AR 190 impeller swap

[aaron jansen]

I've seen people talk about changing their impellers on here for a solas.

I just worked with Dave from impros and he got me setup with a new impeller for my 2015 AR190 but was less than helpful on install.

Are there videos out there on how to do it? Or should I just take it to the shop and pay for it to be done?

here is one write up from the FAQ

I think there are some you tubes on it also, it's the same as a PWC, you should be able to do it yourself, pulling the shaft/impeller should be easy, you may need a breaker bar to remove the impeller, If you ran into problems removing the impeller you could just take it and the shaft to a pwc shop to remove,

@aaron jansen You can do it in your driveway.

Disconnect steering and throttle links at the nozzle (the latter is on top and is spring loaded).
After that it is 4 long 14mm bolts - holding the steering + venturi nozzles to the wear ring. Unbolt, prop up with a flat screwdriver, be gentle. Do not loose little dowels in between the pump segments.
(I just did mine last night in the dark, about 15min swap time; but I do it all the time - testing)

Taking the impeller off, well - that can be easy or not easy at all... Depends on how tight it is stuck on the shaft. As @Scottintexas said, worst case you just take the shaft /impeller assembly to the shop.

Easy unless the boat is older or you have corrosion that can make it hard to wrench the impeller loose. There are special holders that go around the splines on the driveshaft which allow you to hold that end in a vise. Then you need to remember to turn the impeller the correct way since the threads are reversed. You should use the proper high temp grease on the drive spline when you put it back together and also use any sealers when reassembling the jet pump using your service manual for those specifics. Very easy given the age of your boat and it is a great education to see how all of that goes together. Take note of the tools that you use and think about including those in your on-board tool kit in case you ever need to pull the impeller to clear out a rope or something.
