It’s mounted to a bracket. So this guy is set in his ways…has an idea and is not going to stray from it. I couldn’t get him to budge 500$ on the asking price. I feel like I’m just lucky he called me and is trying to fix it before I actually tool the boat out and was like hey this thing don’t work!

B-man, I’m in cape cod MA, so it’ll be a little trip to get to MN. That’s awesome though, I appreciate it. I also asked about the SD cards as well. He’s tried it both ways.

Dandorn, I asked the guy about that but honestly he’s a pretty stand up guy and wants to sell it like it is. Either he wants it repaired for 200-500 or he’s going to buy another 1500$ Garmin.

Doesn’t look like I’ll be getting the boat mid week or so next week…which is too bad but hey, win some lose some. Thank you guys for all the ideas!

So it turns on, tries to load, doesn’t really give you the chance to select anything on the menu, starts up and tries to go straight to the location and blacks right out after about 15 seconds. I was hoping there was some kind of magic button hiding in a pin hole.

They call it Monahan’s Mountain on the foothills of Weymouth… legend has it sometimes late at night you can hear a 2 stroke rapping out between swells in the fog.

She said,” yamaha?”
I said,”yes”
She said,”40 horse?”
I said,” right again”
She said,” I’ll be right back I have three oem props in the box”
Came back like 5 minutes later with 2 and she said,”how’s the hole shot?”
I said good.
She said ,”how’s the top end”
I said,” gets up on plane and wants to liftoff”
She said,”here, you want this one, same as yours, just new, shiny, and white, that’ll be 159.99″
I said, “can I have a new cotter pin too?”
She smiles and said,”I’ll throw in a pin for free”

—the legend of prop momma continues

I found a woman who’s husband has ran a prop shop up here for the better part of 50 years. She was dubbed the prop-momma, she took one look at my prop and had it figured in about 30 seconds…

Aye aye aye….im glad the droplets are…”normal”, I have just yesterday taken all plugs and replaced, the only thing I haven’t really done is check the coils, judging from the zip ties on the foot of the boots going on the plugs , I would say they are due for a change, and I’m not too poor to buy three new ones. Mechanics around here are mad busy and will take till the season slows before I could actually find one to check internals and such.. I was hoping I could adjust some carb stuff but was thinking it was a fuel issue. I ran about 4 gallons of high test though it today with decent amount of load and it bogged down a couple of times. Mind you I had also added some k100 to the fuel to hopefully burn out any water in the system…which is exactly what it felt like…it would run run run for about a half hour, then it bogged down once…I idled it back down, waited a second or two, then opened it back up and it blew out whatever was clogging it (I think)…then is did the same thing one the way back to the ramp, about halfway back..(which is ocean boys…ocean) . Same end result, got to the slick water and had WOT for a good 2 minutes, ram like a bat out of hell. I almost feel like this thing is set to pop just barely before it stalls like a car with a 3/4 race cam in it. It has plenty of power…just sputters like stuttering Stanley at idle, especially after it’s been running hard…. Iowaboy didn’t you say once you could get me parts? I’ll be looking for 3 new coils w/wire (because I believe they’re hardwired). I appreciate the swap out coil trick. I will pull it into the garage tonight and check these new plugs I put in and see if they’re fouled at all. I haven’t given up yet, besides, to fit a new 4 stroke 40hp on here is about 9k with the rigging…

The first thing I did when I bought it was run seafood through it…just an old southern habit

After a good bit of gas going through it and finding an oem prop , I think that what I have is top notch. Now if I can just get the idle right I think it will almost be perfect…til it needs a tune up again. I’ve taken care in trying o chase the problem from the cheapest route. First thing was check the gas for water in the separator and polishing filter, little dirty, no water. Next was changing out the old primer bulb and adjacent lines to the outboard…still sputtering at idle. Next I checked the plugs, which were a little fouled out but still “2 strokey”, so I out new plugs in, stuck it in a water barrel and let it run with some k100 in fresh gas… , still sputtering, but not AS bad… , so I took that air handler off the front of the triple carb body and noticed some condensation on the inside of the intakes, wiped it cleaned with a fresh blue shop cloth, sprayed some ether in there to dry it up, fired it up with no air handler box on there to see it breath unrestricted, still sputter a little. so I let it run for about 15 minutes with the fresh gas and shut it off, only to see more build up of condensation on the intakes and butterflies. What gives?? Where is that moisture coming from and is it why my yamo is still sputtering at low idle?

Not 100% sure what the prop is now…pretty old and worn. I was hoping that the specs like model make and year would help me out on just starting fresh.

I did just that. So here’s the update….made it back from the vineyard. Went through a good chop there and back, rip was really moving with the slack tide. Ka-plowed it the whole way back. Realized that I had just enough gas to make it back.. but made it back none the less. I didn’t seem to have any real problems other than the impeller wasn’t really keeping up. I came home and jammed a piece of wire around in there and seemed to clean it out (seaweed maybe?), put the muffs on and it seemed to be peeing like a champ. All in all I think it might have been that 1 MM adjustment I made? Can’t be that right? I had met a friend of mine on an island halfway back and he was saying that maybe I was catching some aeration from unearthed because the motor might be mounted a little high on the transom. If that was the case…wouldn’t that account for the immediate drag and high Rev of the prop? Maybe I’m just sounding like a crazy person…but hey, we’re talking open water boating, can’t be too careful!! I appreciate all the help and ideas…glad I’m part of this clan

so here’s my next update, I put it in the water, got out into the bay, opened it up, started catching air under the prop, dropped the tilt a little more and started running good, in fact, it ran good enough to venture a little further. I had a first mate with me (case she had to paddle…captains don’t paddle lol), I got it into open water (ocean) and got through some swells, ended up in Oak Bluffs which is on Martha’s Vine (from the cape, thats about a 15-20 minute haul through some chop) and it ran strong. Opened it up pretty good once we hit the reef in the slick water. Letting the engine cool now a little before I head back, as I didn’t see a good stream coming from the impeller even when I was going 3/4. I’ll send another update after we get back!

Also….I just checked the linkage, for the most part the forward gear was about on revolution of the plastic connector off dead center, once I checked the prop, did as you said, check the reverse, it was a one revolution off dead center after I had adjusted the forward gear linkage so I left it alone as it still engaged. However, I did realize that when engaged in reverse the prop does not ratchet like forward, it is locked in gear either way spinning. As for this linkage being the problem…I don’t think that’s it, I get that a MM means a lot when gears are meshing together, but I seen no flakes in oil…so it’s either fine?, or I didn’t abuse it enough to make more flakes, and all the flakes were gone because they changed out the gear oil when they winterized it? I would imagine I’d still see some though and I seen none. So I think what you’re telling me is either the props spun or its the sneaky adjustment in the lower end that I can’t get to..

So I drained the gear oil just now, I don’t see any flaking…which I’m kind of surprised about. So I’m assuming that I’m left with a bad shifting linkage setup and it hasn’t ground off the forward gear all the way….or the props spun. Apart from a little air, the fluid looks brand new as well… any suggestions? Model number is 40etld, code :6h4-L, serial no:560163.
Also I included 3 photos, first of the oil, second is a cracked “mount” (the bottom is solid, top has corrosion) and the third is down on the foot, like a weird place for corrosion, and a crack that weeps water… I don’t know if I should be looking for a whole new motor at this point and if this will even make it through this summer, I has most likely been running like this for awhile

Makes a LOT of sense…also, are you really in Iowa??? I can’t bring my unit in that far away!! Also, where the heck would you find a lower unit for this thing if it came to that??

By the time I got back, all places for gear oil were closed…ugh, tomorrow if I can find a place with some oil I’m going to pump it and fill it, I was going to check for metal just for that one reason. How would I be able to check the steering linkage adjustments?? Good looking out!
