Real newbie here, first boat. Missed out on one I was coming back to compression test and this 1995 FourWinns 5.0 Volvo Penta w SX outdrive and 196 total hrs came up. Everything works. Lake tested, all good, so pulled it out to really go over and seller said his son just called and had another buyer.He had agreed to sell to me today. I bought it without a survey, probably dumb move. Any I came across this (see picture) and Im not sure whats going on, anyone know care to hazard a guess?
