Great video... I got a 95 XR6 and I'm going to change my impeller hopefully this weekend. This will be a first for me. Ive watched this video several times. Looks like it should be a breeze (I hope).

Not a bad video, better if you explained what you are doing

Did you have it in gear? Or neutral?

Thanks a bunch for this!!! Also….thanks for making me feel like I need to completely restore my engine. Yours is so CLEAN

Over torqued the crap out of that impeller housing. The 30 inch lbs is just snug next to nothing. Believe you were using ft lbs. hope the housing didn’t crack.😮

Good video - BUT: Those Nylok lock nuts are meant to be tightened only one time. Never re-use them, as they will fail.

Put down those tools and flag down that ice cream truck.

Hello, I need a little help locating where the hose coming from the “valve thermal air” leads to. It’s the valve located between plugs 3 and 5 on that same engine. Thank you in advance.

I use a hose clamp to compress the impeller to put in the housing. Just leave about 3/16" out on on side with all vanes in the right direction, then slip into the housing and loosen hose clamp and push all the way in. Be sure and coat impeller with silicone grease beforehand!

It's best to have 2 people to do this and better to unplug the spedo hose instead of pulling the hose down (just found that easier for me) also make sure to get the forward and reverse gear in alignment due to it's easy to slide right up beside the top gear...

Great video bud!! I just picked up a 1994 Skeeter with the Black Max 175 and I ordered a new water pump kit off Amazon. I plan on changing mine this weekend and your video will help me a lot! I do have a few questions, is the liquid gasket necessary? If so I need to get some before I start. Did you change out your thermostats? Did you have to wait until your motor got to temperature before it would “pee” at an idle? Also, I was told I couldn’t run mine using water muffs, I have to run in a tank like you did for the water pump to work? So sorry for all of the questions and I do appreciate the help! 👍🏼

I’ve got one not pissing Have on miffs and scared to let idle for more than a minute

Darn you missed the ice cream truck

I have a wire hanging off the left lower side of the lower section of the motor. It's connected to what looks like a capacitor I have a photo but don't know how to upload it here

Sorry maybe its a dumb question but what was that green stuff at the beginning

You left out the part that the lower unit has to be engaged in forward gear

I thought One had to put the engine in forward to get the forward /reverse linkage to line up?

It wasn't much of a detail but a great video...

Did you order that off Amazon?

What gear is the shifter when you pulled lower unit

that engines running too hot, also running without stats by the looks of it.

Have plugged the oil system and began to mix yourself or continue to use oil pump?

man...you are wonferful !! thanks for this too much explain video.

If you take the prop off it's a lot lighter

I noticed what is consistent in all of the Mercury pump videos is what steps are missing when reattaching the lower unit. There is a rubber hose attached to a nipple at the shift housing in all of the videos, but no one mentions what it is or where it is attached. No one includes it in the disassembly steps. In fact, some videos show it missing, but show the nipple connection inside. There was obviously one there before. When I took mine apart, there was no hose, but there was a nipple. I will put one on now, but I have no idea what it connects to outside the lower unit. Someone in the comment section here calls it a spedo hose. Maybe that connects to my speedometer. Also, it is next to impossible to line up the shift rod with its mate above. The mate moves around and you cannot see in there or move it around to match up. That would have been good to know. I bet they all had trouble but left it out of the videos because of all of the cursing. I still haven't gotten mine back together.

Hey! I got the same motor same year 150hp ,is the water pee coming out suppose to be verry hot or its not normal? Thanks

What part number did you use?

Music over the engine running? This is insanity

Wrong tightening impeller cap...

ICE CREAM!!!!

How did you know it was bad?

Awesome video! Is there anything besides all the bolts at the lower unit that might be holding on a stuck lower unit? Ive been battling with mine, apparently the previous owner never removed it to change the water pump. Is there anything up top holding onto the drive or shift shafts? Or do I just keep battling the corrosion

Howdy. Ive replaced the impella and the thermostats on my 1885 150 mariner and was test driving it, there was a steady stream from tell tall, after driving for about 15 mins the alarm went off and there was no water from the tell tale.. i shut the motor down. Please help..

Thanks man helped me out

You didn't see all that water in your lower unit gear lube. Milk shake, you have bad prop and possibly driveshaft seals.

Should the water exiting the motor be hot? Like nearly too hot to touch?

Nice video.

what does the silicone do ? Never seen this done before

Damn Dude... Polish that prop...! Now which way were those impeller blades facing again...??? lol Bolts are meaasured by their thread diameter & thread pitch, NOT THEIR HEX HEAD SIZE...!

Nice little video. The only advise I would give is that when you are adding the lower gear lube, spin the prop by hand a few times to get the air out of the bearings and such.

Did you add red loctite to a stud that uses a nylock?

Do u have to put in gear

Hi

Do u have to put gear in forward befor drop
