Hope this is the correct spot for this. I have an Excel 1651 with a Yamaha 40. I am maxing our around 30 mph. When running the more I trim the faster it goes. Problem is it starts proposing and I have to trim back down. I usually run my jackplate all the way up. Height doesn’t change much. Slows a little at lower position. Thinking of putting a hydrofoil on. I get how they work to plane out and all. My question is , a lot of the time I am in really shallow water. I have the motor all the way up and trimmed way up. Nice thing is the Yamaha has low water intake ports and sucks water when trimmed way up. Will the hydrofoil mess this up when going slow trimmed way up?seems like it may pushes the back down.
