I have a 1989 bass tracker 1600tf with a 60hp johnson. When I bought it it did not run. I drained the gas, rebuilt the carbs and replaced the power pack. Now it seems to run pretty good. With my daughter and I it jumps up on plane in about 30 seconds and really hauls around the lake. Last weekend i took my father, wife and daughter out for the day and it struggled to get on plane. Once it planed out it ran about 30-32 around just fine. It would take 5 minutes or more to get up and plane. It would come up to about 12-15 mph at 4000 rpm and just lumber there for a while and finally pick up that last little bit and plane out. Is this normal for this boat? We were right about at the weight limit. I dont really know what I should be expecting because this is my first real boat. I had little fishing boats befor but this is my first one over 10 hp. Also any tips on trimming it so it planes faster? What should I be doing? Thanks. Sam
