    Default Se306

    Our SE306 will replace Johnson/Evinrude V6 Outboards from 1979-Current.

    We use the "Ocean Pro" style water intakes. It may look different than some older models, but will function just fine.

    Our unit does not come with the upper driveshaft. You will need to reuse your old upper driveshaft, or purchase a new one from an OE or aftermarket supplier. The upper driveshaft you will need will be the newer style which uses a clip to secure it.

    You will need to reuse your old water pump or purchase a new one.

    You will have to reuse your old shift shaft.

    Our unit comes in a generic color that matches the generic color OMC uses on their replacement cases. You may paint the unit to match your Outboard.

    Default Upper drive shaft installation

    Does the upper drive shaft just press into the lower drive shaft reciever? I can't find anything in my repair manual about how to install it.

    Our units are set up for the newer style driveshafts which use a clip to secure the two shafts together. With this style you just push down on the upper shaft once you align the splines with the lower shaft and you will hear a click as it locks into place. If you have further questions call us at 813-925-7127 8AM-5PM eastern time.
