    Replacing water pump impeller for first time

    Yep, I know all of that. I can’t reach the flywheel while holding a lower unit and rotating the prop shaft is a lot easier and faster than rigging up something special. I mostly work on 150-250 hp four strokes and my F70. I have gotten to where I have to use a jack to get the 250 back together...

    Replacing water pump impeller for first time

    The splines never line up for me if I leave it in neutral and when it is in neutral there is no way to line up the splines. I leave them in gear so I can align the splines by turning the prop shaft. Tilting it up to use the motor latch is a safety thing that cannot be done on a lot of pontoon...

    150 EFI low oil pressure

    That’s what I was thinking (except ECM bit). I recommended 2 local Mercury shops to the manager. The one on the lake is at least a month wait but the other one 30 miles away is likely have it done in a week or so. He will probably ignore me and take it to the dealer 70 miles away where they...

    150 EFI low oil pressure

    Again, There were no saved faults nor active faults on the techmate. It’s not some random toy I picked up for a one time use. As far as the control goes, if that button is the problem, it can go back to the dealer. I would think it would still be under warranty. Judging from what I have seen...

    Removing water from gas

    Alcohol absorbs water. Doing what you suggest puts more water in the fuel. Putting some water and some fuel in a clear container, marking the line where the two meet, shaking the container and letting it settle will lower the water line indicating alcohol in the fuel if there is alcohol present...

    This doesn’t look right to me

    Mercury 150 EFI. It looks like I have a proper hub kit for it. The nut was loose. Not so the prop rattled but nowhere near the 55.3 lbs feet the book calls for. This boat would have been delivered this way from the store. The same store that I complain about the most.

    It sure seems like there should be a cotter pin or tab washer on that shaft.

    150 EFI low oil pressure

    Here is the picture. Typical ski boat looking control. The center does not push in or it is locked up hard. It doesn’t feel or look like it is meant to. I think it is a 2023 Sea Ray. I don’t have the owners manual. Not my boat. Just one I do light maint on.

    Removing water from gas

    I have poured gas off the top of water and I have sucked the water out from under the gas. Make sure the syphon hose is in the lowest point of the tank if sucking the water out and stop when you start getting all gas. I never had a problem with either. Mower won’t care as long as there isn’t any...

    best way to carry gas to the dock

    We were using eight 30 gallon caddies. We loaded them on a lawn mower trailer when we couldn’t ferry fuel from the marina with a pontoon boat.

    150 EFI low oil pressure

    I checked it with TechMate Pro. Not the best scanner available but it should show all current and stored codes on the motor. There were none. It just concerned me that such serious alarm would not store a code. Intermittent problems are a pain to troubleshoot unless it can be forced to duplicate.

    150 EFI low oil pressure

    Shouldn’t it throw and save a code if it trips an alarm?

    prop nut tightening

    I have removed several prop nuts with my fingers that were installed by people who didn’t see the need for a torque wrench. The prop rattling on the shaft. The last one was installed by a dealership. Some manufacturers have a range where something like 50 pound feet is a minimum and around 90...

    150 EFI low oil pressure

    I will try to remember to take a picture when I go back. I think it looks like a standard side mount ski boat control. I was just notified the low pressure warning came back on so I may be back down there Tuesday to run the boat on the lake to see if I can duplicate it. Or I may just tell them...

    prop nut tightening

    Never needed anything bigger than a 2x4. I keep a piece about 6” long in my truck just for removing and installing props on the dock.
