Evinrude 25hp (year 74) motor questions

13 posts in this topic

Hi guys,

I just bought a used Lund 14' with Evinrude 25hp, the motor has manual start. First couple days, it was started ok at first pull. But recently last couple days, I just can't get it to start. I'm totally new to boat motors. Any suggestions ? Thanks.

Does the ball on the fuel line pump up, is it getting fuel do you know?

The ball get tight after few squeezes so I'm assume the ball on fuel line does pump fuel up to the engine.

How do I know for sure if it does bump up fuel to the engine ?

You can stick somethink in the end of the fuel line and see if fuel come out. If you are get fuel check to see if your get spark.

take out a plug and pull the rope and watch the spark plug.

Hi Guys,

I tested the fuel line and the result it the fuel does come out from the fuel line.

I also tested its 2 spark plugs and saw that they were sparked, plus the 2 spark plug are pretty much new. Accord to the previous owner, he said he replaced those 2 spark plugs last spring, but I have no problem to replace new one if it's necessary. Note: when I take the 2 spark plug off the engine, I saw the spark plugs were kind of wet(by fuel) at their top where they contact to the engine, not sure if they've gotten too much fuel !? I heard if the engine gets too much fuel at a time, it may not able to run.

I use unleaded 87 and mix with 2 cycle oil for my evinrude.

I heard peoples talked about sea foam, and I've found one from autozone {Please read forum policy before posting again, Thank you}, Is that the right one? how do I suppose to use it ? Thanks.

When your done for the day unplug the fuel line from the outboard for the ride home. Plug back in when you get to the lake.

This will ensure your carbs bowl isn't overflowing and flooding the engine. That is especially true if your trailing with the outboard tilted up.

Squeeze primer bulb up till firm/choke/turn throttle to start position and pull.

I heard that the motor should not be started when it isn't in the water.

if that's true then what is the safest way to start the motor when my boat isn't on the lake ?

Just bought the sea foam can. On the engine, where do I support to spray ? Thanks a lot.

With that motor you'll have to run it in a barrel or garbage can.

The sea foam these guys are talking about looks like this:

And is added directly to the gas.

    • Bummer. Battling a cough/cold here and the snooze alarm won this morning.  Hopefully I'll get out later this week.
    •   I use them and they seem to work fine. I guess with the poppin version I don't really walk them, I just work them in the holes and around other Bassy looking cover. I don't work them real fast. My guess is you would probably want to use the standard style for walking them.   Cret what versions did you test for walking, the standard styles or the poppin versions? 
    • Looked them up.   Personally they seem underpowered but it will depend on how much water you need to remove when you finally need that pump. The water powered pumps performance is based on water pressure. If you have 60+ psi then you can get 500-900 gpm and it looks like you will use 1 gallon of tap water for every 2 you pump out of the pit. For comparison I generally use 3/4 horse pumps at a minimum for the pumps which gives you something north of 3000 gph.   I'm not real sure if code and insurance even allow them so check first. If you have a small house and if the sump doesn't get used much it might be an option.
    • Just returned home last night. Had 3 Jake's come in at 7am on my 1st morning and decided to pass on them. Never saw or heard a Tom the next 5 days. Oh well maybe I learned a lesson. Good luck to all.  
    • Never saw a water driven pump. The ones I use and know if are the battery backup kind. They are sold at all if the big box stores and are around $300 I believe. They run off of an automotive type battery that has a trickle charger attached to it to maintain the charge. You have as much backup power as your battery has capacity and then that pump is dead as well so it's a short term solution.having a generator is very helpful as part of the backup plan.
    • I missed one last night.   Shot a 3D archery shoot yesterday and did really well.  From there straight to my blind for an evening hunt.  Big tom came in to 32 yards. I ranged him, dialed in my sight and slid one just passed him. That's as far as I've ever shot with my bow but was feeling pretty confident after shooting all day. Oh well.   Sitting in another spot right now and as of 6:30 have not yet heard a peep.  Can't sit long today, dang work always getting in the way of my fun.
    • I have been meaning to try to stick a yote too whenever I was out I hoped one would show up instead of a turkey.
    • should have set up in the grass! Uncle went back for evening set up at a pinch point hen and tom came through to go back to roost but no shot!
    • Beside the fun of fooling a turkey and sticking it witj my bow,this is why I love turkey hunting. Slow smoked with apple on the pellet smoker. 
    • Does anyone have a water driven backup sump pump? They look like the cats meow if you live in town. Or does code even allow them? If they are not allowed what is the best battery backup ones?
