Hi Iâm Wesley Strader, from Springsfield, Tennessee and Iâm on the Yamaha Pro Staff. One little tip on your Yamaha motor, when youâre trimming your motor down if itâs making some popping noises when itâs trimming down, an easy way to solve that is to just trim your motor up, go back and get a little bit of grease, put it on your finger. Thereâs two pistons coming out of the back of your pump on your tram, just rub a little bit of grease on the top of each one of those pistons, and thatâll stop your popping problem.By: Walker Agency
