Optimax or EFI? looking to buy a boat soon Need your input!

Just like the title says. Is one more reliable than the other? Does one run faster and more efficient? Are there any characteristic problems?

thanks for any and all input

Optimax all the way! Faster and much more fuel efficient! Even over Yamaha.

The opti's are very hard to beat....also depends on what horsepower rating? Fuel efficient and performance should be about the same
