Rotax engines need more protection as being a powerful engine. I recommend you
disconnect the three oil tank lines, flush & clean, replace the inline oil filter to the
injection pump, replace the two 6"long X 3/32"id oil lines (weedeater fuelline) to
the two RV spigot nipples on RV cover. BRP mineral oil is what I recommend and
use myself, as the benefit is brp ashless oils lubricate the crankseals best, and known
to be less coagulative. Cut open your old oil filter and you will see for yourself. Bills86e

I have two 93 GTX's, thus no RAVE's.
In the summer of 2005 I got tired of paying the high price Sea Doo charges for the oil that they sell, and since my Doo's do not have the RAVE's, I started using Valvoline TCW3 oil and have never experienced a problem.
Now, last month while troubleshooting a PTO seziure problem and it became obvious that I had a defective crankshaft, I was left with no recourse other than disassembling the engine if I wanted to use it again.
I am only a shade tree mechanic, so, it has been a project. The problem I uncovered was the Web on my CS was defective a manufacturing defect, thus not caused by using TCW3 oil.
That said, the company I purchased the CS from told me that there was evidence that my CS bearings had been overheating and related that it was caused by the oil I had been using.
Now, everything I have read about the great oil debate, API TC oil v TCW3 relates that because Sea Doo, unlike all other PWC's use a rotary valve, SD's require a different type of oil that is only found in API TC rated oils.
As pointed out above, my CS problem was not related to the RV, and the RV was in great shape. In fact, it looked brand new.
That said, because of the overheated bearings, I am going to follow the advise set forth in my Operators Guide which calls for use of only API TC rated oils.
That said, the guidance does not translate into using only Sea Doo oil, which I will refuse to use. However, in my case I found Quicksilver PWC oil (Blend of mineral and synthetic) which is an API TC oil.
I chose the blend because my 93's do not have the RAVE's. The cost is $10 less a gallon than the stuff Sea Doo sells and is a blend, unlike only mineral that SD sells.
A few weeks ago I posted a Thread listing all API TC rated oils, so, if you can't find QS in your area, pull up my Thread on the subject.
I wish I had the answer to whether my use of Valvoline TCW3 oil caused my bearings to overheat, however, I don't. That said, I've decided to spend the extra $10 a gallon to be on the safe side.
Gotta go and drop the engine in my hull so I can get my butt to the River and enjoy the summer riding and splashing.
