So I got my blackjack 9 and after running a few packs compared to the Impulse 9, I've found my boat is substantially slower and motor seems to get much hotter. The water pick up isn't obstructed and I see no problem with the cooling system other than potentially the water exit line fitting through the hull exit a little tight. After running for several minutes I notice a distinct strong electronic smell when I pop the hatch off and the motor feels like it's getting hot. Being it's a brushed motor could mine just be a dud and replace the whole motor?
