1988 680t Repower question

[southerncomfort1]

Pay attention to the weight difference between your old motor and the ones you are considering. Those older hulls were not designed for some of the heavier motors of today. I know someone that had a older hull boat and repowered with a new 4 stroke at max hp for the rig. With the new motor the boat sits its arse down lower in the water and had to have wave wackers installed

I will second the weight issue, depending if you fish larger rougher water. The boat does handle the water well for its size. I had the same boat was looking at going to a 60 Merc or Suzuk. I had a 55 Suzuk but wanted a newer motor for reliability. At that time the 60 Zuk was heavier. The dealer even warned me the boat would sit lower in the water. At that time the E-tec was not out yet.

This is the most important issue the 2strokers may work better on your older hull?good luck
