Re: leaky live well hoses
When I bought my 89 Grumman SS the livewell hoses were rubber, they had leaked and I suppose it was why the sold the boat.
I was going to run PVC but figured it could freeze and crack if it ever happened not to drain out completely. I ran clear vinyl tubing, I used an old fishing rod with the guides removed to fish it under the deck and back to the through hull fitting at the stern. I then opened up the floor a bit so I could use a normal fitting on the bottom of the livewell box. I attached the hose with two clamps and some 5200 sealer around all fittings and slid the box back in place and went back to hook up the hose in the bilge area. I also replaced the through hull fitting with one that I can plug to keep the box dry if needed, and also put valves on both hoses.
Mine had a fill hose that ran from the livewell to the stern, and a pump out that ran out the side of the hull with a valve to either empty or aerate the livewell.
All I ever do is open the fill valve underway and it siphons out the water in a big hurry on it's own.
