I bought a 1979 Glasply 17ft. with a 140 omc. As stupid as I can be, I let my son take out the boat, and he spun the hub in the prop. I took it down to the shop to have the hub pressed, but the prop was old and it fell apart. So, I bought a reconditioned prop, the same pitch and diameter. Now it seems like when I take off it feels like Im towing something. It takes forever to get up on plane. I thought because it was an old boat, it had water under the floor. So I riped up the floor, put in new foam, and glassed it all in. I went through the sterndrive, new bearings,seals and a new waterpump.I took out the fuel tank, cleaned it, new fuel pump,and put in a new water seperator filter.and I still cant get it to come to a plane in a reasonable amount of time. You have to have someone crawl out on the bow to get it out of the water. The prop I got has no cupping to it. I might change the prop to a cupped prop Any suggestions?
