Pressure washer PSI rating to clean engine bay?

[HuskyMan]

I'm looking at pressure washers to use to clean the engine bay, both top and bottom. I'm thinking of using a presoak of Simple Green or some other brand of degreaser then scrubbing lightly with a brush to loosen the grease and grime. I'd also like to use the pressure washer to clean the driveway, roof, brick and vinyl siding, wood and vinyl decking, etc.

Question: is 3000 PSI too much power to clean an engine? Could water sprayed at 3000 PSI sprayed into an engine bay hurt or harm either the engine or electrical components?

Would I be better off with a 1700 PSI rig? Your opinion is appreciated.....
