    Well said Chong, you said what I was thinking and was too afraid to say.

    I'll take a guess, and say that's where the power cables will run thru. I did that on my rebuild, mounted the batteries under the port seat and ran the cables back to junction box under the transom. But then again i could be way off the mark.

    With chongs kind words and encouragement! We got all the transom glassed in today! Because we tackled the transom from the outside The transom had to be done in steps- Glass inner transom wall to make stronger, Make new transom timbers and laminate together. Glue and clamp transom timbers in place etc etc. Once all that was completed you are left with around 7mm to glass up or as we did, Used the old transom skin and glued and screwed it to the new transom timbers until it set. This can only be done if the old transom skin is in good condition and has no osmosis in the fiber glass. To lay it up with new glass is just a messy time consuming process for no real extra gain. Once the old skin was glued in and set we polished all the joins out to fiberglass everything back together. We also bored out the engine well drain holes to a 35mm hole and glassed inside them to make them fully sealed. We also fiberglassed over the top of the transom and into the motor well to fully seal the transom and also add extra strength. Tommorow involves sanding the transom back ready for gelcoat.

    It is actually a tube to release air from under the hull when coming up onto the plane. I heard it was a design flaw in these boats that the back of the hull would suck to the water and that was the solution. The underneath of the boat has a pod like design which can cause suction I guess. it goes through the bottom of the hull to the water. So we were thinking of extending it and making it a drain/berley hole from the baitboard.

    Well who would have guessed that.

    Transom all sanded back with small amounts of filler applied to get a completely flat smooth surface. Its just about ready to be sprayed in gelcoat then its fit out time!!! wooo hooo

    Tim, It's almost worthy of a Honda on the back

    I know Garry! You just need to find me one of those low hour cheap models! 150-200 horsies should do it! Putting the old 150 2 stroke mariner back on her for a bit. See how it goes

    So the transom is all finished! Adam finished it off for me doing the gelcoat etc and boy did it come up like a shiny sheet of glass! Does awesome work Highly recommend Adam from Fmi at caboolture. Also decided to put a 12mm thick nylon motor backing plate on and got the motor all bolted back up this afternoon! Plenty of white marine grade sika to seal everything off. Excavator made easy work of it. Actually starting to look like a boat again! Possibly on the water lets say Monday.

    Whats the thinking behing the nylon backing plate - reduce vibrations?

    If applied correctly aides in sealing the transom, reduces vibration and reduces wear on the actual glass.

    My main reason for it was so the motor did not damage the glass or gelcoat on the transom and as Garry mentioned you ensure a really good seal around your bolt holes through the transom.

    I've always wondered how those boats perform with that strange rear end. John Haines moved away from them to the variable dead rise of today. He certainly liked to experiment to find that ideal of easy planing, good ride and stability at rest.

    Just late night pondering Tim. He did a similar thing to that pole with the 21ft HH ski boat.My mate had the mould and couldn't get the boats work well until he put in a tube between the bottom and the transom.

    I've seen them used on Ali boats too so thought it was something to do with vibration.
