Hi Debbie,

Yes, you can use Sea Foam in your jet boat! Sea Foam Marine PRO is also a great choice – it’s specially formulated to be the best treatment for marine engines like your Yamaha Exciter.

What I’d do: Add a full can of Marine PRO to a low tank of fuel (less than 1/8 tank). Run it for 20 minutes (and don’t be afraid to run it hard) to let the Marine PRO mixture work through the system. That is the best way to clean out your engine and help overcome any problems from fuel gum/varnish (hard starts, rough idle, loss of top end speed).

After you finish the cleaning treatment, add Marine PRO to every tank to keep carburetor circuits clean and lubricated.

Hope that helps!
