I have a 1998 Seadoo Sportster 1800 with Twin Rotax engines. One of the engines is in need of rebuild. My question is can I run the boat with only 1 engine until i get the funds to rebuild the bad motor? I removed the bad engine so that is already out of the engine compartment. Also what if any damage could be done by operating with only one engine? Any advice would be greatly appreciated. Thanks!
