old 18 foot vip br with a small block and merc drive bought it to fix a overheating thing but now i find if you are in the windsheild frame u can shake the sides.more left side than right but the floor is all good im sure the wood is gone under it or somthing this need fixed now or will it make it the summer if i just fix the old 305. its a 77 was cheap just a 2nd boat .all the insides of the boat seats dash everthing oem and looks great .but not knowing about vips is it worth it
