The pictures is between two Mark 55-H housings... One doesn't have a lock washer on the prop shaft and the other has a 7 1/4 X 12 two blade Michigan...(Not Pop Smith)..

Top block on the left is either a KG-9 or a Mark 40, as I can't tell if it has a belt or gears..

Oh, on the cavitation plate of the black housing is a kick out pin...

Far left is a Mark 30 block, then a 44 Block and the black block is a 55E...

The exhause pipes on the floor look like Yamatom 350...but???

Far right is a Konig 350???

Front plates for Mercury's are for 44'S.....

Your questions are too hard...need easy pictures and easy questions...

The Yamatos on the floor are R series.

The top block is a Mk50 not a KG9 or MK40. Neither of them had the boss for an electric starter. Plus the exhaust plate is smooth not ribbed--another indication its a Mk50.

I always thought those blocks would have been great for 55-H replacements... Been a LONG time since I've seen a KG-9, Mark 40 or Mark 50....I just saw the exhaust plate....Should have realized it had a place for the starter, but then I don't think I'd have remembered Mark 50!!!

On the Yamato Racing stuff, I never what any of it was!

Greg, it could also be a VERY EARLY MK55 right? I have one that has only about 20hrs running time on it that I bought from Mike Downing several years ago, but has been sitting ever since (after I replaced all the seals and gaskets though).

Daren, you are most right!!

Those Mark 50 blocks were ran in the extremely early Mark 55. This engine to be authentic should also have the big fuel filters atop the carbs (The kind you thread onto the top of the carb that has an 1/6 pipe fitting, the filter itself is about 1 and a 1/4 in diameter. It also has the early low compression pistons in it and steel reedcages. These Mark 50 blocks were onlt ran in the first two months of production, then Mercury went to the sand cast "grey" blocks.

Putting the Mark 40 Quincy stacks on the Mark 50 and remachining the carb openings for the KA series carbs and running the "big" reedcage really woke those 'ol blocks up. I had one that was just short of AWESOME!! The only other 40 I had that was faster was the crossflow Quincy with two ring turners in it. I still have it too.

I've got a 3rd port Mark 50 block that at some point I plan on restoring with a set of chrome 4 stacks. I thought it is was a 55 as well. It had pipes on it so there was no exhaust cover and it looks just like a 55 otherwise.

But it is in 700 serial group.. Which is what threw me.

Now I am just trying to figure out what they ran for pistons in this thing. No welded pads or the like just the 3rd ports and some mild porting.

Daren, Yep the VERY early Mk55 blocks were also sandcast like the Mk50 up to serial # 833000. But if I'm not mistaken the exhaust cover was different, more rounded like the later Mk55 blocks. The wedge shape exhaust cover on this block makes me think it's Mk50.
