by your definition it seems that the impeller/pump system is a bit weak. I was getting water, but nowhere near what he was getting. I'm including my video for reference. Looked like about 4-5" max. I also tried blowing air into the water tube and did get air coming out of engine block...

I was hoping that was the issue. I'm not getting enough water through the top spinning the drive shaft as in the video. I'm gonna rebuild waterpump again. Ordered an OEM part so should be able to use the base as well. I just can't figure out why the water pump isn't pumping enough water. the...

Just to make sure I'm clear, the impeller isn't sitting it the middle of the waterpump. As it spins, one side is closer to the side walls. Is this what you are saying? I guess my assumption was that the impeller would have the fins equidistant against the walls of the water pump

I wanted to send an update if someone is in s similar situation. There is a great troubleshooting video on how to check through issues with lower unit. In my case, pump in new waterpump and impeller, spun it on drive shaft, and then installed, but wasn't getting much water up through the engine...

It is. Thanks. short of repeating the steps over again, I'm a bit at a loss. The only thing i can think of is to connect a hose to where the water guide tube connect to the tube that goes to the engine. I don't know the exact schematic of the coolant system with the motor. Maybe somehow through...

I did check compression. I don't remember exactly what it was, but right around 120 on both cylinders. I've never had an outboard overheat, so I don't know how severe it was, but if the plastic washer had melted, wouldn't that prevent the water from running through the system? If tried...

Hello all, End of last summer was out fishing, using kicker and it started smoking and stalled. Didn't see it, but was not peeing correctly. Started messing with it this spring. Motor works fine. Good compression. Figured there was probably salt buildup in water lines. Flushed out all...

I rebuilt the transom myself, and it has held up well to this point. No stress cracks or anything to indicate any compromising of it. I relocated the batteries to the cuddy, got rid of the side saddle aluminum tanks and put my tank behind rear seats. I will look into the Suzuki.

Definitely looking into that. The Merc TOP 155 is 295lbs. The 4 strokes I'm looking at are 350-375LBS. I'm Considering this as I look into different transom materials as well

Hello everyone, I inherited a very old and broken 59 Seafair sedan in the classic way that many of us do, through the promise of a working boat that was far from. After having it for about 6 months, and realizing that it was in bad shape, I decided to rebuild it. Having zero experience with...

Hello, I have an '85 7.5 that i use for my kicker motor. I am needing to replace the throttle cables as mine have rusted out. I have a Seloc manual, but it has almost no info on disassembly/reassembly for the tiller arm (Not a fan of these, but could not find a Merc version for this motor). I...

Hello, I have been a bit confused on this for a while so have been trying to split the difference. On adjusting the float levers it has measurement D at 10mm. I am a bit confused as my carb top has a lip and the diagram does not. If i measure from the top of the lip, the top lever is exactly...

Hello folks, I've been restoring this boat for the last couple of years. I have rebuilt the transom, stringers, and floor, and done a good deal of cosmetic work as well. Having no previous boating building experience, I have had my share of dumb mistakes and oversights, but I have enjoyed the...

Hello, I've been trying to finetune my '88 merc online 6 115. This is the second motor of this type I've had and both have behaved similarly. On this one, it is timed perfectly, all cylinders have good compression. I have rebuilt the carbs. Everything is set up per the manual to fine tune the...

BTW, i recently posted another question about corrosion. They didn't seem to be on the same issue, but it is the same motor, so if threads need to be combined, please let me know! I have been cleaning up my '88 Merc 115hp. It's the inline 6 model. I have a couple of questions regarding setting...

I bought this motor a couple of years ago. I have taken meticulous care of it since; flushing after every trip, and trying my best to control the corrosion that i got when i bought it, but there are some issues that I am running into. A couple of days ago i noticed that the right side ground...

Hello, I have one of those CDI regulators that is designed to replace the older rectifiers on the MERC. It works really well, but currently i only have it mounted by one screw, because of course, the CDI has a different mounting distance then the original rectifier. I need to come up with a...

Hello, I have a '59 Glasspar Seafair Sedan. It came with a solid trailer that i have mostly refurbished. I find that it is difficult to get the boat to load on the trailer well. I have experimented with different depths when i retrieve it, basically same results. The winch pulls the bow eye...

Hello, I was replacing the impeller in my motor a couple of days ago. I noticed some black gooey oil around the water pump as i was disassembling it. The pump seemed to be in good shape, as was the impeller, but i replaced that anyway. I'm just wondering if that is unusual. It actually seemed...

Hello, I have a well functioning '88 115hp motor. I just noticed what looks a little funky on the power trim assembly. It looks like a seal and ring or something. The tilt seems to be working really well, but I'm concerned about the assembly getting contaminated. A new one is pretty pricey...
