I have a troll master 2 on my boat. It was a pain to install, because it didn't fit very well. I have the correct kit for my motor, but it still rubbed on my motor cover. I was able to modify it to fit good on my own. Another downfall is that it always has power to the servo, even when switched off(don't know about itroll). I remedied the problem by putting it on its own switch. Those are the negatives. I have no experience with the itroll, but after watching there video the troll master looks a lot less complicated to use. I've had no issues with mine for the three seasons I've had it. Imo unless you plan to add steering control, the itroll isn't worth the extra money.
