Hey guys so I have a 2015 seadoo spark 2 up and it is leaking coolant really bad from a tiny pin hole on the side of the water pump housing. I have just bought the ski and was told it had a small coolant leak but after further investigation I found that it was quite major.
since then I have replaced the water pump gasket, water pump impeller and the front engine gasket but I am still loosing all my coolant from a small hole on the water pump housing
Has anyone got a clue what this hole is and how I stop it from dropping all my coolant
Cheers

If that is the waterpump itself the diaphragm may have ruptured in the waterpump. Your first step would be to see if a local Sea-Doo dealer has a waterpump on the shelf you can hold and look at to see if it is part of the waterpump part.

This is commonly called a 'weep hole' on a cars waterpump and lets you know the diaphragm is bad and it's time to change the waterpump, if that's the way this is also designed.
