196 new transom, tank and electrical

[ulfkdn]

  old 196, one of the 1st ever built; transom finally gave up with fiberglass crack at top edge and the plywood WET.  Did replace the transom with the same marine plywood thickness and fiberglassed, 2-part polyurethane finish coat.  Installed 2 new scupper valves and closed off the center drain hole which was connected to the bilge; installed an auto bilge pump.  When doing the transom work did realize the old tank must leak since there was a strong gas odor.  Removed the old tank and found 5 leaks in it and re-fiberglassed the tank "house".   Had a new slightly smaller (32 gal) aluminum tank made by Luther in Bristol, RI including a new gas level sender.  Install new tank with a carbon canister between tank and vent which is is part of a vented gas fill capped device.   Now doing the new electrical wiring.

Looks like you did a nice job

Looks good...did you insulate around the coffin?, any reason you went with a smaller gas tank?

Hi - I know i'm late to the tread but I've noticed my 170 transom is wet also. how hard is the replacement? seems like you did a very nice job.

It's not hard but expect to do more work than just the transom because you'll have to cut into the floor and liner (sides) and stringers about a foot or more forward to give you room to re-do the transom.

Had similar project on my 84 200XF. Opened up the coffin hatch and original 75 gallon tank was floating in water and corroded on the top.  Junked it and replaced with a smaller 42 gallon tank because my Suzuki four stroke sips fuel unlike the original 2 stroke this boat was designed for.  Framed in the new tank and filled the voids with 2 part expanding urethane foam.  I didn't like the idea of having a 2 foot by 2 foot void below the coffin hatch. Had to move the tank fill with a little help from a welder friend. Also had to move the deck plates to access the new tank connections.

so the transom is replaced from the inside? it seems like it would be easier from the outside. more room to work, less collateral damage.

You can do it both ways - plenty of examples of both here.
