My port engine smokes a lot when you first start it and then after 10 minutes or so it only produces the amount of smoke you would expect. Boat runs fine when pulling wakeboarders, the problem only seems to be when it is first started.
I would check the compression of the engine. It should ideally be psi per cylinder. If you need help doing a compression test give us a shout, and well give you advice to correctly do one on the seadoo.
