I have a 2005 Glastron SX with a 4 cylinder 3.0 liter Volvo I/O. I installed a Cabela's Hydro troll trolling plate when it was new and now notice in their new advertising that it is not recommended for Volvos with through hub exhausts and don't even make it in vovo gray anymore. I haven't had any problems so far and was wondering about the reasoning for this exclusion and will it damage my engine at trolling speeds?
