I installed shutoffs in hose #1, prevents water leaving the exhaust water jacket into the exhaust.
Do you keep a tow rope on board? If so can you provide a link for where to order one? I searched over tons with no luck. Not sure if they call it something different.
What size of hose is #1?
Hose #1 is half inch.
I don't have a proper tow rope, but I always have several dock lines and other ropes on the boat just in case.
