My tracker 1436 and 9.9 Mercury are doing a fine job getting me into the places i want to go, bu tI have a odd question. The OB has three trim positions: 1is all the way down, 2 is in the middle, and 3 is trimmed up (3 more settings are shallow water and no discussed here) In position one, it makes the boat porpoise when I am by myself, but rides well with about 100lbs on the middle seat. But I get major spray off the transom at throttle. In postiton 2, the bow really rides high while trying to get on plane, rides ok on plane and does not produce any spray off the transom. What is the cause of the spray? Is the transom too low in the water or what?
