Converting Gasoline Pressure washer to Electric

My first ever Ben Nelson Style Gasoline to Electric conversion.

I've got a Gasoline pressure washer with a shot 3500 rpm (rated) gasoline engine, and a 3450 RPM 2HP continuos duty 110 volt motor from an old air compressor that blew a head gasket and was upgraded (now 16.9 cfm @100 psi).

I figure that they should go together, I'm guessing that I may need to run higher flow nozzles, but that is a bridge that I'll cross when I get there.

Pump has a female 3/4" keyed shaft input, and the motor has a 5/8" flat shaft.
I just ordered a 5/8" set screw type coupler and a 6" piece of 3/4" keyed shaft.
I am planning on turning down the 3/4" shaft on one end (in my lathe) to fit inside the 5/8" coupler. Then assembling as follows Motor with 5/8" male shaft->Coupler with 5/8" on both ends->Custom 5/8" male in 3/4" male out shaft-> pump with 3/4"female input.

Also Planning on making "L" Shaped braket to hold motor at bottom and pump on face with over size holes for adjustment.

Any ideas/ comments are highly welcomed.

Few Pics
Pump Top with adjustable bypass (probably will need to be turned down)



Pump input, feels like it has 2 bearings, anybody think I should tear it down to find out?
