C service Speeditwin racing motor photos

[MTECHMARINE]

Attached some pics of the SR all ready to go.

This thing is a work of art, everything has been done that you can imagine. The gearcase is Wiseco. I used up my last new Vacturi on it, the VR will have to get by with a used one.

Nice work;
-I finally reskinned my DeSilva /Speeditwin CSerR and showed it at our local show last month. The motor is a Stan McDonald.
Will get some closer pix.
Q? -my SR39 has a bronze aftermarket(?) saddle, which I think yous has also?, but my PR 65 does not. If it was needed on the B motor,
why not the C motor?

Really nice Brian!

Really nice Brian!

Thanx; -it has not run since Sydenham ON ~2000.
Looking for CZ-1 to come out again?
Who was that tall guy in the cockpit?
Maybe a grudge match in Gravenhurst,
if they race there next year?

Great job!! What is the model number of this beauty? Or the full number on the front tag... Thanks!

Just finished up restoring this motor. it is a 1934 Evinrude speeditwin modified for C service.
Originally owned and raced by Sid Sato in the Pacific Northwest.
I embellished it some with an earlier gas tank with "Evinrude" stamped in and an abbreviated muffler can. Left the plugs out so as to not gig myself on one when walking by.

Thanks for the prop, Ron!!

It is set up to run on gas rather than fuel.
You other C service collectors and racers, lets see your motors!!

There's no numbers on it anywhere that I can find. The bracket is newer, the plate has been removed.

BTW, I have finished up a 3rd motor, a PR65. I have no history on this one, it came from a South Georgia estate. Here's some shots.

Another beauty! If there is no number plate the number should also be on the block front side to the left of the carb at the very bottom edge... Mine has the same number there as it does on the front tag... Thanks.

Where does a P-50 come into play? My dad had a P-50 he raced in C Service.


This last motor looks like it has Hubbell "HORNS". Not many were made, my brother had a set on his Evinrude 60-42. But the Quincy's Cross Flows were killing the PR's by then.

I'm driving my brother's Sid Craft with the Family's 60-42 Six Stud Evinrude on a Merc midsection and gearcase, with Hubbell "Horns".

P-50 is a service 30CID from 1930. This the 1st year for that model. VR45 and SR45 were 1929 emissions with a full speed rotary valve. each year the model went up by 5, sp 1 "65" would be a 1933.

The "horns" look great, but they restrict the exhaust so severely I can't imagine they did anything for performance.

I had a Hubbell PR that I sold to George Taylor that has really large open chambers for the exhaust. On my SR they actually cut away the cylinder shrouding the outermost exhaust ports.
