Put in the original stock impeller and enjoy it for many problem free years to come..

Used over 200 gallons of T6 in supercharged skis... No problems. T6 has higher Zinc and Phosphorous which is what prevents wear and tear.

Who cares... Topic is Rotella T6 synthetic 5W40...

Rotella T6 is better then semi-synthetic BRP(Castrol) Oil.. Rotella T6 has higher zinc/Phosphorous in it, its 5W40, its FULL Synthetic, Its Jaso Ma/Ma2 certified.

Sick pricing.. I can't see more then a $100 of materials.. Build one yourself. All the parts are available on ebay.

Run it with more then a meter of water under you and will not need to replace the plastic wear ring for years.

It can also be a leaking stator cover gasket.

Get rid of it. BRP did stop making them garbage boats for a reason. Dealing with 1 engine is hell, imagine 2x?

Get rid of it and get something that is running or an older 300..

If you do find a boost leak I would still use the 15/21 impeller. The 15/21 will be a bonus on them colder days. Impeller specialists said that the 15/21 will be faster then a 15/20 or 19 or 18 or...

Buy the new ECU from the dealer and have them marry it to the cluster..

I would stick with the 15/21.

Piston Compression any good?

Your still okay.
115 x 10%=126.5

126.5 is greater then the other 125 so your still good.

Remember the word BOOM. Most are just trying to sell you something..

What about reliability? I'm pretty sure BRP has the engine in a sweet spot. What about when weather and water temperatures change on you with the added ignition timing and/or fueling? Fuel octane?...

The flash removes all limiters. It won't make the engine more powerful.

It can be the ECU.

I am referring to pre 2008 units. As presently wired, it has ran for over 30 hours. The 15 amp fuse feeding the fuel pump inside the fuse box is fine, didn't blow.
It may be that the 15 amp feeding...

If your referring to me being a douche?.. Your a scum bag...

It has a relay. The ecu triggers the relay but the fuel pump has to power through the fuse box. ECU needs to sense a load or it won't fire up the engine. Fuse is 15 amps for the fuel pump, bumped up...

I have a set of supertechs but they are installed. They sure look heavier then the WSM titanium retainers. The top shows plenty of titanium bulk like the aquasport.. ...

They look exactly like a WSM copy with titanium stamped on them. I believe Supertechs retainers are also in the 6 gram range..

There is a lot of pushing down on the retainers at 8000+RPMs. I believe that the supertech titanium retainers are also in the 6 gram range. I wouldn't trust anything lighter then 6 grams in titanium...
