2000 powerhead upgrade

[chrisbil]

Hello guys,

I recently purchased a boat with a 1998 175 Evinrude FICHT outboard. The previous owner had trouble with the powerhead and in June of 2000 OMC sent him a new powerhead. Would the new power head be a FICHT ram powerhead or a FICHT power head?

Also, can I use the xd100 oil? I have purchased a case of the xd50 and I was thinking about turning it in for a case of xd100.

Thanks for your help

Chris

If the motor computer (ECU) is on top of the engine and has fins for air cooling, is still a 1998 engine block. Also you can tell if the injectors use a big hex nut to fasten each one to the cylinder head.

A FICHT Ram uses a water cooled computer that has a black plastic face on it that says FICHT. Also there is an exhaust backpressure sensor tube in the lower stb. side of the block, and the motor uses 3 thermostats and has a pressure relief valve at the lower port side of the engine.

Seahorse,

Thanks for the information. I will take the cover off and take a look. Any thoughts on changing the xd50 to the xd100?
