  • Transom Repair

    I bought an older Mako that had the transom raised for a 25 inch shaft motor. Since buying the boat the new ssection of the transom is cracking in the top corner where it meets the boat on 1 side. It started as a very fine crack and quickly opened up to a larger crack approx 4-6 inches long (however not in a straight line) and it opened up about 1/16 of an inch maybe a little less. It appears to have settled down and is not growing any further. Have any of you had any similar experience? Any advice? I am not too concerned with damage from water intrusion since it has not been cracked long and I have kept it sealed however I would like to know if it will stop and how to repair. Help!!!

      I actually had that same problem on my 1972 22'with what was supposed to have a "new transom". Except I hit a wave too fast and came down hard, only to find mine crack on either side of the transom at the corner of the cutout. I ended up having to pull the motor and grind the gelcoat away. It was great, the sellers idea of a transom replacement was replacing only the rotted wood in the transom, which was where the motor sat. So, the seam where the old and new transom plywood met, it cracked. I was lucky and close to shore, but i did take on a lot of water and had to pull the boat asap. I guess this goes to show why you don't cut corners (no pun intended). Do you have any pics of the crack? maybe we can get a better idea why yours happened

                    I am not sure if it is clear in the pictures but the crack really is not in the transom that is to say in the v area. The crack is in the surrounding area of the boat.

                      I can see the pix's fine. It's flexing there. Gott'a stop the flexing.

                      Now what that entail's I don't exactually know, except that it will need more material.

                      But then it could move the flexing to a farther out point.

                        Do you wanna give us a shot of the backing plate for the motor mount bolts? If you only have a plate that spans your top two bolts and not all four, this may be causing a problem. The top of your transom may be twisting out. See pics to see what I mean.



                        I believe a few other guys also have a piece of angle stock (alum) that the motor actually sits on. Anyone got pics?

                          Yup, that was the pattern of my crack I previously described unfortunately. But when i hit the wave i made it a lot worse, all the way down to the waterline. I blamed the transom repair, but if yours did it too, then it might be a mfg deffect. Just because when i ground the crack away, i also found a lot of filler and large air pockets in the filler, marble size. So between that and my poor transom replacement I'm sure it just flexed too much. That must be the spot where the hull and liner are joined since there was so much filler??

                            I will tell you what I was thinking of doing and you can let me know your feelings. I was going to grind the crack and fill it with marine-tex then finish it off with a a coat of glass. By the way I am almost ashamed to say my motor has no backing plate it just has large square washers on all the bolts. After thinking about that I can see how the lack of a backing plate caused to much flex.

                              In my opinion even a backing plate wouldnt help. Your transom apears to need some real help. You can do one in about 2-3 weeks if you get right on it. That way you wont screw up the rest of the season.

                              You might get an estimate from a glass man, or at least his opinion on the best repair. BTW that is a great looking boat, well worth the repairs it needs to be seaworthy. Best of luck. dave
