Is this normal or not?

[Andy4k6]

As per my rebuild thread I have a 1995 speedster (single intake and 2 different solus impellers as per solus recommendations)

I had it out again at the weekend and took a quick video of the accelerations of each engines full throttle, the right goes to the limiter almost instantly but the left takes a bit longer.

The other odd thing I find although it may be normal due to the different impellers is the boat always heads left when the engines are at the same rpm so I doubt it can be the drive not working correctly.

I have new drive line seals and bearings, wear rings, neoprene seals and impellers on both sides so all should be good.

Please see the small video below and let me know what you think.

Many thanks

Andy

that right motor hitting the limiter so much doesnt seem right compared to my 96 speedster but i do not know how much difference the dual intakes make

If you hit both at the same time does the right one still rev limit first? Wich side has the lower pitch

Looking at the impeller finder the left is a 14/19 and the right is a 13/18 so I guess the right is a lower pitch and should rev faster however it doesn't seem to explain why at the same rpm on both engines the boat always needs steering right.

If the left engine was pushing more water I would expect the boat to need steering the opposite way.

So if it is a watter flow difference, if you back off the right throttle a few hundred rpms it will straighten out right? Makes me think if it had the same impellers it would go straight but seadoo did it for a reason. You could switch the pumps and see if you need to steer it left

Are you sure the RPM gauges are correct? Are the jet pumps aligned properly?
