    22í3 Monza transom and stringers questions

    Hello I just bought a monza 22 center console and the transom and stringers are no good. A guy came do give me a quote and he said a 2Ē coosa transom would suffice but the boat has a 3Ē- 3 1/2 atm! Would 2Ē give enough strength for a 4 stroke 250 or 300 or does he have no clue what he is talking about.

    Also should I pay to have coosa installed over just regular marine ply? Itís substantially more expensive for the coosa and I donít plan on keeping this boat forever. If it lasted 30+ years i donít see my self owning this boat for 30 yearsÖ I just want to get it done as fast and cheaply as possible with out spending $650 on each sheet of coosa

    he also said I should do the stringers and floor with pvc foam. But Iíve read a few post on here saying not to use it.

    what should I be paying for a repair like this in Miami?

    thanks in advance

    Help please. Boat has 3” transom atm. Repair guy said 2” would be fine if made from coosa… I don’t think that sounds right

    Don't have any experience with coosa,...so not the best to be given you advice, but you asked. Alot of your strength comes from the way you brace the transom. If you have knee braces, and strong backs, 2" would be fine, without reinforcement 3" probably isn't enough.

    the transom is only tied into the stringers which are 2Ē wide and really tall. Iím considering just using plywood and replacing what it has now. 4 layers of 1/2 which somehow equals to a 3Ē transom. I didnít know a boat had 1/2 inch of fiberglass. Iím not really knowledgeable on boat building or fiberglass. Iíve never bought a boat that needed a floor or transom either. Over 20 boats Iíve owned

    I used plywood in the only rebuild I have done. I suspect it will last my lifetime, if kept out of the weather.Click image for larger version.

    You might run into glass between layers of ply, if your transom is that thick? How about your stringers, they any good?
    I imagine anyone that's done much of this work doesn't come cheap, and the labor is going to surpass material cost, by alot, even with coosa.


    Think about knee braces, strong back, or both if you want to hang alot of weight, or run hard in ruff water.

    I got a quote for $3500 just transom. Itís about 1600 in material with 2 1 1/2 coosa. With plywood itíll be about $700 in material

    the stringers are definitely rotten. And it has no floor. To get the boat back to functioning itís $9500 which I donít think Iím willing to pay. Iím going to do it my self little by little. Iíll definitely be adding extra support for the transom.
