So I was given a 93 bass tracker two years ago this month. First year it ran great like a champ, thus last summer however I was making a run up the white river and at one point we were idling and the current pushed the boat into a rock. Middle of the boat it didn’t damage anything but it hit just hard enough to jolt us. After that we beached to go eat lunch and when we came back and fired it up it started out of the hole shot like always got up on plain range at 5500 rpm’s and was cruising then it just bogged down to 4500 rpm’s. I could kill the motor and it’d start right up. Then if I let it sit for a bit it’d run wot great and then bog again.
We loaded it up and went back to campsite. We then took it to the lake to run it and let me do some diagnostics. Didn’t have another issue the rest of that trip. Got home and took it out on our local lake and it ran great for three days then bam happened again it bogged down. 5500 rpm’s at 35 mph then it’d just drop to 4500 and 24 mph and surge every once in a while.
I got home pulled the plugs and they looked fine. Compression checked out at 115 on all three cylinders +\- 1 or 2 psi (two were dead nuts on). Spark is jumping gap perfectly and coils checked out perfectly within spec.
So the next step was checking my fuel it didn’t have water in it and I notice the vro pump was acting goofy this winter we deleted the vro pump and went premix (the person that gifted me the boat didn’t really maintain it and the alarms are all removed). I went ahead and pulled the tank and completely cleaned it out and put new fuel lines on everything. At this point The only fuel thing I haven’t gotten to are cleaning the carbs (it idles rough and at 1,000 can’t get it to idle at anything less I’m using the reeves method of balancing my carbs). I’m hoping it’s not my Powerpack or anything like that because I’ve never been great at setting ignition timing.
Is there anything else I can do during diagnosis? All of my ohm and voltages seem to be in spec. And I’m using the adapter for my voltage meter. I’ve attached the pic of my model number.
