Oily film in the bilge finally led back to the depth transducer which had come loose. Need advice on what to use in reseating the oil bath tank. Should I use a sealant that would be permanent, like 5200, epoxy or liquid steel or go with something flimsy like silicone. How long should an adhesive cure before I can refill it with oil? Quicker the better as I'm without a depth gauge which is why I'm leaning toward epoxy. It'll get a super prep cleaning either way. What type of oil do you refill the tank with? It was clear and thin, almost like mineral oil or baby oil. All input appriciated. Thanks.Michael
