Mark 20H Merc racing motor

[PornstaR16L]

Everyone hates me due to I have extra stuff but i continually look for motors all the time. I grew up running the kiekhaefer and the seahorse motors.... so I must hoard them. LMAO

[PornstaR16L]

actually have a couple cut and 2 uncut. But sorry none for sale. I actually have the entire K series fully restored in fishing form. I have a couple conversions like the one you are building. Im a collector, and stingy with my stuff. Where you located??

[PornstaR16L]

None of you know what you are talking about. This is a Mark 20H with a quicksilver lower unit (tuned port exhaust). Stock this motor was a race motor. "H" meaning hydro lower unit and it came from the factory with being the 20H. Was the only motor to come with green and gold.

@PornstaR16L yup, has the popper midsection which is also "race".

[PornstaR16L]

@cpgixxer The mid section was dubbed "the thumper". Mark 20H was used for B stock classes. This mid was used in the B modified class. I ran this for years and still have 2. Then retired them when OMC burst on the scene and I swapped to Yamato 20SSH/ C class

@PornstaR16L I'm building a kg7h with a mark 20 powerhead with the H tower right now, got any 20h cowls for sale? lol if I can find cowls it will be mark 20 powerhead with a kg7 tank running the aj32a carb, it will look and go like a kg7h.

@PornstaR16L other common terms for the conversion kit are "Toilet Bowl" and "Popper" exhausts. This engine is still legal and somewhat competitive in the the BSH class in APBA. They are also run in vintage races. I myself am finishing building one and plan on having a video of breaking it in.

[swarne8]

[agentxpp]

re mix your fuel and get a mechanic to adjust your carbs,

should run better

[mikedarrow]

needs a carb adjustment

[mikedarrow]

I believe it's taken to much gass

[boatdaredevil]

where can i get one?

[Silenius08]

I would love to find two of those engines. One would be stock as it left the factory and one would have the factory upgrade kit, ie, the changed carb and exhast system.

[boatdaredevil]

Did you no nothings ever run an outboard?? Looks like two five year olds playing with something they know nothing about..

[bsboats]

Mercury Marine temporarily shutdown all manufacturing operations in Fond du Lac, Wis., to better manage its inventory supply line.

The engine maker gave nearly 2,000 hourly workers a week off, without pay.

[Synthomania]

[fangus503]

That was pretty funny when you scared the sheist out of that old lady.

[jeff59s]

Thanks for this video, makes me laugh so hard every time I view it. Reminds me of my childhood.

[saabdude67]

That's gotta be the richest I've ever seen an engine actually fire at! haha

[HersheyWC]

Scared the crap out of that old lady trying to help you though, so that was entertaining :P
