(1) Inspect original engine in boat to verify ordering the correct replacement block. The 806347R50 listed is a non-Gen+ engine and can be identified by the 12 bolts securing the intake manifold. If the intake
manifold on the original engine is secured by 8 bolts, then order 807736R50 Gen+ longblock instead.
(2) Inspect original engine in boat to verify ordering the correct intake manifold gasket. The 27-824326 listed is for use on non-Gen+ engines which can be identified by the 12 bolts securing the intake
manifold. If the intake manifold on the original engine is secured by 8 bolts, then order 27-824326002 Gen+ intake manifold gasket instead.
