2021 sea doo spark leaking

[alexvett21]

So I just took my new sea doo out of storage, decided to put an exhaust on it. I then filled up my hull with water to check for leaks. I noticed I am actually leaking water from the right hull reinforcement board underneath. Its nothing major but it does drip a lot when the hull has water in it. Any idea whats it could be?

Welcome.

On a Spark the engine cooling uses (one of) the long aluminum sections attached to the underside of the hull. The metal board is the cooling plate for the circulating engine coolant.

It sounds like there is a leakage path from the inside of the hull to the outside perhaps where the engine coolant fittings to/from that aluminum plate connect inside the hull.

Welcome.

On a Spark the engine cooling uses two long aluminum sections attached to the underside of the hull. Those boards are the cooling plates for the circulating engine coolant.

Ok, thanks. Tomorrow I will try to find it. Hopefully its an easy fix

It's actually only one of those aluminum plates that is a heat exhanger, can't remember if it's the right or the left one, I think it's the left one, the other one is just a dummy without connections.

Under them you have bolts for the engine mounts, they go through the hull, I think it's at least four on each side. If it's on the side without heat exhanger I guess those bolts are the only way it could leak, unless you have a crack in the hull somewhere. If it's on the side with the actual heat exhanger you also have two large holes through the hull for the bosses for the coolant hoses that potentially could leak.

I guess it leaks enough for it not to only be water trapped behind the aluminum plate? And it's not coolant?

My 2015’s did this same thing. I had the dealer repair them. They did a shitty job. Sold them and bought a svho Yamaha. Best move I ever made imo
