I have a 98 Nitro 640 lx. What is the largest motor I can use? This boat does not have the capacity, weight and maximum HP sticker. Does anyone know where I can find this info. I have called Nitro dealers and Tracker with no luck. I am looking to buy a new motor since this one is no good and would like to get the maximum for this boat.

After doing a little bit of research, I found that the max HP is 90. What engine does it currently have?

I have a 2004 640 LX that I bought this past spring. It came with a 90 hp on it. The boat is fast almost too much for it. It also has a manual jack plate that the motor is mounted center holes and we have to run the motor all the way up on the jack plate to prevent porpoising. It took us a couple of trips out to get it dialed in. But it is fun.
Is it a 4 or 2 stroke? Do you know the weight?

It’s a 2 stroke. The person before me put on an Evinrude Ocean Pro V4 90 hp. I don’t know weight of it, but seems heavy. I didn’t mention before but I also had to put a hydro foil on the motor as well, and that made the biggest help on getting the boat up on plane faster.

That should push that boat around just fine, have fun fishing.

Hey, did you have the new engine already?
And I just want to make sure, is Testy and Testy49 one?
Not sure of your question. Testy and Testy49 are not the same I would say.

I mean for some reason do you own both accounts?
Not that I know of. Unless Testy is an older account that I could have started but I do not have any login info saved for it.
