how do I check my transum to make sure it is in a safe condition? 75 checkmate v-mate

[tony g]

my 1975 17' checkmate v-mate2 how do I check to make sure my transum is strong enough for 200hp? Is there a good way to reinforce it or do I have to replace it if it is weak? How do I know when it is in an unsafe condition?

You can always drill into it from the inside and see if the wood is wet and being a 75 there is a very good chance that the transom shld be replaced ...There are multiple products and alot of different advice on the subject ...and post up some pics so we can see what you got ...

Stand on your lower unit and jump up and down, if the transom flexes ya got problems.

Sounds like that is going to be a fun ride. Looks great, good luck with whatever you do with it.

week transom

You can always get a 3/8 alluminium plate that has the shape of the full rear of transom and get one made on the inside also but weld two 3/8 vertical triangle to that plate with a flat bar on the bottom of triangles so that you can bolt it to the sub floor, and then on top of those triangle run a flat peice of 3/8 x2 inches wide again and weld horizontaly to the transom plate just above the triangles. Make sure you divide the triangles about 16in. apart so it will not interfear with the bolts of the engine use silicone sealant in between each plates on each side of transom and bolt everything together with nice sst caridge bolts
Good luck

drill into it, preferably with a decent sized hole saw in a couple places so you can really get an idea, mine was solid by jumpin on the motor, hammering it etc, but was woodchips when i cut into it. Easy enough to replace at the end of the day and never have to think about it anymore
