Hi everyone, I own a Sea doo gti 130 (avatar pic) on an island in the middle of nowhere in Indonesia. Thanks for reading and helping! Ive already read a bunch of threads on here to solve my problem and it got me almost up to speed. Here goes:
Bought the Sea doo new oct 2019. Its on 50hrs. It lives on a mooring (yes more or less permanently in the ocean). We pick up and drop off on a sandy beach. Mostly cut the engine when we get close to avoid sucking up sand.... but it happens. Have sucked up a rope earlier this year, multiple wraps on shaft, cut it off the shaft. Then recently sucked up a surfboard legrope/leash. Multiple wraps. Cut it off the shaft. Have now noticed increased initial cavitation (but it goes away), and top speed down from 50knots to 35knots (sometimes higher, but we rarely go over 35 anyway). Definite new high pitched whistling which follows rev tone (air entering the bellow?!). Also new is a fine spray of water from the bellows/carbon seal assembly at low rpm and dry white salty patches in engine room. Leak is slight, but its there. The Sea doo is virtually brand new, so I'm not keen to just rip into it. Its out the water now, on its trailer.
Driveshaft:
I tightened the two boot/bellow hose clamps. Tried, but I cant move the carbon seal back from the seal ring, it is tight, but it moves up and down a fair bit. The steel seal ring is tight on the shaft, i can barely move it back on the drive shaft. All looks new and ok.
Impeller/pump:
I managed a peak at the impeller and wear ring, it looks snug and ok. Its unlikely that we sucked up enough sand to damage it already. (But possible. My sons are 13 and 15).
Any ideas (easy fixes??) or am I going to get greasy? Bear in mind I am very remote and a pwc newby. Any parts/tools/manuals will have to be ordered from Jakarta and I will have to do it myself. I could really do with a good link to the right workshop manual. I am a fairly competent bush mechanic and maintain a fully off grid resort. Thanks for reading my long story!
