How can I get my 50 two stroke up to at least a 70? Aren't there people who can change the computer or something? Or can I do something to it? Looking to spend less than 500$. Thanks a ton. :)

Sell your motor and buy a 70. If it were that cheap and easy then everyone would be buying 20 ponies below what is needed..

Bore it out, and put a supercharger with a 9lb pulley. A set of flowmasters and maybe some NOS wouldn't hurt either....

I have heard of people changing out carbs from bigger motors. I've been trying to do that to my 98 6hp mercury. I can't find anything on it though. did you check that?

Typically this is only feasible when your motor is a built on the same platform as a larger HP motor.

Example any of the motors below could be made in to 35 HP fairly cheap because the 20 is the same platform as the 35.

You want to increase your HP by nearly 50% by changing he computer on a 2-stroke.

I just saw an ad that showed Dell was having a sale. If you buythe shiny black one that will get the job done.
