Hi all,
I recently purchased a 1998 Seadoo XPL, it presents like new and the engine was rebuilt apparently with less than one hour of use on it. I’ve now put over 2 tanks of fuel through it breaking in the engine and started riding hard for the last 30 mins of riding before a rave valve spring slipping off the bellow was reducing the rpm because the valves couldn’t open.
After removing the raves I notice some potentially bad scoring on the pistons. What do you think of this?
I’m worried it could be because I’m riding in 10-12C water (50-54f).
What do you think?
