What is in the top picture ?
Looks like the inside of a Catalytic converter...

FYI. Have a buddy with those flaps that poked a hole thru a cylinder wall after coming off plane at an angle and the flap didn't do the flappy thing. After some use they curl up a bit and take a set to where they don't full seat flush against the outer lip. Just keep an eye on them.

Well the starboard engine is down for the count. After I had it running I put kroil penetrating oil in the cylinders to aid in any rings that may not have loosened all the way up. Well after letting it sit for a couple days I was going to rotate the engine by hand and fill again. To my surprise the engine had a hard stop and I could only turn the engine 1/2 way in either direction. So a couple days later I got around to loosening up the exhaust manifolds and removed the valve covers. The rockers were loose on cylinder three and the push rods got bent to crap, havenít got into the bottom end yet but Iím guessing the piston is smoked. Got a good amount of rust in the valve covers and the push rods covered in rust so I am assuming the cylinder walls are in the same shape. Next up Iíll take a look at the port engine and see how it looks.

Slowly plugging away on the boat now that the kids are back in school/sports. Got the stickers peeled off the sides of the boat. I have since used a color restorer on the boat, still a long ways to go. I pulled the out drives off to store in the basement for the Michigan winter. Working on tearing down the starboard engine to identify what it needs over the winter so I can rock and roll in the spring.

Finally got the intake pulled off, it seemed easier to leave the carb on so thatís the route I went. As I dig deeper into the engine it looks like Iíll be also digging deeper into the wallet. 😬
