Brian,
I used a two part Steel Putty called Devcon 10110 for a repair to my Mercury 3.5 HP Outboard impeller housing. I'll enclose pictures of the product.
A well meaning friend "helped" me one day when I was changing the impellor and over tightened one of the 4 bolts that hold the top cover and Gasket to the bottom gear housing. Stripped the bolt and cracked the top corner right off.
Hey, guys got one hell of a grip!
As it's part of the lower housing and being a very expensive part to replace I tried this Devcon.
The stuff is "steel" and acts like it.
I packed the threaded hole and reshaped the top corner and waited a week before even touching it.
It drills and taps as if it was built with the lower unit from the factory.
It's been doing it's job for over 10 years, it's a 2000 Mercury Outboard.
I even used it on a friends 340 Auto Pilot engaging handle, behind the wheel. It's a tough spot to get into and it cracked on him at the hole to mount it with a bolt. It's been going strong almost as long.
If all else fails for you try this Devcon. I think it will do the job for you. Read directions carefully, proportions are critical for maximum strength.
I know I bought it a while back and paid about $29, shop around though. Hope this can help you out.
