2012 130 Super Sport Through-hull Drain Replacement
Posted: Sat Jun 25, 2022 9:26 am
I purchased a 2012 Super Sport in 2021. The anchor locker one-inch Marlon through-hull drain has failed, and the foam in the hull is moist
I plan to use a 316 Stainless Groco TH-1000-WS, https://www.groco.net/products/fittings/stainless-steel-fittings/th-ws-series-stainless/th-1000-ws) as a replacement for the Marlon drain fitting. After I ordered and received the part, I realized the hole in the hull is 1.5-inch diameter. The hole is cut to a larger diameter to accommodate the two-piece mating design of the Marelon part, which leaves more space than I would like for the TH-1000-WS to move around.
I now plan is to use the female potion of the Marelon part as a spacer for the TH-1000-WS and secure the assembly with 3M5200 adhesive
Q1: what should i do about the moist foam in the through hull?
ASIDE: My understanding is that the water-logging problems were remedied years before 2012, [that is, this more modern Unibond hull foam is impervious to holding water]
Q2: what are the negative consequences that might occur by using a stainless steel drain instead of the OEM Marlon part?
Thanks,
Greg
