jet pump woes

[jarrod white]

replace water pump and new plugs and run the piss out of it.... I would say much more than that and I would be on the hunt for a new motor. I have done the rebuild on the older motors before and it never seems to end very well. My .02

If you decide you want to tear it down, bring it with you next time you are down.. I have a shop and all tools if you don't

Dave,

I've had a lot of bad luck with outboards.  Cooked bottom cylinder, blown powerpacks and on and on.  Literally thousands of dollars later, I can admit now that my folly was in hiring a shadetree mechanic.  We've since parted company.

Like you, I tried to do a lot of work myself- most all of that work was successful, but it was simple stuff that any idiot could do with the right tools. 

I've replaced every electrical component in my Johnson 40, according to Maxrules, SELOC and whatever other resources are out there.  Just disgusted thinking about it so I'm going to quit now. 

The worst part is the general shit-nature of a ruined trip.  Women, buddies, fish- whatever.  And the whole time knowing that you've just been screwed out of money, and that you really tried to give everybody a good trip.

Rant over.

I'm going to buy a new motor with a warranty.  There are a lot of guys who get decades of good service out of an older motor.  Just didn't work out like that for me x 10.  What pisses me off so bad is that this Johnson is 20 years old, but less than 100 hours!  I'm the second owner, knew the first owner as a Grandad, and he was an engineer so followed everything to the letter.  I now use the piston as an ashtray. 

Getting sick again.  Better luck with whatever you decide. 

Damn.

There are few things in life I hate worse than an unreliable outboard. Run it till it blows, then go to the bank if you have to and slap a new one on and your good for a long time. An outboard is what makes Dave, Dave. Splurge on yourself.

Upstream at that

I am afraid to even look at my impeller.  Some pf the literature talks about how easy it is to refile thr front edge of your impeller.  Scares me to even take the thing off even though i have all the replcement or duplicate keys and pieces to put it back. Thrown a lot of gravel out the back of that pump.

It's easy. I've had an issue where mine blew a seal where the grease goes in (be gentle pumping grease into these things when it's cold out). I had to completely disassemble the pump to get to the seal. It's really not a big deal at all. Take photos and notes as you pull it apart.  Every year I remove the grates and file them sharp like a knife, then sharpen the impeller. It helps alot. I'll be glad to help you with it if you want to tackle it sometime.

Why don't you drive down here and help me patch up my boat?  Just kidding......But it's good to know you are a jet boat mechanic.

[MikeA]

I can do that too. You got two spots the size of a quater,, we could fix that up in about 10 min. Then I can take you out and show you how to run the boat.

[David L. Darnell]

what motor did you go with Dub ?

[Dub]

I can do that too. You got two spots the size of a quater,, we could fix that up in about 10 min. Then I can take you out and show you how to run the boat.

And one 4 foot long gash that took the gel coat off. It's about 1" wide by 4' long. Anyway I'll have her up and running by monday if Line-X can fit me in. Im fix'n the fiberglass and then the line-X goes on. Yeah....I think I found the lower limits of draft. There is a lot to learn about a Jet and the river or water levels (lack there of) the boat is really assume it's the captain that needs work.

David, I got a 25hp Jet mercury. It's factory jet.

[David L. Darnell]

I had a 25hp 4 stroker on the metal boat I just sold, did good but as my wife said why have a 25 when they make a 40, curious to see how the 40 does on the Supreme, they do great with 25's.

With the 40, I can get in it when I need to and throttle back and run almost as fast as wide open with less fuel.

[Dub]

I bet the 40 will be great. Ill have to hit you up for a ride sometime.

If your gonna line x it you don't have to fix anything. You might want to spend some time getting to know the boat in a safer location though... I won't say I told you so, but I told you so.

Thanks for offer Mike.  Might call someday.  What is approximate labor time frame to take it off and refile grate and peller??   

Also what curious what you folks use for grease guns. I have been putting the very expensive merc factory grease.  Smaller grease tubes aee about four inches long -+ and less than two inches in diameter.  My current gun is designed makes it very difficult toload the tubes ?  What brand small grease guns are you guys using??

[MikeA]

That job takes a couple hours. If they are bent you can hammer them back flat on a vise. Then sharpen them on a grinder. Pretty easy job.

I just use a standard grease gun and waterproof grease. It's recommended that you  use a tube and force the grease in by hand. This would have prevented blowing the seal on mine.
