is this noise normal when shifting

the ratcheting going into gear is normal ,just a shame you ruined the impeller, fried the exaust shutters and most likely damaged the exaust couplings running it without water hooked up.Got a lot of repairs there to do

Thanks for the info but I hardly think running it for the 30 seconds it took to take the video did any damage.
 
That's totally up to you whether you want to ruin your weekend out by not checking out the things that were pointed out to you.
 
10 seconds without water at that rpm is more than enough.
The impeller, water pump housing are melted, replace the pump base at the same time. The 2 seals there contain the drive oil.
While it apart, inspect the water pocket cover for damage/water leakage .
And never run a motor without a water supply

this was only 15 seconds the tube in the upper left is new

well I already launched the boat and drove it around a while with no problems before seeing all these responses. Does that mean all is ok or how do i check the above items? The boat is now in the water at my dock.

Possable scenario`s:
pump base has melt damage, seals damaged, drive oil slowly leaking out, upper drive unit failure will happen
impeller flow reduced ,increase in engine temp above 145 degrees, impeller failure with rapid overheat

so what exactly do I need to order and replace? 2000 Rinker Captiva 192 Mercruiser 5.0, can you tell from the video if that is an Alpha drive?
Is there a video on doing the repairs?
 
http://www.boatfix.com/merc/Servmanl/14/14cover.pdf see if this loads, if yes, burn and save
Plenty of videos of the pump service, do a google search. The GEN II drive uses a slightly different impeller.Has more of a floppy vane vs a rigid vane of the Alpha.When you remove the inpeller there is a cone shaped plastic piece on the drive shaft. the 2 seals are in there, but the replacement ones come with seals installed. Once the drive is split, inspect the water pocket cover in the upper section.

Just my two cents as a boat owner, shade tree mechanic, not a pro.
Impeller is made of hard plastic/rubber that spins with the motor inside a metal sleeve inside a plastic housing. Water is what lubricates and cools it. No water, no lubrication, no cooling. Just friction, it heats up in a hurry!
I change mine every two years . I just (today) replaced my outdrive because the upper gears locked up because of lack of oil. I'm not sure where it went, but it was low.
Good luck
 
You have a gen 2 alpha. The pump housing is Stainless steel. There is no pump base to melt in a Gen 2. You definitely did some damage to the impeller. Your impeller is large and will continue to pump water even after it has damage. The question is, for how long will it work.

Never run the engine with out a water supply and never rev the engine on the garden hose.
 
I was able to download the manual. Thank you Bt Doctur.
So to make sure I understand - There seems to be agreement that I definitely need to replace the impeller. It sounds like the recommendation is to split the drive and inspect all parts for possible damage to determine what I may need to replace in addition to the impeller.
Do you guys recommend ordering parts from this site or have you found better pricing elsewhere?
Thank you

Agree. Decided I have so many projects going right now that I'm going to put this off until the next trip to the lake. That will also give me a chance to read the manual and review videos.. Also will see if I can pick up the impeller and seals locally so if it turns out that is all I need that I don't have to wait on parts after tearing it down. I will most likely have questions once I get into it. Thanks
