Just thought I'd post this here primarily for Neil but also for others who have an interest in Evinrude but may not have known that they also made inboards.

This particular unit is a 1922 Evinrude DD, twin cylinder, 4.5hp at about 1,500rpm, serial number DD66070. There were a total of 3,222 of these made between 1916 and 1927, so it's fair to say that they're rare in the US and extremely rare in Aus.

There are a few missing parts eg primer cups and grease cups, that I should be able to source locally. The flywheel magneto is also missing so it wont run as is, however to get around that I will build a buzz coil similar to that used on the earlier outboards, T model Fords etc.

Enough fluff, here she is (without carby fitted):









Regards,
Spiro

Thank you  Spiro ,
A wonderful job again .
It is very similar to the Sydney built 'Vinco' twin one of which I had.
Certainly rare .
Magnificent finish to the flywheel -How did you do that ?

Cheers

G'day Neil,

I spin then them up on a drill press and start by holding sand paper with a grit appropriate to remove any flaking nickle plate etc against the surface. I then move to finer grits progressively, finishing with 000 steel wool and metal polish.

To protect from tarnishing, there are a variety of clear coats specifically for brass, bronze, copper etc available.

Use the same process for aluminium flywheels, but I don't clear coat those.

Needless to say, there is a high potential for serious injury to self if care is not taken.

Hope that helps.

Regards
Spiro

Thanks Spiro ,
So given the colour of the finish the base metal is ?
Copper -for looks - too light
Brass - looks and weight
Bronze -for weight

Thanks

Now we're getting technical  Cheesy

Brass over steel. The steel provides the weight.
