I have typically purchased an aftermarket chip/programmer for my trucks. Such as those that raise rev limiters, provide more torque/hp etc. Normally brands/items such as superchips or SCT Livewire. I have never had an issue with any of them on my trucks, always gained more performance without having any mechanical troubles.

My buddy and I each have skeeter bass boats, 21', with Yamaha V MAX SHO® VF250's. His is a ZX model and mine is an FX.

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?

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.

- any noticeable gains on hole shot and top end speed?

- any mechanical issues that are for sure from the chip and not just from the user?

If your going to do any performance mods on Yamaha motors Hydro-tec is the way to go. They have a ecu flash that will make 300 plus hp.

Thanks for the info guys. Anyone have info as to whether or not these things cause any damage to the engine? I do regular maintenance and everything and just wanted a few more mph with a little better hole shot.

I'd love to do this to my boat but wouldn't be able to use it in tournaments anymore.

Have you checked to see if it will affect your warrantee ?

Outboards typically use a different electronic format than autos (closed loop, rather than an open loop), so no viable chips or piggy back units are available. You ECM can be reprogrammed. Outboards are typically tuned on the safe side since the manufacturer has no idea how the motor will be used, but any reprogramming always carry's a risk.

Hydrotec is the Yamaha guru! I've hung out with him few times and he knows his stuff. I've never felt with Simon but all I hear and see is Hydrotec on 90 percent of Yamaha out there going back to 90s style motors

BBC has the best info. Hydrotec is said to be the best. So far, the only way a yamaha tech can tell if you have a flash is if you raise the limiter. They can see you went over stock rooms without throwing a code. Personally, I won't chance it, plus I think my boat is fast enough. But, there have been some skeeters that gained some decent speed out of it. One issue is the rpm and torque band has a flat spot built in that starts at 5k and is almost flat till 6k. Some guys were having a hard time getting past that spot to reach the extra power you get by raising the limiter. All the info is on BBC.

From what I can tell you really do not gain anything until you start getting higher rpms on a 250. This is a lot easier to achieve on go fast boats.

I did have a older skeeter pass me and leave me last year on Dardanelle. I was running 76-78. Hahahah

When I asked the Yamaha service rep about being able to see it. He just smiled. I'm sure they have a way of telling if anything catastrophic happened. I wouldn't feel that comfortable over 6500rpm for extended time.

Very good to know, thanks. I'll call hydro tec Monday.

As far as warranty, if it's anything like my truck was you just return it to stock before sending it to the dealer.
