Deffinantly an upgrade. Welded is the way to go. 15 hp on a noat that size is money. all you need now is a custom $3000 complete rebuild and you will have a brand new boat. deffinantly gonna get the job done for you. If you decide to do any work on it let me know i just redid my entire boat from bare metal up. also redid the trailer. Nice boat!
