway to adjust the height of the actuator to restrict it from extending out all the way?

If the hinge is over rotating just a bit then how about grinding the hinge plate itself so that it has a concave recess. This should provide enough clearance if the is only slightly intruding into the gelcoat when the deck is fully opened. Would that work?

Maybe shift the mounting points for your struts or order some a little shorter with the same pressure?

I suspect the end of the actuator attached to the deck and used to raise it was moved toward the stern. Disconnect the end of the actuator and reattach to the deck 6-10 inches closer to the bow. When fully extended it should not over rotate the deck so much that the hinges hit the stern deck.

Do you see two sets of mounting holes for the bracket that attaches the top of the cylinder to the under-side of the pad? I would remove the bracket and see if it has threaded inserts. If not, I would move the bracket farther from the back edge. That makes it open less but yu don't need to move it far.

For climbing into the storage area when servicing, I used a rope with a clip to loop around the T handle or the bracket that could be moved. I then pass the loop on the other end of the rope over the ball on the pylon. The rope was cut to length so it won't let the pad open too far.

First, I think what everyone has said needs attention first. However, if you have access the the underside of the deck, you could add some glass and a piece of 1/2" wood around that area to help stiffen it up. I think this would help a little, but as long as the hinge is over rotating, you will still have the problem. Possibly a good place for a custom sticker? I know that would be covering it up, but it is really just a cosmetic thing and unless it over rotates to the point where it tears the glass, then keep on keeping on.

What about one of those rubber little round pads like those that are on kitchen cabinets to keep them from slamming to help prevent any gouging? Just a thought.

If the bumpers are thick and firm enough, they can actually add stress points.

I'm going to go through all the things mentioned this weekend and thanks for the responses.

I was curious about those bumpers causing stress, but I thought it might protect in a worst case scenario situation and then just make a habit of not raising the deck all the way up. However, I couldn't get the bumpers to stick to the gelcoat so I'm wondering if a bead of silicone will work just as well.

Regardless, I hope that I can find the source of the problem and not have to rely on anything else.
