Definitely contact Laz Mesa at Mesa Balancing. He built the motors for my Outerlimits and it seems he put as much care into building my motors as if he were building for his own boat. Mesa is not a high volume sweat shop type engine rebuilder. He is a perfectionist that puts care into each motor and has the experience to put out a motor that is built to last. His website is
www.mesabalancing.com and has his contact info there.
Once you visit Mesa in Miami and meet Laz, you wont need to shop around for options. It will be obvious that you found a good shop. He will bend over backward to build exactly what is best for your needs and can be trusted to do it like he promises.
Feel free to call me directly at 813-227-9779 if you have questions or need advice.
