The Merc 650XS was never intended to go against a MOD 50. The 650XS had a stock F-N-R gearcase.
The Merc 650X that later became the 700X was the MOD 50 engine with a small Speedmaster gear case and totally different tower housing.
I absolutely loved my "cheater motor" 650XS that was a totally legal FE/SE motor everywhere but APBA.
In Canada we had great OMC - Merc head to head FE/SE competition for many years because of the 650XS.

The original 3 cylinder OMC engine were not lost foam. That didn't happen till the very late '70's or early '80's. The loop transfer ports were formed into the cast iron liner and then high pressure die cast into the block.

Well..I remember when the Merc 650XS came out 1975 and it did not keep up with the stock OMC 75 if the OMC was rigged and run correct.
Here is the story from Finland and the debut of the 650XS in the UIM SE class. I raced the UIM SE class many years and was never behind the Merc 650XS at the finish line.
The Scandinavian UIM SE Championship 1975 took place in Forsaa, Finland.
Around 25 boats were in place at this beautiful Lake, and Mercury had just released the new 650 XS UIM SE race engine and lots of people was hoping the new Merc could give the OMC drivers a run for the money.
Driver Bo Nilson (6) was backed up by AGB, the Swedish distributor for Johnson and I by Huzells, the Swedish distributor for Evinrude. (1)
The strongest Finn was Mercury’s Bimbo Aminoff and a few more drivers from Denmark
and Norway with the new Merc.
The rest was using OMC 3 Cyl. 75 Hp. Four heat and three counts as normally and a clock start.
I did not know how strong the new Merc was, but I was very well prepared and after
the first heat the good news was that the new Merc was no match (sorry
Mercury) and the fight was as usually between Bo (6) and me (1) and some other OMC
drivers.
In the second heat Bimbo Aminoff took the lead but after a few laps I past him and so did Bo but I made a mistake in one turn and Bo past me
for the win.
Well, I do not remember exactly but it came down to the last
heat and the winner of that heat was the overall winner of the race and I was
the lucky one again with only to tens of a second over Bo Nilsson, and I was now
the Scandinavian Champion for the third consecutive year.
Well not yet, because third was Mercury’s Bimbo Aminoff and he filed a protest.
Bo and I did not have any spray paint on our gear cases.
You where allowed to sharpen the skeg, and sand on the gear case if you still was within the template.
We pass that test easy, but the Chief technical inspector said that you must spray paint the gear case, and ours was just polished aluminum
so he disqualified Bo and me.
Bimbo Aminoff was now declared the winner and Bo Nilsson went nuts.
I know how angry he can get, and it turned ugly. After a major argument we left for Sweden and straight to Roland Rosenholtz, the Swedish Power Boat Federations chairman to tell him the
story, but he was already informed.
Mr. Rosenholtz made a few phone calls to Finland and UIM.
"There was nothing in the UIM rule book saying the gearcase must be painted/or not painted"
After a few days I received the Trophy and the price money
from Finland and I was officially the Scandinavian Champion 1975.
Thank you Roland Rosenholtz

I spray painted the gearcase back in Swedenand lapped the Merc 650XS the next race.
Remember Paul Kalb from OMC racing in Belgium called me and said..
Lars..paint the f*cking gearcase before next race....the problem was the paint alway came loose and it looked ugly.

We could beat the original 55hp OMCs with a 500 most of the time. They had a much bigger lower unit, they were heavier and they were electric start so they had to carry a battery. These factors kept the manual start 50s competitive. Once they upped the horse power and changed to a better lower unit that was it.

Strang probably wanted to build more loop engines back then. The bean counters probably said retooling the entire line costs too much.
