Impeller issues...

[tkawika]

I am looking for a new impeller for my Albin AD-21 Engine... The reason WHY.. enjoy the read... lol.. Any help would be appreciated and than you in advance..

it appears that the ad21 may have two impellers? in any case, can you not measure the size of the aperture and buy one (or two) to fit? conversly, it appears that that was a volvo product/so they may make one? just brainstorming, im an a4 man myself.... good luck

Thanks for the links.. I belong to the Albin group already, but I am checking out the rest. I pulled the impeller last night and its flexible and all the fins are intact. Is there such a thing as being too flexible? I am bringing it to a marine shop to have them find an equivalent.

I am little worried about the "new" rebuilt engine with 84hrs on it. When I purchased it, I had a surveyor come out and he gave me a list of recommendations, but none about the engine. BUT, I should've known better. Bad Me... When I pulled the impeller out the bolts were almost rusted thru.... Oh well, looks like I am going to learn a lot more about an Albin Engine that I wanted too, because the funds are not there for a new engine.

Thank you again..

all fins intact is very good for you, as if they break and go 'down the food chain' they can cause BIG problems. btw, i highly reccomend you pick up a spare or two just to keep onboard. getting to know your engine isnt a bad thing by any means, just a bit of a learning curve. ive got a spare onboard and will check the flexiblity factor out for you but dont know how scientific i can be. IIRC last one i replaced i would rate at 'medium flex' 1=low flex 10=max id rate it at 3 or 4.

AHA! This one looks good--the manual:

AD-21 Handbook

Thanks again for the links. The handbook was a amazing find. It still leaves a couple of things out. Such as oil type and some other stuff which escape me right now. I have removed the heat exchanger and its an aftermarket job, I think because it doesnt look like anything else in any of the Albin literature. I've uploaded a video on youtube.

EDIT: I Cleaned the Heat Exchanger with wood skewers hooked up to my Hitachi 14.4 Drill, haha it seemed to work just fine and then hooked a pump did a 50/50 mixture with some Barnacle cleaning solution. I found the steps here.

Thanks again. Im still having issues locating the impeller, but still searching..
