I recently bought a 1969 mako center console with a 115 johnson. The boat is in rough overall condition but is a very sturdy , very fisherman friendly craft. I never test drove the boat and it looked to be sea worthy, also the motor ran good. However, the first time I went out I noticed that upon planing off it nose dive pretty steeply and stayed tilted to the right. This made the ride feel like I was constantly plowing and fighting the steering wheel. At times crashing into oncoming waves so hard that it seemed like I might get thrown out . I adjusted the power tilt/trim but really didn't do much other than over rev the motor. Some one familiar with this boat told me that the rear of the hull (stern) was "warped" downward causing the problem so when I got home I checked it out . Well.. first of all the keel had a pretty sizeable crack which let in alot of water ( maybe 20 gals give or take ) and the stern hangs off the back of the trailer about 2 feet. The left side (port?) has a downward curve (aka hook) as does the other side . I do believe this could definitley be the major part of the problem but not sure . My question is how would I go about fixing this so the boat rides correctly ,is it major structure damage? something That a do it yourselfer could tackle? I will try to get some photos and download them to give more perspective. Thank you !

Re: hooked mako hull

It sounds like you have some rebuilding to do. It is very common for all of the structural wood components of boats from that era to rot away over time. Your boat has a series of structural components that all must work together to support the hull. This includes the hull itself (bottom and sides), a set of stringers that are fiberglassed to the hull (run from the transom to the bow), the transom, and the sole (floor).

My guess is that your stringers are in very bad condition. This probably means that your transom is bad to. If you want to invest the time and money, you will need to strip the boat down to the hull and rebuild it.

All of this is repairable (including the crack in the hull) by you, but it is a big job (mostly time). Many of us enjoy this kind of project. There is nothing difficult about the process. There are a lot of documented projects on this site. Take a look around and you will get an idea of what the project will entail. The good people on this site will support you along the way.

The boat is dangerous in its current condition. I wouldn't operate it again until you know more about the cause.

Also, the trailer sounds like it is way too small for that boat. The end of the boat should be sitting on or very close to the last roller or end of the bunks. There is a lot of weight on the end of a boat and it must be supported.

I hope none of this is a surprises to you.
