HELP! Mariner repair gone wrong?

[lil_jason17]

I've got two seperate issues I really need help with.

I have a 1988 30 HP Mariner ELO(yamaha based). After noticing no water out the "pee hole" I decided to do an impeller change. Wasn't to bad to do, but I have a question. In the first few pics you can see that there is a seal in the upper housing, yet it makes no contact with the shaft. What is this? My dealer cant even find it on their parts drawing. Without it sealing on the shaft, water is free to be pumped up the drive shaft tube.

Secondly, after the impeller change I now have a rubber on metal scraping noise coming from the impeller area, yet I'm almost positive everything went in correctly. Is this normal for a new impeller, like it needs to wear in?

Any opinions or advice would be great. I only got two weeks left to opening day. Also, any opinions on the amount of unburnt oil/gas in the intermediate housing in the last pic?

compare your new water pump parts with what you pulled off. Looks like it's either the wrong water pump kit, or is missing parts. ?

Re: HELP! Mariner repair gone wrong?

Well, I decided that I did enough damage already, lol. I'm taking it into the dealer tomorrow to get looked at. I guess we'll see what happens, hopefully something simple. I hope I can get it back in time for opening day, they said they were pretty busy now with this really nice weather here in Wisconsin.

Any opinions on the oil in the intermediate housing? I know it's an older 2-cycle and I do idle it a lot. But I have no experience with how much is too much, ya know.

Thanks all for your help!

Doesn't seem too bad to me. Especially since you idle it quite a bit. You might think about doing a decarb annually. Seafoam is good stuff. Look under the FAQ section. Hopefully you haven't been discouraged from doing your own maintenance. If you don't have one already, buy a decent service manual... it will probably pay for itself if you can avoid 1 visit to the service dept.

Good luck on opening day!

Re: HELP! Mariner repair gone wrong?

Well thats good to know that the oil doesn look that bad. I usually always do my maintenance especially being a mechanic, but I dont know much about outboards. I do have a seloc manual, but i've read that they are kind of lacking specifics of things. Any opinion on clymer manuals, my merc dealer carries them. I really dont wanna pay huge bucks for the nice dealer manuals.

Re: HELP! Mariner repair gone wrong?

I do know that I have a selcoc for one of my motors that is/was better than the clymer version, but maybe it depends on the motor (?). Watch ebay for a used OEM factory one... I've got 'em that way.

If you're inclined to do more OB wrenching, keep your eyes peeled for a little motor that has good compression, but needs some TLC. Often older ones that haven't been run for years are sold off cheap in garage sale season. You can make a project of bringing one back into service... you'd have to go through the fuel system, ignition, replace water pump and maybe re-seal lower unit... then you can use it as a kicker when you go on big water. Old johnson/evinrudes with magneto (points) ignition are easy to work on. A 6 hp would be great. Don't buy one that is a brand you've never heard of. Too tough to get parts. Makes a good off season project.

good luck

Re: HELP! Mariner repair gone wrong?

I'll have to keep an eye on ebay for that.

I have a 2 HP Evinrude thats probably from the late 70's sittin' in the garage on a stand. We used to use it on our canoe. That thing is a damn nice motor, starts after years of sitting every time.

Re: HELP! Mariner repair gone wrong?

I've got one of them as a canoe motor too .... yup they're pretty simple/bulletproof. If only it didn't make my hand go numb from the vibration, it'd be great!

good luck on the mariner.

Re: HELP! Mariner repair gone wrong?

Well I got the boat back today. The shop took the lower unit off, checked my impeller repair and said it looked good. Then they put a hose on it and said the noise was gone. On my bill it said "Noise is water pump dry. Quiet when water hooked up." OK, except I was running it in a tank of water when it happend. I dont get it. I guess I'll fire it up again Sat. and see if its still there. I also asked them to check for any needed maintenance and they said everything looks really good. At least thats good news, nothing needed and no problems. Unless they just tryed to rush me out cause they are busy. I wish I didnt always think like that, but I'm in the same industry and it happens. 100 bucks for the tear down and inspection. At least it was pretty cheap.
