2000 200 efi excessive smoke

[wa211]

This is a 2000 200 efi on a Sportcraft WA211 on Lake St Calir in Michigan. Had a factory rebuilt power head put on in 2007. Came off the river (not quite full throttle) yesterday into the canal and the engine started to smoke excessively when I slowed down. I didn't notice it smoking on the river. Engine temp was normal and I didn't hear anything unusual. Engine was still running smoothly aside from the smoke. I have a remote oil reservoir. Once we docked I let it sit for about 10 minutes. Started right up but still smoking.

Need to have oil injection system checked, may be a problem with oil pump or a check valve bad.
