lower unit damage

[speck-chaser]

My son hit something underneath the water with his 15 hp mercury yesterday. He noticed a lil oil slick when he stopped, then found a gash in his lower unit. Im wondering if a lil jb weld or something of the sort will be enough to fix this,or will I have to get more drastic? I know I will hafta change out the oil once its fixed,because of the water intrusion. Just needing some advice.

I have no experience with JB weld to fix a hole in a motor.

I tried JB to fix a hole in an Al John boat. It held up for a while but then started leaking again. After a couple fixes..... I got it welded up.

Give it a try...... but don't run the engine if the oil starts to turn "milky" white.

Like we discussed,you can try to patch it but I would not recommend it. Even if you got someone to take it apart and weld it the sealing area will be hard to shape.Bring it to Cade at the prop shop I have seen him make the impossible possible,tell him I sent you.

I have some stuff called "Splash Zone Compound". I used it to build my nosecones on my racing lower units, and the leading edge was sharp as a good knife. Never had a single chip in the stuff. It is harder than the aluminum on the gearcase. It is sold in two parts, a compound and a hardner, one is yellow the other is black. When mixed it turns OD green. When you apply it, you can wet your hand and smooth the surface as smooth as glass, it is sandable, cures in 24 hours. It bonds by physical adhesion, so rough up the area very good with 40 or 60 grit sandpaper, then clean with brake parts cleaner, NOT CARB CLEANER, carb cleaner contains oils brake parts cleaner does not, and apply. It even dries underwater. Shoot me a pm if you are interested, I would trust this stuff to patch almost anything.
