Greetings, <br /><br />Does anyone have any experience or first hand knowledge of replacing the transom on a '73 18 ft. Glastron (V-186)or similar vintage. The transom and design looks to have some curvature which would make the novice in me somewhat hesitant to dive in. I'd like to update the transom and then paint the boat to go with a Merc Inline 6 from the same era. Is this something that a reasonably handy person can do and make look fairly professional? Thanks for any and all replies.

Re: Glastron transom question

First thing you will want to do is to make sure that the transom is supposed to have curvature to it. A rotted, weak transom with a heavy outboard on it can bow outward, when in fact it is supposed to be straight. Definately research the boat and make sure it should be curved before diving in. Recreating the curve is not a big deal, but we can get into that later, if in fact it should be curved.<br /><br />Yes, it is a project that a handy person can get into. It isn't fun, but it is satisfying. Good luck...

Re: Glastron transom question

i have a 1969 glastron i believe it's v-170 anyways i was told my transom was good by a boat dealer in town so i preceeded to mount a 1973 merc 150 on it, i also put a new floor, seats gauges, steering, the whole nine yards. Then i took it to a marina were i go boating and they said that the transom was completely shot that i would be risking my life to but that boat on the water with the transom that bad. so now i'm gutting the boat and selling everything.

Re: Glastron transom question

I am curious, just how did they assess your bad transom Gumball? Did they actually inspect it, or did some jethro use his "calibrated eye" to tell you it is shot, in the hopes you would pay him to fix it? Too bad you aren't closer, that 150 horse Merc sounds kinda tasty, I wouldn't mind having a bit more juice on the back of the Beast.

Re: Glastron transom question

the guy took the transom saver off and shook the motor up and down a bit and he should be the transom moving with the motor, not good, the motor hits between 120-140 on all cyclinders as of this past april, i put a new water pump in it, new starter selonoid. fuel line.

Re: Glastron transom question

haven't put it up yet, i just left the boat at the cabin for now going to pick it up in a couple of weeks. if you know of anybody who wants to buy the boat and trailer it's a 1969 glastron v-170 with new vinyl, new floor, carpet, new wheels on trailer, trailer is an older e/z loader 5.2 with freshly packed wheelbearings, i have a new rack an pinion steering and all new gauges, all new 3 months ago, but going to part out the lounge seats, have two which were 270.00 a piece. boat just needs a new transom. i want to sign something saying that the buyer know the transom is bad that we if something happens they cannot come back on me.<br />up at castle rock lake in wisconsin 4 people died two weeks ago from a bad transom, it actually was a factory recall for the boat but the people didn't know anything about that recall. kind of freaked me out.

Re: Glastron transom question

Trim the motor all the way up, and place your body weight on the prop end. Even with a solid transom, you will get a small amount of flex. If the flex is large, like the prop end drops several inches, you hear noises, and the transom bows out significantly, it is a problem. Like an airplane wing, you do want a small amount of flex. Excessive rigidity is as bad as too much flex. There needs to be a degree of give in structure, or sudden violent failure can be a result. Anybody can shake any motor up and down and say any transom is bad. By doing the pushdown test, you are placing a consistant load on the transom to test for deflection. I think you will find the transom is in better condition than you think.<br /><br />Also, as a side note, my transom was originally 1 inch thick, full of carpenter ants, floor and stringers were gone, and with a 125 horse motor that boat never failed. I feel you will be alright. <br /><br />That accident, what was the conditions described? How was the boat being driven? If a person is beating the snot out of a boat in rough conditions, a failure is possible, wheras if a person is operating the boat in a safe manner, it won't fail. I would base nothing on an event that happened during a completely different set of circumstances to yours. Good luck....
