Hello everyone, I am very new to the boating world and I have a few questions about my motor and setup. My friend and I have a 1995 25 Johnson pushing our 17 ft Jon boat, is that too little of a motor to push our boat? Also at full throttle we are only moving at 6 mph up current and 11 down current. Now I dont know anything about boats, but shouldn't we be moving faster? Also riding in other boats it has been my experience that at full throttle usually I have to yell to talk to the other person in the boat, now in our boat at full throttle we can talk like normal, so I feel like we arent reaching full potential on our throttle. My last question would be what can I do to the motor to squeeze better performance out of it?

Re: 1995 25 Johnson

What's the boat rated for for maxium HP ?? Check the compression on it. Your spark should jump a 7/16' open air gap on a spark tester. Then do a cylinder drop test on it to see if you have a cylinder that isn't firing when under power.
