I just picked up a used 1989 16ft bass tracker, with A 1979 70hp long shaft merc. At wot rpms at 4700, doing 25mph. Seems real slow to me!The prop # is 48 816704 a40 13p. can you help?
Welcome to iboats.<br /><br />Sounds like you're only running on 2 cylinders. Check the sparkplugs. If one looks significantly different than the others, then we need to find out why. Could be a lot of things, but let's start there. Prop sounds appropriate.
That seems about 1000 rpm's low at wot to me. There is a wealth of knowledge here on the board, It won't be long before someone here narrows it down for ya. <br />Good luck,<br />Dave
Check compression on all cyls. How is the motor trimmed, and are you able to change the trim and gain more RPM's ? What is the hole shot performance like ? How many in the boat at that speed ? Where is the antiventilation plate relative to the hull bottom ? Just a few questions to help narrow down the problem. Good luck.
