seadoo gti 130 /2011 / 800H engine revision

[thomasartois]

hellow ,

i have an gti 130 from 2011 with 800h on it .
the jetski looks fine and is always good maintenance but the power of the engine is getting gone
he only rus 75 km/h and from 0 to 30 he runs normal but then he losses some power to get me to te top speed .....

I would like to hold the jetski because its a back up one form friends and kits to come with me .

my question , is it an option to do a full engine revision will it help to get back to te normal performances of an gti ?

i am shure its not the pump or the wearing ring thats te problem ....

sorry for my bad English ...

ALWAYS change the spark plugs first on a 4-tec. Also, is the oil between the lines or above the high mark?

+1 on the sparkplugs. What is your max rpm in and out of water? Any codes showing up on cluster?
