Can't go over 2500 rpm's?

[macojoe]

Ok we got the shifter fixed, works like a charm!!

Now its time for the next issue!! Can't get more the 2500 RPM's on the motor when in the water in gear under a load??

We did a compression test, fine in all 6, Great spark in all 6, Motor starts and runs when 3 plugs are unplugged on left, and starts and runs when 3 plugs unplugged on the right.

BS and I are sure it is electric something, but WHAT??

Any Ideas guys??

Thanks!
