I am close to pulling the trigger with Hydro Tech on a flash and possibly raising the rev limiter to 6400 as the research I have done and people I have spoken with feel this is the optimum flash/tune that will provide plenty of performance whether or not you adjust prop/pitch. I'd like to revisit this post and see if anyone has any new information or updates.

Re: Performance chip - ECU flash for Yamaha V MAX SHO VF25O Moritz Chevrolet - 9101 Camp Bowie W Blvd, Fort Worth, TX - Monte Coon (817) 696-2003 any mechanical issues that are for sure from the chip and not just from the user?

any noticeable gains on hole shot and top end speed? If so, what are some of the best brands or places to buy from? Also, for those that have tried this type of deal out, what has been your experience, i.e. We got to talking about performance and we were wondering if they make anything in the form of a chip/programmer for these outboards such as they do for automobiles? My buddy and I each have skeeter bass boats, 21', with Yamaha V MAX SHO® VF250's. I have never had an issue with any of them on my trucks, always gained more performance without having any mechanical troubles.

Normally brands/items such as superchips or SCT Livewire. Such as those that raise rev limiters, provide more torque/hp etc. I have typically purchased an aftermarket chip/programmer for my trucks.
