    you need to go thru all the basics before even using the boat. this is all the maintenance that the prior owner didnt do. not to mention your registration, etc. boats loose money daily.

    Inspection cover leak 1984 470

    new doesnt mean accurate. use an IR thermometer. if your motor runs cooler than 140, it will wear out quickly.

    Need help with my 3.7l mcm 180

    ebasic sells GLM parts. the joking response is Good Luck Marine. most are chinese import parts. to properly rebuild the mercruser 470, you are looking at sleeving the block, line boring, head work, etc. get a complete estimate before you start. you may be surprised as to what it will cost you.

    Circulation pump 5.7 L

    any GM SBC marine water pump the pining is your fuel system. you cant put enough hours on a boat to stretch the chain. that would be well over 10,000 hours on the boat
