Help me please! Evinrude motor

Re: Help me please! Evinrude motor

OK, I am confused. Can someone chime in as to why he was able to run this before with no prop nut? It is blowing my mind...

Re: Help me please! Evinrude motor

Why do I absolutely need a new prop? If I put a shear pin through it, and put a prop nut on, won't it work?

And I promise you there was no prop nut on before (and it did run for 5 minutes before I hit that rock) According to the guy I bought it from (I called him an hour ago to see what he had in it) he said he didn't put it in himself but to the best of his recollection it has a cotter pin and castle nut...hopefully someone can solve the mystery with that info.

Re: Help me please! Evinrude motor

Castle nut is the prop nut from what I know. I may be wrong though.

With a prop in bad condition you get unbalances flow which can manifest itself much like a spun prop. Buy a new prop and keep that one in the boat as a spare in case you have to limp back to the launch.

Re: Help me please! Evinrude motor

From my understanding (and this is what I ordered) the prop nut looks like this:

Nothing like this was ever on it when I got it.

Re: Help me please! Evinrude motor

That is indeed a prop nut sir.

Re: Help me please! Evinrude motor

But you said that you thought the prop nut for this WAS a castle nut.
To me, this is a castle nut:

Unless you're saying that there is a castle nut inside of this piece.

Well with the prop in the condition it is in (i know its bent up on the blades) I don't understand why it won't move the boat if I put on the prop nut I ordered (which covers the shear pin I ordered)

I know a new propeller will make it perform better, but if I keep that propeller for now and put the shear pin and propeller nut (cone shaped thing) over it won't it work for me?

Re: Help me please! Evinrude motor

That should be the correct part.
should You'll find out when it shows up.

anyway, I whipped this up for you (and others)

This may help:

probably not much though, as your prop shaft is different, but I think it'll help with the confusion.

Re: Help me please! Evinrude motor

I have just read this post and let me say this

1st: That motor is way to big for that boat.
2nd: You got laid away big time
3Rd: You need to take that thing into someone who knows what there doing before you get your self or someone else killed.
Cut your losses and move on to a more suitable boat. I would also recommend you take a boater safety class as well.
This is not a skateboard or bycycle you can endanger your self and the people around you very quickly.

You jumped at a boat that caught your eye and thought it was a good deal. What you shouldve done is some home work before buying a pos. $1000.00 could of bought you a nice 14ft aluminum boat with a fairly recent motor (80s or early 90s) and trailer in good shape.

Not digging on ya just laying out the facts.

Just a note on compression testing, pull the rope with the throttle wide open.
You will see the compression numbers go up.

Re: Help me please! Evinrude motor

How do you know the boat is a piece of ****? A 1962 motor that was recently rebuilt could be more reliable than a 80's or 90's motor that hasn't been rebuilt. Also the boat is a 14ft. aluminum jb, and it doesn't leak or have any dents. So the boat is certainly not a piece of ****. Also the trailer is a 2009, and in great condition. Once I get the drive pin back in and adjust the idle, and set the "low speed" knob more towards rich I think this thing will run fine.

1st: That motor is way to big for that boat.

I beg to differ. Depends on the boat's actual rating. I used to have a 14' Valco aluminum boat that was rated for a 25 HP. It was so heavy, in fact, that a 10 HP wouldn't get it on plane. That boat may be able to handle the 28 just fine.

3Rd: You need to take that thing into someone who knows what there doing before you get your self or someone else killed.

That's some pretty heavy advice. How many folks here on iBoats didn't know a thing about boats or motors when they first got on this forum? How many of us learned how to wrench on motors and work on our own boats through trial and error? That the OP had enough sense to seek out advice shows he is not assuming that boats are simple toys and treating it as such.

Not laying into you, just presenting the opposing view.

Re: Help me please! Evinrude motor

agreed with above. We all learned somehow.

This is a simple set-up, IMO a decent first boat.

Re: Help me please! Evinrude motor

Ok so here is what remains of the thing that was where the drive pin goes. It definitely looks like it snapped on the threaded end, and the smooth end looks like it was ground down. Its about half the length of the drive pin shaft, and no my drive pin shaft is not threaded, its smooth. Maybe this will help solve the mystery of how the motor was running before the rock?

Re: Help me please! Evinrude motor

Seeing those pics put a big smile on my face. I have to say, that motor is too big for the boat, no question, but who cares.. MAN that would be fun!

Looking at it, it's clear that that isn't some big heavy boat. It's extremely narrow, flat-bottomed, and short. But regardless, it's up to the owner to exercise caution. Just because it's big doesn't mean he can't just drive slower . Heck he'd get better mileage anyway running that at half throttle than a smaller one at full throttle I'd wager.

As far as the deal, well it probably wasn't the best, but hey $1000 isn't a TON to let go. The trailer, while a 2009, is just your basic $150 job from Harbor Freight. I own that exact one (well until I sold my aluminum boat). That boat itself, a couple hundred, and the motor, a couple hundred. So perhaps a bit overpaid, but comon', that thing has character! Love it!!

The parts you ordered will be much better, will make sense to you when you install them. That was rigged to work, surprised the prop didn't come off and sink when it broke.

Re: Help me please! Evinrude motor

Ok the new drive pins arrived today and I put it in the pin hole and it looks like this:

As you can see it sticks out of the hole on each end about a quarter inch. I am hoping that this part that I ordered will cover and hold the pin in, what do you think? (pictured below)

If I understand how this works, then I think that I have found the solution and this thing can run when again when the prop nut arrives.

Re: Help me please! Evinrude motor

I have never seen a prop-shaft like that before

Re: Help me please! Evinrude motor

The prop nut should have indentations that hold that pin in place.
