Continuing with my bass boat restoration- I'm replacing the water pump on my Mercruiser 260/Chevy 350 engine on my Ranger 395V I/o bass boat. The water pump wasn't working like it should. I disassembled it and saw melted plastic- a sure sign that a previous operator ran the engine too long out of the water. I'll show you how I replaced it using a kit I bought online. Thanks for watching and please like and subscribe!

Its easier to put the water impeller on first especially with key lineup, then put on the housing. Thats the correct way its done in service school. Why struggle?
never thought of using a strap!! Thank you!!!! I've been having a hell of a time reinstalling by myself!!! gonna go straight out and try this!!
Awesome! Let me know how it goes
Pro Wrenching that worked!!
@@franklintheman8310 alright!! Glad that helped!
Best video on CZcams of procedure for the Gen 1. Thank you kindly.
Thank you!
I like the way you explained your proceedure
Thank you
Thanks!
Thank you!
Thank you so much. Ready to go back on.
Thank you. Glad my video was helpful!
Thank you so much !!!!
Thank you for this post, love the strap idea when doing this by myself. So I followed your guidelines and got everything apart and back together. I had a hard time getting the lower unit back on, but I eventually did. However, after I got it all buttoned up oil back in I went to start it up with the muffs and My shifter would not move back to neutral. So, I must have done something wrong with gear spline/shift cable when putting it back on. Shifter was in full forward position during the entire time and I do not recall moving the shifting spline at all. Now I'm stuck. Any suggestions, I'm probably going to have to pull the lower unit off again tomorrow and start over??
It sounds like that even though the shifter was in forward gear, the lower unit itself was not in forward gear position. You’ll need to drain the oil (I would save it in a clean container to re-use since its new oil). Then lower the unit enough so that you can shift the lower unit by rotating the shift shaft so that it is in forward gear when you reinstall it. You can test whether or not you’re in gear by rotating the propeller on the outdrive. After you bolt it up, before you put your oil back in, you’ll want to test that it shifts in forward & reverse. When in neutral position, youll be able to spin the propeller freely on the outdrive.
Great video, do you have any information on where the pipe from the lower portion, goes into the upper portion? Mine also go hot and melted that also. I can’t find anything on that on the internet. Thanks
The water pump connects to a pipe in the upper portion of the stern drive which goes through the gimbal through a hose and then passes through the transom to the motor. Hope that helps.
I liked the way you explained your procedure, but I was wondering how you removed the bottom half of the pump base assembly , I have the same problem as you, as to melting problem, but the bottom half seems stuck. Any suggestions on removing this base? Thank you
Take a couple of flat bladed screwdrivers and try to gently pry it up to remove it.
Dont ya just love having all those extra gaskets and seals left over not being used. When I did this for the first time a few weeks backs, I had the deer in headlights look and thinking oh no, I've done something wrong lol. But I ran my boat this weekend at a local lake all day friday and Saturday. My water temp on the gauge never went over 145 degrees. I also changed out my thermostat and installed all brand new cooling hoses. My old thermostat housing had so much rust in it, the ports that feeds cool water to the manifold risers were almost entirely blocked up. I put my thermostat housing in a grit blaster at my work, stripped it completely. Primered and painted it up to look new. Got all of the caked rust out of the inside of it. This old 88 sea ray I bought back in June. I was pretty disappointed at the lack of care and maintenance the previous owner did or didnt do on the boat. I'm attention to detail. Now I've just got to replace all gaskets. Timing chain cover gasket, valve cover gaskets, intake gasket. I have a feeling they are all old and possibly original gaskets. The block has caked oil in some of those areas. But I know me, I'll have to replace the timing chain and gears since tearing into the timing chain cover. 4.3L GM motor.
Yes - I know what you mean, it’s always better if they give you only and exactly what you need in the repair kit so there aren’t any questions after you’re finished. Glad to hear that your boat is running well and staying cool out there on the water after your repair. And it’s nice to have access to those good tools at work to get things cleaned up like removing the rust from your thermostat housing. I know what you mean about buying a neglected boat,but it sure gives a sense of satisfaction when knowing all the hard work doing the repairs allows you to come back to the dock without being on the wrong end of a tow rope.
@@ProWrenching Definitely. It did feel good after 2 full days out in the water and no breakdowns. Everything ran smooth. Only 2 issues I’ve found over the 2 days is the gas gauge don’t go all the to full, stays at 3/4 full after filling up, once the level gets below that the gauge then drops with the level as it should. The second issue is at times at no wake areas, when I stop to back up or forward from neutral position, it dies, and sometimes don’t want to fire. Turns over but won’t fire. I’m thinking that kill switch back by the throttle cables is sticking sometimes. It will fire up after moving the throttle back and forth in and out of gear.
@@ProWrenching on a more positive note, despite it being the original motor, and unknown amount of hours on it, it does have great oil pressure. Well, assuming the oil pressure gauge is reading correctly. When cruising pressure is up over 60 psi.
@@larrywalden626 Sounds like you have good oil pressure & a solid motor and with two full days on the water, sounds like you only have a couple of small bugs to work out. I do have a video on the fuel gauge sending unit and a video on upgrading a shift plate that shows some cable adjustments in there that you may find useful.
With the entire drive unit on the bench should I be able to shift the lever by hand mine won’t move. I replaced the water pump impeller and put the upper and lower back together but the propeller turns freely. I also cannot move the shift lever by hand. It is in the forward position though. I thought the propeller should click when turning it clockwise?? Luv your videos!! ✌️

Hey buddy do you have a video talking about the water tube that the impeller slides/connects to
Not one specifically for that, but you might be interested in my Mercruiser Alpha1 Gen1 stern drive repairs playlist: czcams.com/play/PLqlByoSHFlXuaM5B4aMKEl-UwDamSxH54.html
I looked on the link for the water pump and it is only showing that it contains all required components to replace the water-pump impeller and the upper pump housing, but does not include the lower base. Did you buy the lower base separate, or is there another kit number? Thank you for your assistance and the video's.
Yes- I bought the lower base separately. Thanks for your question- I'll add that to the video description. The one I bought is the Quicksilver 44292A3 water pump base repair kit. I bought it from a "major online only retailer".
What are the Quicksilver part numbers? I think the base may have a different number from the main assembly-
Hi Mel- This is what I bought--- the water pump base repair kit is Quicksilver 44292A3.

Thanks for the info! I had made the mistake of saving a few bucks with cheap aftermarket parts and they lasted a few hrs of run time😂Too much labor involved to do that again and there is also the issue of being stuck on the river or even worse sinking your boat. Have a wonderful Holiday season👍💯👍Your videos have helped me replace most of the parts on my Alpha one -Gen one. My engine starts and runs like new and looking forward to installing my new original equipment Quicksilver Water pump!
@@mellow-2 Thank you- I appreciate the Super Thanks! I’m glad you’re able to make use of these videos and your repairs are going good. I’ve gambled on cheap parts and have lost, so I know how you feel. Happy Holidays to you as well!
Does the kit come with the lower base?
no-The kit linked up in the description does not come with the lower base. The water pump base repair kit is Quicksilver 44292A3.
My friend how are you ?,, brother that link you add in the description to buy the kit bring the lower case I don’t see in the picture!!!
Hello! The base repair kit- I bought from a “major online retailer”. Sorry, I dont have a link for that- just the part number. You can buy it from any shop that sells Mercruiser parts. You can tell them the part number when you order it.
I replace the impeller but I went to lake I see little overheating up and down temperature I may have to replace the case
@@gherickb8181 did the case look ok? You would only need to replace it if it was melted or had physical defects. If it all looks good, you may have other issues. I can’t remember if you had previously said if you have replaced your thermostat yet?
@@ProWrenching previous I replace the impeller was damaged I remember turning the engine for couple minutes whit out water ,, work fine last week new this again and yes I remember the case was melted
Under the plastic water tube is there a o ring, washer or bushing of any kind required? Also is there any rubber parts required on the copper water supply tube that goes upwards from the plastic tube? Thanks for your info!! Mel
Mel - in the water pump housing, there is a rubber seal underneath the plastic tube that seals the copper pipe. There’s also a rubber seal on the upper unit of the drive that seals the copper pipe.
@@ProWrenching Thanks so much for the info -I found a rubber seal with my kit that is about 3/4 inch long and it fits snug into the top of the water pump housing hole. So I guess this is the rubber seal you were talking about. I don't see the rubber seal you mentioned for the upper unit of the drive that seals the copper pipe but the pipe fits in there tight so hopefully I'm good to put it back on. Since I'm replacing a lot of parts on my 86 Mercrusier Alpha one gen one, your videos have really been a blessing. Again thank you so much for taking the time to do the videos and also for helping this aging rookie wrench!!!
That seal I mentioned that came with the kit only bottoms out but only allows the copper tube to sit on top of the seal that goes into the top part of the water pump housing-- too tight to insert copper tube into seal. Hopefully this is ok or else I need to head to a dealer for a part. Thanks again! Mel
Hey Mel- really appreciate the Super Thanks! Thank you! The copper tube should be able to fully insert inside the seal of the water pump housing. If you purchase a new upper half of the water pump housing, it will come with a new seal pre- installed. Thanks for watching!
After installing a new water pump and water pocket part that had overheated I am having issues reconnecting the lower with the upper on my 86 alpha and gen one Mercruiser. I saw on your video that you installed the lower with the outdrive all the way down or so it seemed. Mine is lifted some maybe I should drop it down. I have all the studs lined and slightly thru the upper part and the throttle is in forward. I checked the lower unit to make sure it too was in forward by trying to turn the prop shaft to the left and it would not turn but would turn to the right. I assume this means both throttle and prop shaft are both in forward. Even so it appears that when I turn the prop to the right that the vertical shaft does not turn with it. I'm about two inches or so from mating the two parts. Any advice?!?
Do you think its easier to attach the lower and upper together, then attach to boat? Or attach the upper to the boat, than attach the lower?
In my opinion, it’s easier to attach the lower to the upper and install the entire stern drive assembly all at once. I also have a video on installing the stern drive, if you want to reference that.
Wish I'd watched this before I tried to do this. I am stuck in reverse. Any help would be greatly appreciated.
Sounds like you may have had your lower unit shifted into reverse instead of into drive. You’re just gonna need to lower the lower unit and use your hands to turn the spline shift rod on the lower unit so it is in forward gear and you may have to hold it in place by holding the propeller, and then reinstall making sure that your boat is shifted into forward gear.
What kind of grease are you using?
It was a marine grade grease. I don’t remember the brand- something I picked up either at WM or Tractor Supply.
@@ProWrenching
So just a standard marine grease is what I need! Thanks!
Hi, installed the waterpump rebuild kit. Struggled to reinstall lower drive then it suddenly went. now the drive clicks pretty loudly in forward and reverse in the free directions (when prop turned CCW in forward gear it locks and turns CW, but has popping over a gear or something. 6 pops per prop revolution). Neutral spins freely both directions. Reverse is opposite but same noise as forward.
Sounds like you may need to adjust your shift cable. I do have some other videos that may be helpful. You may want to check this video out on upgrading the shift interrupt switch. czcams.com/video/Sq_VYXlW_oo/video.html. Adjusting the cables is part of that procedure.
Ive done all that and still very little flow to the engine ??
You may also want to check your thermostat.
Thanks!
Thank you sir!
Thanks!
