Best way to fix this damaged fiberglass section of my 40 hp Merc's lip?

[Expidia]

Just got my 40 HP 2007 4 stroke outboard back from the shop. Had an incident last week where the outboard over heated, but shut down automatically. But a few components got real hot and a pinhole leak in the fuelline caused some flames when I picked up the cover. I put cover down and grabbed the fire extingquisher but the flames were already out when I picked it up again to foam it. I foamed it down anyway since there were 4 of us onboard and it stopped on the river just outside the channel. It melted parts of the wire harness. They replaced the harness and other parts and said they test drove it on the water and it runs great.

The only residual cosmetic damage left is the small section of fiberglass in the pic because when I dropped the cover down two wires were hanging outside the cover and arching until I cut the power to the batteriy off.

Any ideas how I can repair this section of the fiberglass lip. I know its only cosmetic, but that damaged spot still bothers me?

1st thing is glad you got the fire out quick and no injuries!

Just an idea and others may have better advice - You could grind a little to get a good surface, use some tape to make a mold and fill it with peanut butter epoxy mix and then sand it to shape. Hit it with some Merc Phantom black spray paint to cover the repair.

That sounds good GA. Thats the info I was looking for as with the peanut butter expoxy which I nver heard of. I'll try that for the repair

If you do a forum search for peanut butter it won't come up with Jif. :smile:

If you see a recipe by Friscoboater, that's a good one and others have their own mix.

Since I was still tankin' up on coffee when I posted earlier and I'm awake now, what you might do is grind enough so after the peanut butter is sanded down, a strip or two of fiberglass cloth can be laid on top and then do the final sand before painting. Might be less chipable with some cloth on top.

Thanks GA. After your first post I did search for peanut butter expoxy on Amazon and found nothing. Once I can find something similar I can try the glass overlay. The only thing that actually hits that spot is the rubber gasket of the outboard cover.

Search our forum for peanut butter. It's a batch of resin/filler you mix yourself and a clean Jif jar can be used. Label intact, of course. :smile:

I neglected to ask Woodonglass for his PB expertise. Blamin' coffee again! :blue:

Here's how I'd fix that. I'd use PC-11. Drill two holes on either side of the lip and then after you've mixed the PC-11 into a clay like putty, use your fingers to mash it into the broken lip area then use a moistened ftat head screw driver to shape the putty to the shape of the lip. The putty will fill the holes and act like small rivets to hold it in place. PC-11 is epoxy base so it's very strong. Make sure to clean the area REALLY well with Acetone and a Wire brush. When you're done she'll look like new

Thx Woodenglass. You fix is what I'll try.
