18SF Engine well leaky hatch issue

[KOS]

Hello fellow seacraft owners.

I was hoping someone could help me find a solution to a problem I'm having regarding the well area in front of the engine of my 1978 18 seacraft. I currently have a TH Marine Desiginger Series Non Latching Hatch that just fits the width of the well but the quality is not good. The latch tha secures the hatch recently snapped off after light use and the hatch never kept the water out even when the latch did work. The small well area makes it difficult to find many options for quality hatches from other manufacturers. It measures 8.5" x 31.5". The current TH hatch measures 7.5" x 14" at the base.

Any suggestions would be greatly appreciated.

Thank you
