Ranger-374V

I bought this Ranger off my boss last summer. Here is the back story on this boat. My boss was running down the lake around 50 mph when the lower unit went out. The motor hit rev limiter for a few seconds before he shut it off. They trailered the boat and put a used lower unit in it from a Johnson 150 from around the same year. Since then the boat will bog down to 3000 RPM. You can get it to 4500-5000 if you slowly give it throttle but after a few seconds it will bog down to 3000. You can let off the throttle and do it again and it’ll do the same thing over and over. If you give it full throttle out the gate it will bog down right away. I put a new CDI power pack on it with no change. I checked the compression. It is good. Does anyone have any similar experiences like this that could help me? It’s just odd that it was running great until the lower unit went out.
