I have a 95 200hp vindicator E200STLE0A. lower unit went out. Put on a lower unit from a Johnson 93 200hp. Smaller gears in lower unit. had a 25 pitch prop. tried out a ballistic 23 prop since thats what was on the lower unit of the motor I took off. can only get 5200rpms, 43mph on a stratos 201proxl. 20 mph slower.
1. Do I have to replace the lower unit with the same heavy duty gears etc?
2. is the gear ratio the same?
3. suggestions on what to do to make it right?
