I purchased a set of the smart tabs SX for my 1981 Glastron 167 with a 50hp motor. I?m worried about trying to mount them. My transom is not flat once you get beyond the ?V? part of the hull. It is slightly contoured. I figure I have two options. One will be to mount the tabs too far inboard on the flat part of the transom. This will require moving my speedo pickup and finding another way to strap the boat down. My other option is to mount the tabs on the contoured part of the transom and hope they still work OK. It?s not contoured a lot, I can easily form the bracket into position with my hands. The actuator bracket will not be on the exact same plain as the tab bracket though. I?m not sure what to do and because I bought them through a distributer on ebay (130 dollars with shipping and tax) they will not let me return them.
