Top RPM is 4000 with a 13 X 13 prop - Lost 500-800

Recommended Posts

Seems I lost between 500 and 1000 rpm's. Here is what has been done. Replaced the module and pickup coil in the distributor. Fuel pump also (it died).

It's a 99 Malibu Response 350/325 fuel injected Indmar engine. Could the pickup coil cause the loss? Any other ideas/comments are welcome.

Thank you,

@cth2oskier:  I would check the spark map all through your RPM range.  Was there any specific incident between good top RPM and the 500 RPM loss?   If yes, investigate that.
