Not universal, no response to emails
by Faizal from Calgary, Alberta on June 05, 2012
The transom on my boat is set at an angle, so the actuators are not long enough to reach the transom, although there is not mention of this on the website. The nauticus website says you can convert smart tabs into pro-trollers with the extra attachment, but it does not work with these. These tabs have a stop of 25 degrees, which prevents them from shifing into the trolling position. This was the main reason I bought the tabs. Another $50 down the drain. Nauticus did not respond to several of my emails which made a bad situation worse. Installation will cost me AT LEAST 3-4 times the cost of the smart tabs because of the transom angle. Buyer beware!

My boat is a Stingray 21 LR with the Mercruiser 5.0 Alpha 1. The transom is curved to the outboard because of the built in swim platforms. I want to mount to the outboard but this would put the tabs at an angle to the mic point of the transom and outdrive. is this OK?
According to Nauticus you will actually use the SX9510-80, not the 10512-90. You will have to mount them further in and there is no loss of performance. We can give examples by calling us at the number at the top of the page.
