Hello All Sea-Doo members,
I am new to Sea-Doo sportboats. I live on the island of Kauai in Hawaii working with youths in videography and water sports. (Check out our website we are trying to construct with our youths here: www.foundationhawaii.itcstore.com)
I would like to hear (email:classic@aloha.net) from Sea-Doo SportBoat members about their maintainance suggestions for operating the boat in salt water. I was told to use Royal Purple 2 cycle oil for the boat and a PWC. Obviously I am a novice in boating.
I bought this particular boat because of the safety and twin engine (speed is needed) and legally registered as a Boat. PWC's are not legal for some of the things we want to do.
We are thinking of time-share, vacation renting our 5 bd room 2bath house that includes the boat and a Pwc with pontoons (safety) and jeep suv. I would like to do this because--riding on the ocean around our island is DA BEST. Kauai was voted as the #2 island in the world by Travel and Leisure visitors to the island.
Being a former surfer (now 60 years old) I am looking forward to filming very large waves for our visitors and public viewing from a viewing angle never before used to show the excitement of surfing and what the jet boat will do.
Any ideas or comments?
Bob
