Yes just did it on an RZ2 last weekend.

Make sure you bilge pump works.

Get a plactic bag and place it over the intake to slow the water down.

how quickly does water enter the boat and how long should i anticipate the swap to take. Mechanically inclined... owner of a car/ marine audio shop. and could this be the fix for my alarm going off when the temp gauge reaches 150 degrees

The fix is easy but harder in your boat. G-money changed mine but I have more room than what you have available in the 24V. Water is almost a non issue if you place a plastic bag (supermarket style) over the intake under the boat. Use some dish soap and a few screw drivers and you can have the entire thing done with in 20 mins. Make sure you know which way the impeller plate goes back on or you can add a bunch of time to the project.

Honestly if your temp is at 150 it is not the impeller. Sounds like you might have problem with your temp relay or thermostat. Tige MD or Lee are the best source of problems like this on the boards.

I carry a plug in the boat that fits the 1"1/4 hose just for that reason. Then you don't have to put anything on the intake. Take hose off pump insert plug tighten hose clamp=no more water.

All good, carry on with change out.

Coach is right, normal operating temp should read somewhere between 150 and 175, but it could still be temp related. The best way to check is to carefully touch the tops of both exhaust manifolds. They should be warm to the touch, but not hot. If one side is hot, then you most likely have a cooling problem that's caused by an impeller that's starting to fail or has failed.

Have you ever changed out the impeller? If not, you're overdue. Some shops recommend yearly replacement, others every other year. They get brittle after a year or so, depending on use. Anything over 2 years and you're really gambling.

Does this depend on how much you use the boat or is it just a good rule to go by? Our dealer said that the amount of hours we put on and the lake we boat in we would not have to replace it very often. Love this site ,learn something new almost every day.

Bibbs, just because you are not using yoru boat as much as we do does not mean that it will not go bad as quickly. The impeller can dry out and become fragile. Once this happens, it's not different than what happens to us. IMO, change every year for the sense of security.

Thanks i will do that.

Are there any detailed instructions to do this? I am going to replace mine as I keep pulling crap up the intake and making it over heat.
