Just wondering if anyone knows the maximum engine size for the transom as the boat sits very low in the water and has a tendancy to slowly sink down over time untill the transom top is bout 1" below the water line.
250 on a 6.9 is a fairly hefty lump however I would be more concerned about the whole sinking thing.
Do you have a drain bung in the transom if so maybe it is leaking and letting water into the hull hence the sinking.
If not then I guess you need to check the hull for cracks or holes.
