That's fair, I just know a few folks here in the states who own expensive boats that can't afford to maintain them, it's probably a cultural thing.

So I was not actually talking about people that have boats with 500 R’s, was talking about people that have a fishing boat or a center console 115 or 200 hp!

Didn't know that there were Motec ECUs for those engines.

Definitely a cultural thing - Only in America.

Like the "How to survive on a $160,000 income" headline in the New York Times this weekend.

I think they’re all away from 115 HP and up, have ECU that can be programmed

Well, yeah, in that case, better to get a set of bigger engines.

However, if your name is Warren and you want to make the fastest 28 Skater in the world even faster and Mercury does not sell any bigger V8 engines, Motec ECUs are the ticket...

Except the MoTeC is 6x more powerful than a Holley. With the Holley your restricted to modifying the parameters available via their software. With the MoTec it allows you to add your own Tables, Parameters and Channels. It lets the user define how the ECU operates. That's why you see them in these applications.
