2001 XP (# 951CARB) Possible Thrown Rod Bearing:confused:

2002 GTX Bombardier 4-TEC
2001 XP (951) carb

Hi fellow water-sport enthusiasts!
My friend and I went out to Parker, AZ, a few weeks ago to the Colorado river…we live in the “OC” (Orange County, Ca., not Florida) so it’s about a 31/2 hour ride from home.

He takes very good care of these skis, uses nothing but Rotax 2-stoke oil, and maintains it the best he can. His son works on trucks and Dirt bike engines, so they both know a thing or two about a thing or two. Anyway, he was riding the ski, he told me, long and fast, and then heard a noise. He thinks it was a blown Rod Bearing. He also suspects the oil Pump. We will hopefully take it apart tomorrow, and see if there is anything else.

We towed the ski back to the beach and he also noticed an air bubble in the oil Reserve to the oil Pump. As far as he knows, he did not get any water in it, and questions why there wold be a bubble in the oil line because this is a closed system.

We were going to rebuild it ourselves, but checking around for parts would be costly, so we checked out a few local shops (Corona, Temecula, and Mission Motorsports) I believe they all would ship our shortblock out to SBT. We of course, wanted to cut out the middle man and go directly through SBT in Clearwater, Florida, but they told me their engines are on backorder to the 17th. So now we are contemplating going through BRP in Canada and use all genuine SeaDoo Parts.

Anyone have any suggestions, or experienced any problems with either using SBT shortblocks, or would suggest going through BRP in Canada with genuine Seadoo parts.

What could cause this rod bearing to fail? Thanks for any comments or suggestions.
BTW…Is it summer yet?

The oil injection pumps almost never fail on a SeaDoo. The air in the system could be bad. If he let the tank get low... and he was jumping a lot of waves... he could have gotten air into the injectors... and it could have gone lean. (oil lean)

BUT... let's face it... it's a machine. Some times they just fail.

Until you get the drive shaft, and pump off... it's going to be hard to diagnose. It could be a pump bearing.
