Older Evinrude HELP??

6 posts in this topic

My son just purchased an older boat with a 1974 Evinrude Trimuph 70 Hp. We ran it with water muffs on and it ran good. I don't have very good water pressure where I live in the country so we could only run it a few minutes.(Still ice on the ponds up here at least for another week or so)

My question is - where does or is the water supposed to discharge from when running?? Any help would be appreciated before we take it in to a mechanic.

In the pics you will see two holes below the cowling - what are they for?? Thanks much.

well heres what i know... sometimes there is a "tell tale" where water comes out to indicate the engine is being cooled, on my 1959 'rude there is no tell tale. only way i know its cooling is that a small amount of water comes out of the exhaust.

There is no tell tale on that engine. A little might come out the idle relief ports that you asked about, but pretty much all of it will come out through the prop when it is not in the water.

There should be "some" water coming out of those two holes. It should kinda splatter out with some exhuast. They area a small part of the exhaust, I believe the majority will come out thru the center hub of the prop. Bit a little should come out thru those holes.

Thanks much for the help. We hope to find an open landing up here this coming weekend to at least run it some more. I grew up only fishing from shore. My first boat was an old Herters with 1957 25hp.

When you try it in the lake, you will see more due to the back pressure.

    • It would probably be more accurate for you to say you simply choose not to believe it will be a problem.   What happens to your theory if interest rates rise to 5%?  
    • All depends on the district and how many years you have been a teacher.  Although MN is looking for teacher all over.. Our current district decided on keeping befits really high and seeing an increase in pay. Where my mother in-law (down in the cities) they have great benefits but there wages haven't not increased as significantly..    Although my wife is looking to open a daycare up so we knows if she will be teaching after all? 
    • You'll be fine with the door in the V.  I heard at one point that the Lake of the Woods edition was Ice Castle's most popular layout.  I know I see tons of them, but you will have to take some precautions.  I use a Towtector on my truck, which keeps the majority of the slush down.  A piece of tape or a tennis ball over the door knob is also done frequently.  Other than that, you'll have icing and freezing of your door, regardless of where you put it.  Just the nature of the doors we use.       
    • That does happen a lot and it sucks having to play those games.  I took my contract job knowing I was going to keep looking for full time work so it was really just a stop gap to get pay checks coming in and also to gain some experience in a new area and with a different company.  I think i was there less than 2 months total including the 2 week notice I gave after accepting my full time job.  Often times its easier getting a job when you're already working somewhere as you are viewed as more employable.  If you're not working then employers start to wonder why. That where a short term contract job can pay off.
    • I'm lucky enough to have the choice when I start my day, usually head in before traffic gets bad(6:30), but today I woke up and was like..........I'll wait until after rush hour(let that carp melt). We have a guy that starts at 4:30 am, and others that roll in at 10:00 am.   35W-494-Hwy100 on the way in, but I avoid 494 like the plague in the afternoon and cut through Bloomington. Adds a few minutes time that way, but it's always the same amount of time,  I hate hate hate the accordion traffic of 494. Jump on 35W right before the MN river and I have my own lane, no merging needed.   Curious to see how shutting down Hwy 169 is gonna affect things. Might roll in even earlier if need be.   Started working from home on Friday's two weeks ago, it's nice but I don't know if I would ever enjoy working from home full time. Stir crazy and lack of interaction with other folks.   Living on the south side of the metro stinks for taking trips up north. But we live with fewer meth mullets around.   We picked where we wanted to live first and then adjusted how far we were willing to travel for a job.        
    • Ya a saw that, sounds like they have played an easy schedule but you still have to pretty good to have that kind of record.
    • One could also say Koivu has been reborn, that line has been on a tear lately. I think all of them are at or near a point per game for the last 22 games. Not to mention they are doing that while usually getting the job of shutting down the other teams top line. Crazyness!
    • most people are pretty good in the shanty towns that I frequent.  the thing that pisses me off is the guys that come out with there 50 grand fish house and there 5 dollar generator.  instead of leaving it in the back of the truck where it wont bother anyone they drag it 50ft front there house set it next to me and let it buck very annoying.
    • Maybe you can help me understand something.  He mentions his wife is a teacher.  From what I have been told and through reading doc's through the MN Dept of Education, teachers generally get paid the same.  I understand there is a little "bump" for working in the cities, but doesn't the State Teachers Union dictate what teachers make to some extent?  My daughter wants to get into teaching and I was just curious.  I highly doubt a English teacher in Shakopee makes $15,000 more than a teacher in Detroit Lakes when comparing degrees and experience.  Hopefully MJ can offer some insight as well. Thanks!
    • We had kids.   Well it's not really that bad though...
