Lots of things to look at before jumping in!! What can you get for the glassply if you sell it as is. I'm not familiar with your 90 motor but What I see is for 1500 to 2000 a pump is put on your almost new motor and now your looking at 65 horse give or take. Don't know your mechanical abilities but I know a guy can find a used or reconditoned pump and install your self an save some money. Now if you was to go an buy the same set up your looking in the neighborhood of $6000 plus Less the price of the pump can you get enough out of the glass ply to buy a new motor with pump. Does one pull the controls from the glass boat or buy a tiller handle which is going to cost a guess of 3 or 400? It all depends on what your looking for in a sled. With a lighter haul that motor will push a pretty good load up the river. The amount we can spend on a sled rather we sell glass only, fix motor and buy something else whats the end DOLLAR? Looking for used sleds doesn't scare me much But looking for one with a good motor on the back does. You didn't mention a kicker motor but thats another issue. If you do have one how is it going to fit on the back of the sled. Is the shaft long enough for the prop to ride below the boat properly? on the transmon or will you have to put one of those bouncing hanging brackets off the back a shaft extension is not cheap. As far as used sleds I think a guy could look at Stevens Marine in Tigard, Ore. 1-800-225-7023 I believe a search would give you a web site to look at used boats. Ask for Eric he's always treated me real good. You just as well ask about the pump and tiller handle while your talking. No Taxes in oregon I know its a little ways down the road but it might be worth the try. If they don't have a boat with no motor and you see one you like with one on it have take the motor off and put yours on it. Good LUCK
