If you can read the wrench size on the side of the wrench, you can do the change-out. Remove 4 bolts (per riser), unscrew three worm-gear clamps, remove the hose(s), install the new hose (easily cut-to-fit), reassemble with a new gasket and anti-seize on the new bolts. Done deal.
Not saying this is an issue with your machine, but the entire cooling system is nothing but simple wrenching.
Good luck and happy boating.
Here's a pic of the new riser gasket and a cleaned surface on the exhaust manifold where the riser / gasket attaches. Easy pickings. There's not much inside of there once it's opened up.
