Emergency/Provisional repair on Etec60 2012 oil tank

[oceanview2]

I've discovered a seam leak in the uppermost forward port corner of my oil tank.
Drips only when the engine is tilted up full.
Apparently some other Etec60 owners have inherited the same defect. Until I can get my boat to Evinrude for my three year service is there anything I can put on the three inch long seam site to arrest this leak. Also plan to remove the oil to 50% capacity.
Thanks for any advice.

That stuff looks good, never heard of it but back to the tank, they obviously have a problem as ours cracked but halfway down, which they replaced.

Probably nothing is going to bond to that tank. I think the SUGRU is pretty neat, I have used it, but my guess is that the tank is polyethelene and that plastic is known for resisting any glue (think milk jug).

Anyhow, the best way to perform a repair, not patch, is to weld the tank. I use the Urethane Supply airless plastic welder all the time. It has paid for itself many times over. About $170 at Amazon. The kit comes with directions and a selection of weld rod for a variety of plastics. The stainless steel screen when used adds quite a bit of strength.

I use this all over the cars, on the refrigerator interiors, the swimming pool filter housing, most anything made of plastic.

Robert, do you think that will work to weld the moller gas tanks? I spilled TCW-3 on one of mine, and I can see that the oil damaged it to the point that it will eventually fail on me. Problem is new ones don't fit, so...

I have personally welded my Moeller gas tanks. There is a learning curve but repairs can be as good or stronger than original.

Now, if yo9u damaged an area, you would of course need patch material - another fuel tank?

As far as the fit of the new fuel tanks - I finally figured out, after getting a free replacement on one of the tanks from Moeller, that if you use the old style fuel cap, they should fit.

So my tanks both have different style caps. Both fit. I'm wondering if I have a new style and an old? I'll take photos next time I'm aboard.
