Re: Long Shaft Conversion. 15HP Evinrude
Hi Mark and welcome aboard!
You can get the whole kit from a local J/Rude dealership for about $300.
Or being cheap like the rest of us.....d

....search up TwinCity Outboard or ishopmarine....you could maybe get the parts there cheaper. And don't forget eBay. The kits are on there from time to time. Even ask your local dealership if they have a used kit or parts laying around.
Might also think about a service manual also. Will help and pay for itself in the long run. Reprints can be had through Ken Cook Co., they have a site also.
