Impeller change, bravo drive

[RGPIII]

Are there any tricks to this? I can see it but seeing how i'm not a anorexic midget I don't see how i'm replacing it while still on the motor.

Best bet is to remove the belt and pull the pump completely out to change.......you may have to wait until the circus comes to town to find a willing midget still.

I pulled the backseat and changed it in about 30 mins. My backseat back pops out real quick but not sure about yours. The hardest part is not dropping nuts and bolts into the bilge. A couple beers and you will have it knocked out.

My rear seat doesn't look very fun to remove

Good idea to start the season with a new impeller keep us informed how it goes-I will need to do one in the future and would like to know..

Definately agree with removing the back seat 1st. Much easier to get to the pump & fuel filter...& any parts that will fall into the bilge.

You will be amazed at all the room to work and cleaning you can get done with the seat out. I pull the back and clean a couple times a year. If its never been out it might be a little tough but will save alot of nightmares of getting stuck in the bilge head first. I have gorilla arms so that helps a little haha. It really is not to bad to do and will save some money to go in the tank.

I also pull the backseat to do mine. Gives you an opportunity to check all the hard to reach parts on the front of the motor.

Got it off last night. the way that worked best for me was, to take the fuel filter housing off of the bracket and drop it down out of the way. that allowed for just enough access to the two hoses. then curl up in a little ball and reach your arm under to remove the 3 mounting nuts on the pump then she comes right out. the old impeller wasn't in terrible shape, no missing fins or any damage to it. just quite squished. looking thru the previous owners records it was 3 years old. but only had about 60 hours on it. now to put it back on the next available sunny day.

make sure you keep track of hoses, if you cross them won't pump...ck housing for grooves, many impeller kits come with a new one...the plastic get scared easily..

Make sure you have all the tools ready before you start. Getting in and out of the boat sucks.

I am six/one and had no trouble at all sitting in the bilge to do the repair. I just pulled the back off of the pump.

its quite easy on mine for this the top hose was black and the bottom one is white. plus i took pictures. haha
some very slight surface scratches in the very back of the housing where the end of the impeller meets the housing nothing where the fins contact. really nice and clean heres the old impeller

oh yeah had all my tools ready to go and on the boat. i just found it easier to take the whole pump off.

learned the hard way a few things to make sure of before replacing your impeller. first and foremost if doing it at the beginning of a season. make sure who ever winterized your boat that they actually put antifreeze in the engine not just drained it. creating a huge air pocket.

second when replacing the impeller. use a light coating of dish soap on the inside of the housing, to keep it lubricated until water gets to it. also will help it if not installed the correct direction.

Glad you got it right. You might want to follow the hose from the pump to the oil cooler log and pull it off to check for broken pieces.

 

[RGPIII]

good idea. i found most of the pieces still in the housing. i shut it down right away. again thank you Keith for all the help today.

 

[keith4216]

I had a few little pieces i found. This is what happens when winterizing from a bucket and you get an air pocket.

What is that black thing under the motor. The hose doesn't look big enough to be a bilge

 

[RNGRDVE]

Looks like a transducer for your depth finder.

yup that is for the humminbird depth finder. it was already in the boat when i bought it. it isn't very accurate. I don't use it anymore since the Lowrance HDS7.

I'm 6 feet tall and I can't do it on my 251 unless I pull out the back seat. I tried sitting Indian style and reaching under the engine. It hurt muscles I didn't know I had. My size 13 feet probably don't help either, they kept getting stuck. The seat looks like a pain but it's not bad to do and it gives a ton of access.
