Re: Starting new project 1973 Sea Ray 240 SRV
From what I can tell, neither the cracked riser, nor the cracked block were leaking internal I decided to repair with JB weld. I did not get a picture. What I did was take a dremel tool with a burr bit and grind out the crack making it slightly recessed (not more then 1/64"). I then ground down the surface 1/2" on either side of the crack. When I got to the end of the crack I ground the recess past the end about 3/4". After a good cleaning with acetone, I coated the whole thing with JB weld to cover all the area that I ground out leaving it sit proud of the area.
On a related note, snapped off one rocker arm stud, the head will be going to a machine shop to switch from press in studs to screw in studs.
