    Default Sea-Doo 4 Stroke Engines Losing Engine Coolant

    In the past, a few customers have contacted us because their 4-Stroke Sea-Doo is mysteriously consuming engine coolant. We have found that the two hoses inside the hull that are connected to the ride plate/heat exchanger are the hoses that are leaking. The hose clamps that are used will rust and break and when pressure is built up from the cooling system. The antifreeze will then push past the ride plate nipples and hoses. No evidence of coolant can be found in the hull because it is bilged out by the self-bailing system in the ski. Attached are a few pictures of a failing clamps and its location. Replace the clamps with a good marine grade full stainless steel clamp. This should help prevent "mysterious" coolant loss.
